All the TH-cam video I watched on fake owls, said they don’t work. Even the mechanical moving owls, had temporarily.reviews. You can still protect those beautiful wooden post. I watched this guy fix a broken porch on TH-cam, he prepared the surface and painted the surface with concrete glue. I Liked your spreadsheet layout with the breakdown of the cost. I wish I had seen this before paid someone else to do my system, I could have saved a lot of money. Still I should be paid for in about 13 years, allowing me about 7 to 12 years of free electricity
Thanks for the great comment! I'll look into some protectant. Glad to hear you'll still come out ahead on your system, I really didn't drive the point home that all that math really also depends on your energy rate. If someone is paying $0.30 a kwh instead of my $0.12 they will recoup much faster.
Alrighty, before I start my journey into this as suburbanite, you hooked me with your build. 1st video that TH-cam suggested that seems very doable after the years, probably because I've been interested in the summer at the start of a dry spell. I'm diving deeper into the channel to see whatever progress/ problems you've encountered. Thanks for uploading this.
Thanks for the comment! I have a few videos about my design and install as well as follow ups. Today is June 15 2024 and it has been total problem free! It was installed in august of 2019. Lifetime power is 52.5 megawatt hours! Or 52,500 kilowatt hours! Our power runs around $0.13/kWh so that's $6800 saved so far.
Nice video Neal. Just for comparison; I know of a contractor installed (26) 365W/panel system with 10K battery all Enphase that cost $40K without tax rebate. So, good on you for putting together a great system at a low price!
Great video, well introduced and presented, Enphase should be paying you. For the gaps between the panels, I would tape the gaps (horizontals first then verticals) and that will eliminate the water/rain falling in between and damage your wood and keep your equipment dry. Tape, like what they use to repair RV roofs (EternaBond). They come in different widths. The gaps actually concentrate the rain falling through and do more damage than an open sky. You may have to add a gutter at the eve, a down spout and drain away from your pad.
Thank you for the comment! If you know anyone at enphase who wants to send me a check let me know!! That's a good idea on the tape, I'll look into that but also not sure how I could reach everything without a manlift or something? Not sure I if i can lay on the panels.
@@NealORussa sheets of plywood would work to distribute your weight over the panel but you need to secure the sheets so they don't slide off and you on them (be careful, use a fall restrain harness). Maybe build a temporary ledge to hold sheets in place. Do the horizontal gaps first then vertical ones second (rain flows downward faster than sideways). I have been researching doing a solar carport and using tape seems (to me) the best way keep the rain out. Leaving the gaps open will render the carport useless for me (a lot of rain during rainy season).
No problem Hugh! I wasn't able to find much followup videos on the Enphase system, so I was happy to make this one. While it may take a while to pay off, it's fun and the rate could go up in the future! Check out my solar design video if you haven't already ran the calcs on your install.
Fantastic video. Thank you for posting. I just installed mine about a week ago. And I'm addicted to looking at production and the sky to see if there are clouds. Lol
Thanks for the great comment! It definitely is addicting at first! Enjoy your system! I'm a few months past year 2 and still no issues. I need to make a 2 year follow up video and report on power generation etc. see if there is any detectable panel degradation.
Thank you for watching! PV Watts is a great tool, but its good to have some real data. I have another video on designing a PV system, so check it out if you haven't already.
Thanks Neal. Great video. Was trying to decide wether to go ahead with the solar as I can only fit 10 panels on the roof. (Live in the UK) where I live we only get 1400 hours of sunshine on average per year. On saying that it would be enough to run some items during the day by setting different start time for the appliances, but the biggest gain for me would be for charging and EV. Although the emphase system costs slightly more, it seems to be a better system. Thank you for your honest appraisal of your system.
You're welcome Mark, thanks for watching! When I was considering the system I could not find any videos of the phone app or website that shows the power generation so I was happy to show that off. 10 panels isn't much, but is better than nothing! Check out my other videos for how I designed the system, which may help with your project.
For exposed pressure treated joists, rafters, etc you can get rolls of rubber membrane that has adhesive backing. Just build, then 'peel & stick' before screwing the roof or decking down. I have used Soprema foundation membrane (3 foot wide rolls) which I cut with a box-cutter to the width I wanted. FAR cheaper than the pre-cut membrane 'tape' rolls.
Doesn’t look like your system is set up for consumption monitoring but I love it on our system. The Current Transformer wiring can travel quite a long way. So maybe it would work for u... thanks again for the great video, cannot get enough Enphase. Next maybe an EV for driving on sunshine!
I decided not to do consumption monitoring, didn't see much benefit for me, meaning I'm going to consume what I'm going to consume... If I want, I can calculate my consumption using the information provided by my utility company. They have a website where i can see the daily kwh delivered to my house and daily kwh I send back to the grid. So using the information from enphase enlighten, I can calculate my consumption with the following equation: Solar Power generated + Power delivered from utility - Power sent back to grid = Consumption. Also, have purchased a Chevy Volt Plugin Hybrid EV, so i wish i had more panels because my solar doesn't cover my 100% of my usage anymore!
Your rafters should be fine they're exposed to very little water and can easily dry after getting wet. Posts will rot faster where the concrete is next to them then they would if you had back filled the hole with gravel. The concrete does not allow air circulation and posts will rot faster then posts surrounded by gravel due to the air space between pieces of gravel. Probably not a huge issue for the posts as the solar panels are shedding most of the water.
Appreciate the comment! I agree there isn't a ton of space between panels for water to get on the rafters, and the posts are somewhat protected by the panels themselves. Thanks for watching!
@@NealORussa That was what caught my eye in your thumbnail (subbed, too!) as I want to protect the evening side of my deck and catch some evening sun with solar panels while doing it. Solar panels are actually cheaper than plywood as there are some re-sellers of commercial panels in my state. Just need some posts... unistrut & about 1/2 the rafters of a 'regular roof'... what's not to like?
@@Le_Comte_de_Monte_Felin yea that's a good way to make a covered deck! Also if you're in the us make sure to take advantage of the new tax breaks. I think it's back to 30% tax credit on the cost of solar install/materials.
No problem! I couldn't find any good videos of the app's abilities before i purchased the system, so I am happy to show potential buyers what it has to offer! Just wish it would have came out clearer...
Yes the problem is I would have to have my consumption meter reader device in my main panel which is about 200' through various existing underground conduits to my iqcombiner box where the envoy is located. So it would be difficult to get it all in the app properly. Now I could purchase and wire in a secondary consumption meter but honestly not too worried about it. Thanks for watching!!
Neal, your video was instrumental in my pole barn build/solar rack with Enphase and 18 panels. thank you, Port P.S. the treated lumber will outlast the system. In thirty years should the pole rot you will easily add extensions to the current concrete.
Excellent video!!!. I see your peak is around 7.6kWh and is probably because you are using 310w Solar Panels. I just finished the installation at my mother's house last week (in Argentina) but I decided to use 370w solar panels because in reality you only get 80 to 90% of specs, plus they may lose some % over the years, besides it was the same price as a 325w panels. During a sunny day in summer (is summer in South America), I'm getting 2.4kWh at peak with 8 Panels and IQ7+ (INT version), little over of the actual peak of each microinverter, and yesterday the PV System produced 19.55kW. this is an small system which is more than enough for what she actually use. PV System is 8 monocrystalline Amerisolar 370w Panels (no the best brand) and 8 IQ7+, 35 degrees inclination (15 is the best for summer) and facing north (0 degree).
Hey thanks for the great comment and make sure to subscribe or check out my other solar videos! You made a good move getting larger panels, would be good to put more power into those inverters! But these did also work out pretty close to the 30' wide dimension I needed behind my shop. Thanks again
at 20:15 you have 86% of the estimation. you could add this number ( 86% =^ 14% losses) to your estimation data basis (at 18:00 ) where you put 0% losses. im not sure if this is the right way, but i guess you can try it as you can change back this number all the time.
Appreciate the thought there. I went ahead and put 14% loss in at 18:00 in the Enlighten website and saved the changes. It didn't immediately update my estimated for 12934 down 14%, but I'll check back with it and see if it changes.
awesome video man. we were paying 400+ here in the winter then I installed an outdoor wood burner for hot water and heat and that dropped the bill down to like 125 in the winter. We are all electric, less hot water from wood burner and winter heat. The pool in the summer cost around $50 a month to run the pump alone. That is the jump we could see when it was in use. I have been looking at solar for about 5 years and have not yet pulled the trigger. I would love to speak to you sometime.
Thanks for the comment! We're all electric here too and I have a pool. It costs a lot to keep that pump running! I also purchased an electric car after I installed my panels, so that has driven up my electric usage. I wish I had more panels! Check out the design video I have to help design your system, then if you'd like you can email me questions at daviesscountytractor@gmail.com.
@@NealORussa HOA is asking for 2. Texas licensed Professional Engineer’s seal stamped on the Solar Array Structural Certification paperwork Know anyone who can provide? I am in Houston, Texas area ?
Heh Neil, great video. You covered a lot, and super interesting. One thing though. You mentioned that when you lost utility power for nearly a week that the system still generated power and the envoy updated after utility power was reconnected. Is this not a problem? Solar installations that are grid tied are supposed to automatically monitor for power outages and shut down any solar production back into the grid until power is restored. If you continue to produce power when the grid is out, then something is wrong and your system poses a threat to the safety of utility workers trying to restore power under anti-islanding regulations and requirements, no?
Hey thanks for watching and the comment! I did not lose utility power for a week, i only lost internet for a week. You are correct with the rest of your comment though, the system shuts automatically off when no grid power is detected, so when the power goes out I do not generate solar power.
Thanks for posting! I'm considering building a similar structure with solar, but adding a roof below the panels and using the space below as an outdoor covered patio. As this structure would be split between recreational and solar use, I doubt the cost of my structure would qualify for the tax credit. Any insight regarding when a new structure supporting a solar system can be included as part of the tax credit?
I would keep track of your receipts and costs for materials used for your structure and mounting solar panels (posts, beams, mounting rails, electrical, etc). I would include those costs as solar structure costs. The roof sheeting and any items that provide the convenience of making it an recreational space, do not include in your tax credit. When filling out tax form 5695 (www.irs.gov/pub/irs-pdf/f5695.pdf), there's only one line for qualified solar electric property costs, theres not an itemized list that they check. Then carry the final number from 5695 form onto 1040 schedule 3 form (www.irs.gov/pub/irs-pdf/f1040s3.pdf). Note that for 2020 the solar tax credit was 26%, in 2021 it goes down to 22%. The credit is currently set to expire at the end of 2021.
Where you had the leak at the top of the 6x6x4 box and relocated the entry to the side. I would recommend a drip loop -- that's where the wire descends below the box entry point and they rises to the entry. Like a 'p' on its side. Therefor water running down the cables will drip off and not enter the side of the box. Overall, nice job though.
Thanks Bill, definitely a good comment! I wish I would have put a drip loop at that box as well as my conduit entry into the IQ combiner box below the 6x6x4.
Not that i'm aware of. Looking back around june this year on a really good day, one panel got about 256watts. Divide by 240volts = 1.067 amps. The IQ7+ max continuous output is 1.21 amps. So that leaves a 0.14amp buffer or almost 12% before clipping. Panels rarely obtain their stated wattage, which is why you should oversize your "rated" panel for your microinverter. The closer to clipping the better in my opinion.
Great video and info. Like, subbed. Question. Does your local building code consider your solar panel setup the way you have it as a roofing and storage area? For example where I live I'm only allowed 35% of accessory building roofing in my backyard. I'm trying to determine if the panels will take away from this total or if it's not categorized as roofing depending on how it's installled.
Hey thanks for the comment & sub! Our codes do not have regulations for roofing area on a property. I suspect that may be due to impermeable surfaces on your lot, generating excess storm water runoff? If this helps at all, i did not require a building permit since it didn't have sidewalls or a true roof. Only electrical inspection. They said if I put roof panels or sidewall panels on it they would have required building permit and inspections. Maybe you could leave a 2" gap between all the panels and that would suffice?
Get a good durable water proof paint/sealant for the top of those rafters. You could pull the gravel away and paint the bottom of your posts too to help those slow the rot. Pull the gravel, wash the wood and give it ample time to dry, then use a water sealant or paint up to a few inches above the gravel. Seems to me that would go a long way. Great video. I am not a homeowner yet so I am not watching for the use/purchase reason but for investing in Enphase rather. You have given me some confidence that they have their stuff together. Can you think of any issues you had with Enphase? How about anything that surprised you positively? Any info or input would be greatly appreciated. Thanks!
Just pour some oil around the base of them after oil changes, it's an old trick in some pole buildings some even put something in place to put oil in the hole to prevent rot.
Travis, I didn't see the 2nd part of your comment at first so sorry for the delay! I haven't had any issues with the Enphase system. As I mentioned in the video, I was really surprised that the envoy kept the energy generation info stored for a week without wifi connection. I also like the ability ease of turning it off and on without any new setup, or the fact that after a power outage, it just starts working again when the power returns. I never have had to go mess with any settings. If i was doing another install, i would skip running the power into my garage sub panel, which feeds my main panel, then out to the meter. Instead i would run heavy gauge cable from the panels straight to the house-side of the meter, and put a tie-in there. That way i would stay out of both of my electrical panels. Also, i could construct a much larger system because i wouldn't have been held back by my main panel amperage rating. When i sized my system, i sized it off my existing house loads. Well, about 6 months after the system was up and running i decided to get an electric car, so now i charge at home off 240v power. So my energy usage has increased substantially. I wish i had more solar panels!
Hey Gary! I don't recall exactly what the cost savings was, but it was a lot! I was looking at ironridge racking, but the unistrut blew them out of the park, in terms of value.
In order to commission the system with Enphase did you have to purchade the upgrade software or did you hire a local installer to set up the system in the enhase app?
No there was no purchase required. I used the enphase installer toolkit app (separate app from the enphase enlighten app). I had to create another username and password but that's it. Check out my other solar video where I do the full install. I talk about it a little bit.
Are you happy with the Mission Solar Panels? They're priced very well and since they are built in San Antonio I imagine they'll hold up in my Florida heat better than Silfab that evidently are known to overheat.
Hey Craig, I haven't had any issues with the Mission Solar Panels! Its been over 2 years now, they still look great, no visible corrosion on frames, no peeling or anything like that and they still work flawlessly.
Hey Crowe! There's two reasons I didn't put in batteries. 1, cost. 2, it requires a more difficult install and well as some more sophisticated transfer switching equipment with the grid at the meter. The location of my meter and electrical panel is in a location that makes it difficult to add this type of equipment (it's behind a cabinet in my mudroom). I believe the new emphase inverter systems are more battery friendly.
Very nice and good looking set up. I have 40 LG 330 watt roof mounted panels, Enphase microinverters and monitoring system. We had it installed 5/2019 and it is covering about 90 % of our generation needs here in SE TX, primarily A/C loads 6 months out of the year. I have acreage to retire on in 5 to 6 years and am considering DIY with a ground mounted system, installation of our current roof mounted system was at least 50 % of the cost. Hope they reinstate the 30% tax credit as well. Several people have approached me and asked questions yet still seem skeptical, I sure don't miss the 350 dollar electric bills in the summer and really like seeing a credit balance built up during the shoulder months. Solar to me is a no brainer, David.
Thanks for watching, I always like to hear about other systems! If you decide to DIY make sure to watch my other videos on designing and installing the system. I'd say its definitely a no-brainer on the decision if you can install and save the labor charges and markup on materials. Unfortunately I had to get my system up and running before Jan 1 2020 to get grandfathered in with our utility company for the net metering at $1 for $1 credit on the kwh i send back to the grid. They haven't announced what they're going to do yet, but there was a law passed in KY that says the utilities can decide what they want to provide as a credit so it might be like they only give 1/2 kwh credit for every 1 kwh you send back. If i modify my system for more panels, they can un-grandfather me as they will set it up as a new net metering account.
@@NealORussa I certainly hope they do not change that 1 for 1 credit, here in TX the utilities currently do same and I have not heard of any plans to change, if that were to happen I may consider using batteries for storage as an alternative option. The technology is advancing and the cost continues to come down, have a good weekend.
Very well done. You're probably underestimating your dollars saved (and thus payback) by not accounting for inflation (price increase) of power over that 20-year span. Also, assuming 0% losses in PVWatts was unrealistic, as soiling and system losses are real. The baseline assumption is 14%, so your production is probably a lot closer to PVWatts' estimate with that baseline assumption.
I'm not sure if I missed something but I didn't see, anywhere in your spread sheets, how much of the power generated is used by you and how much is exported onto the grid, also how much power you buy from the grid during cloudy days or at night.?
Hey thanks for watching! I didn't really mention much on my home's consumption since every home will be different. On average I send power out during the day, and use power from the grid at night. Also, fortunately or unfortunately, I now own an electric car, which I charge daily and it takes 10kwh to charge. My system was designed without that in mind, so I still buy quite a bit of power. You can purchase a consumption meter from Enphase that monitors how much power your house uses vs how much your system generates. I did not purchase that add-on because it would have been difficult to wire up in my application since i tied into a sub panel in the garage instead of the main house panel. I can calculate my household usage monthly though with the following equation: Monthly System generated power from enphase enlighten app, plus energy bought from power company on bill, minus energy sent back to grid (also shown on monthly bill) equals my home's consumption.
@@NealORussa The envoy that you already have in the combiner box will measure import/export (consumption) power as well as generated power. You just need to put a CT in your main breaker box with a small twisted pair wire to the envoy consumption terminals. Then your Enlighten app will show produced, consumed, net imported, exported and imported updated about every 15 minutes. It doesn't matter weather you feed the generated power into a sub circuit or your main breaker box.
your envoy should have a cellular backup connection - u should install it. also get a cyberpower battery backups for all your internet equipment. it cleans up the power and should keep it online for a few hours.
Hey, the envoy does not have cellular capability by itself. There is an add-on module to get cellular through AT&T, but you also have to pay for that connection. store.enphase.com/storefront/en-us/cellmodem-m1-1 No reason really to get it, works fine through wifi and it still uploads the data after an internet outage. My internet was recently down again for about 10 days because the county mowing crew ran over my pedestal. Envoy saved all the data and uploaded it when i was finally reconnected! Thanks for watching!
@@NealORussa yea it is an add-on... but yea you should get a small battery backups for your internet. 100% uptime! lol and yea your solar system is quite cheap compared to the retail pricing... about to pull the trigger on a 11.5Kw 30 LG panels with IQ7+ Microinverters and 2 encharge 10 batteries... total cost is about $50k.......
Do you have full 25 years panels and IQ7s warranty if you installed yourself? I think you need to be install by authorized installer to get full warranty from the factory.
You are incorrect. The warranty applies as long as it is installed in accordance with the manufacturers instructions. enphase.com/sites/default/files/2021-10/March-2017-Enphase-microinverter-warranty.pdf
Hi Neal, Just watched both of your videos and the system looks great. I also enjoyed your payback calculations. One thing you didn't factor in on your calculations though, (unless I missed it somewhere) you aren't accounting for price increases from your utility company. I think a good average is 3% per year. I have seen some reports recently of some utilities that are trying to raise their rates as much as 18% in one year! Nice job on the videos.
Thanks so much for the awesome comment! You're right, i didnt take into account the price increases of the utility company in my calculations. That could be another factor showing quicker recovery of costs! I'm planning to get a 2 year review out, not much has changed but will be interesting to see the annual power generation and see if the system has dipped much over the last year due to panel degradation.
I think the plastic sleeve would only serve to collect moisture as it would have holes in it at some point. The water will run from the top of the structure down the top of the beam and potentially into the sleeve. Just a thought.
Would You please explain how the system converts what DC voltage to what AC voltage through the Enphsse Converters and where is Your battery backup system or do You have one.....I watched both Your videos and never heard You talk about the electrical principles st all....and was disappointed thst someone as smart as You are negated to explain any of the electrical principles....How Does The System Work Electrically....Good Videos....
Hey Neil, thanks for the comment! To be honest, I'm not 100% sure how the panel converts the sun's energy into DC power. I'm also not sure how each microinverter converts the DC power to AC power. But I do know that each microinverter has an constant 240v output and varying amperage from 0-1.21 amps per microinverter based on how much energy is going into them from the panel. When you string them together in parallel the amperage adds together. So i have 3 strings of 9 panels, where each string can output a max of 10.89 amps. They all add together in the IQ combiner box and I send a maximum of 32.67a at 240v to my subpanel in the garage. I do not have battery backup, i am grid tied with net metering through my utility company. You can also view this video, it has some information on my system and also shows my wiring diagram. th-cam.com/video/DzvRXU_zUWE/w-d-xo.html
@@NealORussa I think the input of DC Voltage from the panels into the Micro Converters comes out as AC Voltage going into the panel breakers, as there are 3 breakers for input for AC Voltage and the EnPhase Converter in the panel with breakers monitors and adjusts the AC Voltage going out to Your Main Electrical Meter where it is put into the grid depending on what time of day it is and if the panels are outputting enough voltage to overcome the grid power. In any event... I did learn something about micro converters and the difference between optimizers and micro converters, which differentiates between AC and DC Voltages respectively.... Thank You for Your reply and You have a great looking system....Enjoy!!!🤠🤠
@@bigdognance The inverters do all the work. The only thing in the IQ combiner box is the envoy, which does the monitoring and uploads it to the cloud. The system will work without an envoy, it will work with the microinverters standalone. I prefer microinverters vs a single inverter and optimizers because your home run cable from array to inside your building is ac power which is much safer than running high amperage DC power.
@@NealORussa Oh...OK....That is a lot more accurate than my rendition of what was going on....sheese....so You were "sand baggin" on me...lol....You really do know how it works....Thank You for clarification with the additional information. I'm starting to understand how these micro- converters work instead of a string converter....
Hey there, thanks for the comment! I have never washed the panels. I did some reading about whether or not it was required, and consensus was no, the rain will take care of it. If i were to wash though, i would not turn them off.
Great video Neal! Nice to hear this equipment is running strong for you! I am currently installing almost the same system as a roof top with Enphase IQ7+ inverters and 36 Mission Solar 350w panels. One quick question as a DIY install did you start up your system with the Enphase Installer app or just go straight to Enlighten. They mention "your installer will setup your homeowner account" ? I can't seem to find the DIY startup link? Thanks Neal
Thanks for watching! I used the app on my iphone called Enphase Installer Toolkit. Then you connect to an Envoy using WiFi Peer to Peer (P2P) aka WiFi Direct. There is a button on the Envoy to turn on a P2P network, then it shows up on your iPhone as an available WiFi connection. Once you connect in your WiFi settings, then you can open the app and connect to your envoy. Once you get to that point it was pretty intuitive. Then you can configure everything and set the WiFi Network & password that the envoy should connect to. I did mention in my installation video that you need to be patient during this process because the Envoy needs to shut down, restart, and reset itself during some of these setup steps. I got antsy when changes didn't take effect immediately and I kept trying to check for updated settings and they weren't updated so I would hard reset the envoy and retry, etc etc. Finally I just changed the settings and waited 10 min or so, and everything worked fine.

When i was looking, there were a ton of online resources to provide stamped drawings. What are you using for your array structure? If its wood built like mine, you might try a lumber supply house to see if they have in-house design for new homes, etc. They could design plans and stamp them. If you are using Iron-ridge or any other racking supplier, they can provide you with stamped drawings for their system.

@@xanadunikita7251 if the hoa needs structural information, enphase would not provide that. You need a stamped drawing showing your roof can support the additional load or weight of the solar panels as well as strength of the fasteners holding the panels or racking to the roof. You may want to try a local lumber yard or home builder who can direct you to an architect or engineer to look at your roof and provide stamped calculations showing the roof rafters have sufficient strength.
I don't recall exactly but I think it was around $15k? I have a playlist that contains videos on installation as well as design of this system and it goes over all the details.
Francis, I'm not sure these exact inverters would work on 50hz vs the US standard 60hz. A link to the cut sheet says their nominal frequency is 60hz, but note that the part number is "Q7PLUS-72-2-US". They may sell a similar inverter for other markets outside of the US that use 50hz frequencies. enphase.com/sites/default/files/downloads/support/IQ7-IQ7plus-DS-EN-US.pdf
I did some more digging, here is the international inverter model that runs from 45-55hz. enphase.com/sites/default/files/downloads/support/IQ7-data-sheet-INTL-AU.pdf
Yes, it will work for 240VAC 50Hz, the Microinverter works in a range of 47 - 68 Hz, but you will need the Envoy IQ to change the profile setting when you do the setup (Enphase Installer Toolkit). I will install this in South America where they use 220V 50Hz.
@@FrancisOpokuI will do it at the end of November or December (Argentina). You can download the Enphase Tool kit and register on their website, you can create your array in advance (without microinverters or Envoy) and you can check all the profiles available. I see UK used to have 240v 50Hz, but they are others countries they still use. Selecting 230~240 is not an issue, the microinverter it will always synchronize with the local voltage and it will inject a little more, that way the house will always use the electricity generated from the PV system instead of the grid (higher V and less resistance).
That depends on a lot of factors: your utility rates and net metering agreements, your ability to install yourself, your ability to purchase w/out loan interest, how much sun your region gets, which direction you install your panels, etc. You can check out my other solar video on system design and calculate if its worth it for you. For me, the answer is very much YES!
2 of us are trying to build ground solar. First one is going against the Town's building board, he's on 3 acres and wants to put up 42 panels. I'm on 6 acres and I want to put up what Neal did, 27 panels. My town limits solar ground based to 120 sq ft.
Wow rough crowd over there. What part of the country is that? I'm not sure why it would be discouraged, especially on a lot of that size. It would be different if you were right in town or something!
@@NealORussa I’m in Wisconsin. The town I live in is not very friendly to solar. They want a design and specs and the hoops they are making me jump through are horrible. I’m trying to DIY to save money and this isn’t helping.
@@bmoulas tandem solar systems will make you a line diagram and pe stamp it. If you need stamped drawings for the wood structure go to a home builders lumber supply house and they usually have an engineer or architect that can draw up plans and stamp them. I would come to them with a sketch already drawn up of what you're thinking to build and they could size the lumber and fasteners.
@@NealORussa They want $400 for a design, seems steep for a ground based install. I wrote them over the weekend, hopefully they reply and maybe I can find out why it's so expensive.
@@bmoulas was that the architect or the electrical engineer at tandem solar? Your other option for structure would be a ground mount system like iron ridge. They will supply you with pe drawings.
Hey Tom, i guess i meant i don't like the bird droppings on the wood structure or on anything i have stored underneath the panels. So in that sense, I guess i mean the bird poop is annoying, not so much the birds themselves...
All the TH-cam video I watched on fake owls, said they don’t work. Even the mechanical moving owls, had temporarily.reviews.
You can still protect those beautiful wooden post. I watched this guy fix a broken porch on TH-cam, he prepared the surface and painted the surface with concrete glue. I Liked your spreadsheet layout with the breakdown of the cost. I wish I had seen this before paid someone else to do my system, I could have saved a lot of money. Still I should be paid for in about 13 years, allowing me about 7 to 12 years of free electricity
Thanks for the great comment! I'll look into some protectant. Glad to hear you'll still come out ahead on your system, I really didn't drive the point home that all that math really also depends on your energy rate. If someone is paying $0.30 a kwh instead of my $0.12 they will recoup much faster.
Alrighty, before I start my journey into this as suburbanite, you hooked me with your build. 1st video that TH-cam suggested that seems very doable after the years, probably because I've been interested in the summer at the start of a dry spell. I'm diving deeper into the channel to see whatever progress/ problems you've encountered. Thanks for uploading this.
Thanks for the comment! I have a few videos about my design and install as well as follow ups. Today is June 15 2024 and it has been total problem free! It was installed in august of 2019. Lifetime power is 52.5 megawatt hours! Or 52,500 kilowatt hours! Our power runs around $0.13/kWh so that's $6800 saved so far.
Nice video Neal. Just for comparison; I know of a contractor installed (26) 365W/panel system with 10K battery all Enphase that cost $40K without tax rebate. So, good on you for putting together a great system at a low price!
Wow thanks for the comparison. I'm not sure what a battery setup costs but even if it's a $5k battery that's still a large bill!
Great video, well introduced and presented, Enphase should be paying you. For the gaps between the panels, I would tape the gaps (horizontals first then verticals) and that will eliminate the water/rain falling in between and damage your wood and keep your equipment dry. Tape, like what they use to repair RV roofs (EternaBond). They come in different widths. The gaps actually concentrate the rain falling through and do more damage than an open sky. You may have to add a gutter at the eve, a down spout and drain away from your pad.
Thank you for the comment! If you know anyone at enphase who wants to send me a check let me know!! That's a good idea on the tape, I'll look into that but also not sure how I could reach everything without a manlift or something? Not sure I if i can lay on the panels.
@@NealORussa sheets of plywood would work to distribute your weight over the panel but you need to secure the sheets so they don't slide off and you on them (be careful, use a fall restrain harness). Maybe build a temporary ledge to hold sheets in place. Do the horizontal gaps first then vertical ones second (rain flows downward faster than sideways).
I have been researching doing a solar carport and using tape seems (to me) the best way keep the rain out. Leaving the gaps open will render the carport useless for me (a lot of rain during rainy season).
I would have put a metal roofing on there and did racking rails over the metal roofing. It looks very nice, I may copy this idea for my new house.
Again Neal Thank you for the F/U video. VERY helpful. Our KW cost is the lowest in the country...5 cents. It may take a while to pay my system off.
No problem Hugh! I wasn't able to find much followup videos on the Enphase system, so I was happy to make this one. While it may take a while to pay off, it's fun and the rate could go up in the future! Check out my solar design video if you haven't already ran the calcs on your install.
Fantastic video. Thank you for posting.
I just installed mine about a week ago. And I'm addicted to looking at production and the sky to see if there are clouds. Lol
Thanks for the great comment! It definitely is addicting at first! Enjoy your system! I'm a few months past year 2 and still no issues. I need to make a 2 year follow up video and report on power generation etc. see if there is any detectable panel degradation.
@@NealORussa absolutely. Im interested to hear about it !!
I was just about to search how close the solar estimator program is to actual data. Thanks for the upload!
Thank you for watching! PV Watts is a great tool, but its good to have some real data. I have another video on designing a PV system, so check it out if you haven't already.
Thanks Neal. Great video. Was trying to decide wether to go ahead with the solar as I can only fit 10 panels on the roof. (Live in the UK) where I live we only get 1400 hours of sunshine on average per year. On saying that it would be enough to run some items during the day by setting different start time for the appliances, but the biggest gain for me would be for charging and EV. Although the emphase system costs slightly more, it seems to be a better system.
Thank you for your honest appraisal of your system.
You're welcome Mark, thanks for watching! When I was considering the system I could not find any videos of the phone app or website that shows the power generation so I was happy to show that off. 10 panels isn't much, but is better than nothing! Check out my other videos for how I designed the system, which may help with your project.
The breakdown was great, nice video.
Thanks for the comment and for watching! Hope you can subscribe to catch more!
Hi, thanks for the video, IQ8 has only been released in the Encharge battery. The most recent addition to solar microinverters was the IQ7A.
Thanks for the info! I haven't kept up much with their products after i did the research on my IQ7+'s, but they have been working great so far.
For exposed pressure treated joists, rafters, etc you can get rolls of rubber membrane that has adhesive backing. Just build, then 'peel & stick' before screwing the roof or decking down. I have used Soprema foundation membrane (3 foot wide rolls) which I cut with a box-cutter to the width I wanted. FAR cheaper than the pre-cut membrane 'tape' rolls.
That's a great idea, wish I would have done it before I put the panels on!
Use tanking paint on top of the rafters! In fact, before each post goes in the ground I paint them with the tanking paint also.
Good idea. Thank you!
Doesn’t look like your system is set up for consumption monitoring but I love it on our system. The Current Transformer wiring can travel quite a long way. So maybe it would work for u... thanks again for the great video, cannot get enough Enphase. Next maybe an EV for driving on sunshine!
I decided not to do consumption monitoring, didn't see much benefit for me, meaning I'm going to consume what I'm going to consume... If I want, I can calculate my consumption using the information provided by my utility company. They have a website where i can see the daily kwh delivered to my house and daily kwh I send back to the grid. So using the information from enphase enlighten, I can calculate my consumption with the following equation: Solar Power generated + Power delivered from utility - Power sent back to grid = Consumption. Also, have purchased a Chevy Volt Plugin Hybrid EV, so i wish i had more panels because my solar doesn't cover my 100% of my usage anymore!
Your rafters should be fine they're exposed to very little water and can easily dry after getting wet. Posts will rot faster where the concrete is next to them then they would if you had back filled the hole with gravel. The concrete does not allow air circulation and posts will rot faster then posts surrounded by gravel due to the air space between pieces of gravel. Probably not a huge issue for the posts as the solar panels are shedding most of the water.
Appreciate the comment! I agree there isn't a ton of space between panels for water to get on the rafters, and the posts are somewhat protected by the panels themselves. Thanks for watching!
@@NealORussa That was what caught my eye in your thumbnail (subbed, too!) as I want to protect the evening side of my deck and catch some evening sun with solar panels while doing it. Solar panels are actually cheaper than plywood as there are some re-sellers of commercial panels in my state.
Just need some posts... unistrut & about 1/2 the rafters of a 'regular roof'... what's not to like?
@@Le_Comte_de_Monte_Felin yea that's a good way to make a covered deck! Also if you're in the us make sure to take advantage of the new tax breaks. I think it's back to 30% tax credit on the cost of solar install/materials.
thx for showing the app this detailed!
No problem! I couldn't find any good videos of the app's abilities before i purchased the system, so I am happy to show potential buyers what it has to offer! Just wish it would have came out clearer...
You can also enable the consumption meter to know the energy is consumed! which would help you in reading the utility bill in a better way.
Yes the problem is I would have to have my consumption meter reader device in my main panel which is about 200' through various existing underground conduits to my iqcombiner box where the envoy is located. So it would be difficult to get it all in the app properly. Now I could purchase and wire in a secondary consumption meter but honestly not too worried about it. Thanks for watching!!
Neal, your video was instrumental in my pole barn build/solar rack with Enphase and 18 panels. thank you, Port P.S. the treated lumber will outlast the system. In thirty years should the pole rot you will easily add extensions to the current concrete.
Port thank you so much for the great comment, glad I am able to help! Appreciate your input on the posts too. Enjoy your system!
Excellent video!!!.
I see your peak is around 7.6kWh and is probably because you are using 310w Solar Panels. I just finished the installation at my mother's house last week (in Argentina) but I decided to use 370w solar panels because in reality you only get 80 to 90% of specs, plus they may lose some % over the years, besides it was the same price as a 325w panels.
During a sunny day in summer (is summer in South America), I'm getting 2.4kWh at peak with 8 Panels and IQ7+ (INT version), little over of the actual peak of each microinverter, and yesterday the PV System produced 19.55kW. this is an small system which is more than enough for what she actually use.
PV System is 8 monocrystalline Amerisolar 370w Panels (no the best brand) and 8 IQ7+, 35 degrees inclination (15 is the best for summer) and facing north (0 degree).
Hey thanks for the great comment and make sure to subscribe or check out my other solar videos! You made a good move getting larger panels, would be good to put more power into those inverters! But these did also work out pretty close to the 30' wide dimension I needed behind my shop. Thanks again
Use pour stone to fix your concrete it levels flate and is designed to fix thick or very thin jobs , it looks great nice job
at 20:15 you have 86% of the estimation.
you could add this number ( 86% =^ 14% losses) to your estimation data basis (at 18:00 ) where you put 0% losses.
im not sure if this is the right way, but i guess you can try it as you can change back this number all the time.
Appreciate the thought there. I went ahead and put 14% loss in at 18:00 in the Enlighten website and saved the changes. It didn't immediately update my estimated for 12934 down 14%, but I'll check back with it and see if it changes.
awesome video man. we were paying 400+ here in the winter then I installed an outdoor wood burner for hot water and heat and that dropped the bill down to like 125 in the winter. We are all electric, less hot water from wood burner and winter heat. The pool in the summer cost around $50 a month to run the pump alone. That is the jump we could see when it was in use. I have been looking at solar for about 5 years and have not yet pulled the trigger. I would love to speak to you sometime.
Thanks for the comment! We're all electric here too and I have a pool. It costs a lot to keep that pump running! I also purchased an electric car after I installed my panels, so that has driven up my electric usage. I wish I had more panels! Check out the design video I have to help design your system, then if you'd like you can email me questions at daviesscountytractor@gmail.com.
As for the plastic on the top of the rafters to protect against water, you could try Flex Seal tape.
Im getting a deal on these panels for $59 each. Can't wait
Awesome! The federal tax credit is active again so make sure to take advantage of it!
Absolutely on point. Great!
I appreciate the comment, thanks for watching!
Planning on using Mission Solar and Enphase inverter also.
Nice, its a great setup!

THANK YOU FOR A VERY USEFUL VIDEO.
No problem! Check out my other solar videos for more info on design, installation and yearly updates!
Heh Neil, great video. You covered a lot, and super interesting. One thing though. You mentioned that when you lost utility power for nearly a week that the system still generated power and the envoy updated after utility power was reconnected. Is this not a problem? Solar installations that are grid tied are supposed to automatically monitor for power outages and shut down any solar production back into the grid until power is restored. If you continue to produce power when the grid is out, then something is wrong and your system poses a threat to the safety of utility workers trying to restore power under anti-islanding regulations and requirements, no?
Hey thanks for watching and the comment! I did not lose utility power for a week, i only lost internet for a week. You are correct with the rest of your comment though, the system shuts automatically off when no grid power is detected, so when the power goes out I do not generate solar power.
Thank you for sharing!
Thanks for watching and the comment!
Thanks for posting! I'm considering building a similar structure with solar, but adding a roof below the panels and using the space below as an outdoor covered patio. As this structure would be split between recreational and solar use, I doubt the cost of my structure would qualify for the tax credit. Any insight regarding when a new structure supporting a solar system can be included as part of the tax credit?
I would keep track of your receipts and costs for materials used for your structure and mounting solar panels (posts, beams, mounting rails, electrical, etc). I would include those costs as solar structure costs. The roof sheeting and any items that provide the convenience of making it an recreational space, do not include in your tax credit. When filling out tax form 5695 (www.irs.gov/pub/irs-pdf/f5695.pdf), there's only one line for qualified solar electric property costs, theres not an itemized list that they check. Then carry the final number from 5695 form onto 1040 schedule 3 form (www.irs.gov/pub/irs-pdf/f1040s3.pdf). Note that for 2020 the solar tax credit was 26%, in 2021 it goes down to 22%. The credit is currently set to expire at the end of 2021.
Where you had the leak at the top of the 6x6x4 box and relocated the entry to the side. I would recommend a drip loop -- that's where the wire descends below the box entry point and they rises to the entry. Like a 'p' on its side. Therefor water running down the cables will drip off and not enter the side of the box. Overall, nice job though.
Thanks Bill, definitely a good comment! I wish I would have put a drip loop at that box as well as my conduit entry into the IQ combiner box below the 6x6x4.
What a beautiful dog.
Any inverter clipping? What is the max power ever product by 1 good panel?
Not that i'm aware of. Looking back around june this year on a really good day, one panel got about 256watts. Divide by 240volts = 1.067 amps. The IQ7+ max continuous output is 1.21 amps. So that leaves a 0.14amp buffer or almost 12% before clipping. Panels rarely obtain their stated wattage, which is why you should oversize your "rated" panel for your microinverter. The closer to clipping the better in my opinion.
Great video and info. Like, subbed. Question. Does your local building code consider your solar panel setup the way you have it as a roofing and storage area? For example where I live I'm only allowed 35% of accessory building roofing in my backyard. I'm trying to determine if the panels will take away from this total or if it's not categorized as roofing depending on how it's installled.
Hey thanks for the comment & sub! Our codes do not have regulations for roofing area on a property. I suspect that may be due to impermeable surfaces on your lot, generating excess storm water runoff? If this helps at all, i did not require a building permit since it didn't have sidewalls or a true roof. Only electrical inspection. They said if I put roof panels or sidewall panels on it they would have required building permit and inspections. Maybe you could leave a 2" gap between all the panels and that would suffice?
Get a good durable water proof paint/sealant for the top of those rafters. You could pull the gravel away and paint the bottom of your posts too to help those slow the rot. Pull the gravel, wash the wood and give it ample time to dry, then use a water sealant or paint up to a few inches above the gravel. Seems to me that would go a long way.
Great video. I am not a homeowner yet so I am not watching for the use/purchase reason but for investing in Enphase rather. You have given me some confidence that they have their stuff together. Can you think of any issues you had with Enphase? How about anything that surprised you positively? Any info or input would be greatly appreciated. Thanks!
Just pour some oil around the base of them after oil changes, it's an old trick in some pole buildings some even put something in place to put oil in the hole to prevent rot.
Travis, I didn't see the 2nd part of your comment at first so sorry for the delay! I haven't had any issues with the Enphase system. As I mentioned in the video, I was really surprised that the envoy kept the energy generation info stored for a week without wifi connection. I also like the ability ease of turning it off and on without any new setup, or the fact that after a power outage, it just starts working again when the power returns. I never have had to go mess with any settings. If i was doing another install, i would skip running the power into my garage sub panel, which feeds my main panel, then out to the meter. Instead i would run heavy gauge cable from the panels straight to the house-side of the meter, and put a tie-in there. That way i would stay out of both of my electrical panels. Also, i could construct a much larger system because i wouldn't have been held back by my main panel amperage rating.
When i sized my system, i sized it off my existing house loads. Well, about 6 months after the system was up and running i decided to get an electric car, so now i charge at home off 240v power. So my energy usage has increased substantially. I wish i had more solar panels!
I can make it myself. Just got instructions from Avasva and I'm ready for do it :D
I like the use of strut. What was the savings compared to using rails?
Hey Gary! I don't recall exactly what the cost savings was, but it was a lot! I was looking at ironridge racking, but the unistrut blew them out of the park, in terms of value.
Will you be doing another update on how it's working?
Thanks for the comment! Yes I have a video in the works! Teaser - ⚡️⬆️⬆️⬆️
In order to commission the system with Enphase did you have to purchade the upgrade software or did you hire a local installer to set up the system in the enhase app?
No there was no purchase required. I used the enphase installer toolkit app (separate app from the enphase enlighten app). I had to create another username and password but that's it. Check out my other solar video where I do the full install. I talk about it a little bit.
Are you happy with the Mission Solar Panels? They're priced very well and since they are built in San Antonio I imagine they'll hold up in my Florida heat better than Silfab that evidently are known to overheat.
Hey Craig, I haven't had any issues with the Mission Solar Panels! Its been over 2 years now, they still look great, no visible corrosion on frames, no peeling or anything like that and they still work flawlessly.
So me and another person was curious as to why you you didn't put in a battery system..
Thanks
Hey Crowe! There's two reasons I didn't put in batteries. 1, cost. 2, it requires a more difficult install and well as some more sophisticated transfer switching equipment with the grid at the meter. The location of my meter and electrical panel is in a location that makes it difficult to add this type of equipment (it's behind a cabinet in my mudroom). I believe the new emphase inverter systems are more battery friendly.
suggest to Paint the rafter tops with urethane.
Thanks for the comment!
Very nice and good looking set up. I have 40 LG 330 watt roof mounted panels, Enphase microinverters and monitoring system. We had it installed 5/2019 and it is covering about 90 % of our generation needs here in SE TX, primarily A/C loads 6 months out of the year. I have acreage to retire on in 5 to 6 years and am considering DIY with a ground mounted system, installation of our current roof mounted system was at least 50 % of the cost. Hope they reinstate the 30% tax credit as well. Several people have approached me and asked questions yet still seem skeptical, I sure don't miss the 350 dollar electric bills in the summer and really like seeing a credit balance built up during the shoulder months. Solar to me is a no brainer, David.
Thanks for watching, I always like to hear about other systems! If you decide to DIY make sure to watch my other videos on designing and installing the system. I'd say its definitely a no-brainer on the decision if you can install and save the labor charges and markup on materials. Unfortunately I had to get my system up and running before Jan 1 2020 to get grandfathered in with our utility company for the net metering at $1 for $1 credit on the kwh i send back to the grid.
They haven't announced what they're going to do yet, but there was a law passed in KY that says the utilities can decide what they want to provide as a credit so it might be like they only give 1/2 kwh credit for every 1 kwh you send back. If i modify my system for more panels, they can un-grandfather me as they will set it up as a new net metering account.
@@NealORussa I certainly hope they do not change that 1 for 1 credit, here in TX the utilities currently do same and I have not heard of any plans to change, if that were to happen I may consider using batteries for storage as an alternative option. The technology is advancing and the cost continues to come down, have a good weekend.
Very well done. You're probably underestimating your dollars saved (and thus payback) by not accounting for inflation (price increase) of power over that 20-year span. Also, assuming 0% losses in PVWatts was unrealistic, as soiling and system losses are real. The baseline assumption is 14%, so your production is probably a lot closer to PVWatts' estimate with that baseline assumption.
Very good points! Thanks for the comment!
I'm not sure if I missed something but I didn't see, anywhere in your spread sheets, how much of the power generated is used by you and how much is exported onto the grid, also how much power you buy from the grid during cloudy days or at night.?
Hey thanks for watching! I didn't really mention much on my home's consumption since every home will be different. On average I send power out during the day, and use power from the grid at night. Also, fortunately or unfortunately, I now own an electric car, which I charge daily and it takes 10kwh to charge. My system was designed without that in mind, so I still buy quite a bit of power.
You can purchase a consumption meter from Enphase that monitors how much power your house uses vs how much your system generates. I did not purchase that add-on because it would have been difficult to wire up in my application since i tied into a sub panel in the garage instead of the main house panel. I can calculate my household usage monthly though with the following equation: Monthly System generated power from enphase enlighten app, plus energy bought from power company on bill, minus energy sent back to grid (also shown on monthly bill) equals my home's consumption.
@@NealORussa The envoy that you already have in the combiner box will measure import/export (consumption) power as well as generated power. You just need to put a CT in your main breaker box with a small twisted pair wire to the envoy consumption terminals. Then your Enlighten app will show produced, consumed, net imported, exported and imported updated about every 15 minutes. It doesn't matter weather you feed the generated power into a sub circuit or your main breaker box.
@@jobce1 yes that's correct! Problem is that my array is about 200' from my main panel through 2 other panels and a lot of underground conduit!
@@NealORussa That could be a problem. I thought it was right at the house with the garage on the right hand side.
Thank you for this video. It's super helpful. :)
Thank for for the comment, I'm happy to help! I have a few other solar related videos on my channel if you haven't seen them yet.
Neal: What model Enphase combiner box/software setup did you use?
Hugh, i used the Enphase IQ Combiner 3 (X-IQ-AM1-240-3). As far as software setup, i used the enphase installer toolkit app on my iphone.
Super nice video..ty.
Thanks for the great comment! I have a few other solar videos if you're interested in putting a system together.
Great video awesome breakdown 👏👍
Thanks for the comment!
your envoy should have a cellular backup connection - u should install it. also get a cyberpower battery backups for all your internet equipment. it cleans up the power and should keep it online for a few hours.
Hey, the envoy does not have cellular capability by itself. There is an add-on module to get cellular through AT&T, but you also have to pay for that connection. store.enphase.com/storefront/en-us/cellmodem-m1-1
No reason really to get it, works fine through wifi and it still uploads the data after an internet outage. My internet was recently down again for about 10 days because the county mowing crew ran over my pedestal. Envoy saved all the data and uploaded it when i was finally reconnected! Thanks for watching!
@@NealORussa yea it is an add-on... but yea you should get a small battery backups for your internet. 100% uptime! lol and yea your solar system is quite cheap compared to the retail pricing... about to pull the trigger on a 11.5Kw 30 LG panels with IQ7+ Microinverters and 2 encharge 10 batteries... total cost is about $50k.......
Do you have full 25 years panels and IQ7s warranty if you installed yourself? I think you need to be install by authorized installer to get full warranty from the factory.
You are incorrect. The warranty applies as long as it is installed in accordance with the manufacturers instructions. enphase.com/sites/default/files/2021-10/March-2017-Enphase-microinverter-warranty.pdf
Hi Neal, Just watched both of your videos and the system looks great. I also enjoyed your payback calculations. One thing you didn't factor in on your calculations though, (unless I missed it somewhere) you aren't accounting for price increases from your utility company. I think a good average is 3% per year. I have seen some reports recently of some utilities that are trying to raise their rates as much as 18% in one year! Nice job on the videos.
Thanks so much for the awesome comment! You're right, i didnt take into account the price increases of the utility company in my calculations. That could be another factor showing quicker recovery of costs! I'm planning to get a 2 year review out, not much has changed but will be interesting to see the annual power generation and see if the system has dipped much over the last year due to panel degradation.
I think the plastic sleeve would only serve to collect moisture as it would have holes in it at some point. The water will run from the top of the structure down the top of the beam and potentially into the sleeve. Just a thought.
Neal O'Russa with cell degradation it might be not far off
I love this!

Would You please explain how the system converts what DC voltage to what AC voltage through the Enphsse Converters and where is Your battery backup system or do You have one.....I watched both Your videos and never heard You talk about the electrical principles st all....and was disappointed thst someone as smart as You are negated to explain any of the electrical principles....How Does The System Work Electrically....Good Videos....
Hey Neil, thanks for the comment! To be honest, I'm not 100% sure how the panel converts the sun's energy into DC power. I'm also not sure how each microinverter converts the DC power to AC power. But I do know that each microinverter has an constant 240v output and varying amperage from 0-1.21 amps per microinverter based on how much energy is going into them from the panel. When you string them together in parallel the amperage adds together. So i have 3 strings of 9 panels, where each string can output a max of 10.89 amps. They all add together in the IQ combiner box and I send a maximum of 32.67a at 240v to my subpanel in the garage. I do not have battery backup, i am grid tied with net metering through my utility company. You can also view this video, it has some information on my system and also shows my wiring diagram. th-cam.com/video/DzvRXU_zUWE/w-d-xo.html
@@NealORussa I think the input of DC Voltage from the panels into the Micro Converters comes out as AC Voltage going into the panel breakers, as there are 3 breakers for input for AC Voltage and the EnPhase Converter in the panel with breakers monitors and adjusts the AC Voltage going out to Your Main Electrical Meter where it is put into the grid depending on what time of day it is and if the panels are outputting enough voltage to overcome the grid power.
In any event... I did learn something about micro converters and the difference between optimizers and micro converters, which differentiates between AC and DC Voltages respectively....
Thank You for Your reply and You have a great looking system....Enjoy!!!🤠🤠
@@bigdognance The inverters do all the work. The only thing in the IQ combiner box is the envoy, which does the monitoring and uploads it to the cloud. The system will work without an envoy, it will work with the microinverters standalone. I prefer microinverters vs a single inverter and optimizers because your home run cable from array to inside your building is ac power which is much safer than running high amperage DC power.
@@NealORussa Oh...OK....That is a lot more accurate than my rendition of what was going on....sheese....so You were "sand baggin" on me...lol....You really do know how it works....Thank You for clarification with the additional information. I'm starting to understand how these micro- converters work instead of a string converter....
Do you turn off the system when you need to wash the panels?
Hey there, thanks for the comment! I have never washed the panels. I did some reading about whether or not it was required, and consensus was no, the rain will take care of it. If i were to wash though, i would not turn them off.
Great video Neal! Nice to hear this equipment is running strong for you! I am currently installing almost the same system as a roof top with Enphase IQ7+ inverters and 36 Mission Solar 350w panels.
One quick question as a DIY install did you start up your system with the Enphase Installer app or just go straight to Enlighten. They mention "your installer will setup your homeowner account" ? I can't seem to find the DIY startup link? Thanks Neal
Thanks for watching! I used the app on my iphone called Enphase Installer Toolkit. Then you connect to an Envoy using WiFi Peer to Peer (P2P) aka WiFi Direct. There is a button on the Envoy to turn on a P2P network, then it shows up on your iPhone as an available WiFi connection. Once you connect in your WiFi settings, then you can open the app and connect to your envoy. Once you get to that point it was pretty intuitive. Then you can configure everything and set the WiFi Network & password that the envoy should connect to. I did mention in my installation video that you need to be patient during this process because the Envoy needs to shut down, restart, and reset itself during some of these setup steps. I got antsy when changes didn't take effect immediately and I kept trying to check for updated settings and they weren't updated so I would hard reset the envoy and retry, etc etc. Finally I just changed the settings and waited 10 min or so, and everything worked fine.
Thanks Neal, I appreciate your help! Mark V.
HOA asking
2. Texas licensed Professional Engineer’s seal stamped on the Solar Array Structural Certification paperwork
Know anyone who can provide? I am in Houston area ?
When i was looking, there were a ton of online resources to provide stamped drawings. What are you using for your array structure? If its wood built like mine, you might try a lumber supply house to see if they have in-house design for new homes, etc. They could design plans and stamp them. If you are using Iron-ridge or any other racking supplier, they can provide you with stamped drawings for their system.
@@NealORussa Thanks. Mine is a roof-top on shingles pitched roof and on-grid.
@@xanadunikita7251 what racking or fasteners are you using to secure panels to your roof? I'm sure that manufacturer can supply you with what you need to hoa
@@NealORussa Plan to use Mission Solar with Enphase converter. The dealer/supplier does not this info that HOA requiring. Think Mission Solar manufacturer can supply following ?
2. Texas licensed Professional Engineer’s seal stamped on the Solar Array Structural Certification paperwork
@@xanadunikita7251 if the hoa needs structural information, enphase would not provide that. You need a stamped drawing showing your roof can support the additional load or weight of the solar panels as well as strength of the fasteners holding the panels or racking to the roof. You may want to try a local lumber yard or home builder who can direct you to an architect or engineer to look at your roof and provide stamped calculations showing the roof rafters have sufficient strength.
Would this system still work if my utility company does not support or instal net metering?
Yes it would but any excess unused power would go out to the grid and power the house next door!
Is thete anyway can i have the file you submit to city for permit ? Thanks
Do you live in Daviess County KY? I'd say each city or county has a different permit form to fill out.
@@NealORussa thanks . Just neef the draw file . Cuz i try to build one like you have :)
@@hayabusa3558 shoot me an email and I can send you the excel file for the wiring drawing. Daviesscountytractor@gmail.com
@@NealORussahey I’m interested in the draw file too! Can you send it to me as well! Thanks
How much it costed you?
I don't recall exactly but I think it was around $15k? I have a playlist that contains videos on installation as well as design of this system and it goes over all the details.
any idea if this would work in a 240VAC, 50Hz system?
Francis, I'm not sure these exact inverters would work on 50hz vs the US standard 60hz. A link to the cut sheet says their nominal frequency is 60hz, but note that the part number is "Q7PLUS-72-2-US". They may sell a similar inverter for other markets outside of the US that use 50hz frequencies.
enphase.com/sites/default/files/downloads/support/IQ7-IQ7plus-DS-EN-US.pdf
I did some more digging, here is the international inverter model that runs from 45-55hz. enphase.com/sites/default/files/downloads/support/IQ7-data-sheet-INTL-AU.pdf
Yes, it will work for 240VAC 50Hz, the Microinverter works in a range of 47 - 68 Hz, but you will need the Envoy IQ to change the profile setting when you do the setup (Enphase Installer Toolkit). I will install this in South America where they use 220V 50Hz.
@@federicov362 when are you planning on doing your South America install?
@@FrancisOpokuI will do it at the end of November or December (Argentina). You can download the Enphase Tool kit and register on their website, you can create your array in advance (without microinverters or Envoy) and you can check all the profiles available. I see UK used to have 240v 50Hz, but they are others countries they still use. Selecting 230~240 is not an issue, the microinverter it will always synchronize with the local voltage and it will inject a little more, that way the house will always use the electricity generated from the PV system instead of the grid (higher V and less resistance).
is it free to monitor your system online or through the app?
Hey Francis, yes i should have mentioned that in the video, the app and monitoring website are free and included when you purchase an enphase envoy!
@@NealORussa was the Enphase Installer Toolkit app also free?
Daniel Wiggins yes the installer app was free too! Thanks for watching
Enphase EQ8 Off Grid micro Inverter?
I haven't don't much research on the new iq8's.
Is solar really worth it?
That depends on a lot of factors: your utility rates and net metering agreements, your ability to install yourself, your ability to purchase w/out loan interest, how much sun your region gets, which direction you install your panels, etc. You can check out my other solar video on system design and calculate if its worth it for you. For me, the answer is very much YES!
dig it out and fill with foam
Definitely an option! Thanks for the comment!
2 of us are trying to build ground solar. First one is going against the Town's building board, he's on 3 acres and wants to put up 42 panels. I'm on 6 acres and I want to put up what Neal did, 27 panels. My town limits solar ground based to 120 sq ft.
Wow rough crowd over there. What part of the country is that? I'm not sure why it would be discouraged, especially on a lot of that size. It would be different if you were right in town or something!
@@NealORussa I’m in Wisconsin. The town I live in is not very friendly to solar. They want a design and specs and the hoops they are making me jump through are horrible. I’m trying to DIY to save money and this isn’t helping.
@@bmoulas tandem solar systems will make you a line diagram and pe stamp it. If you need stamped drawings for the wood structure go to a home builders lumber supply house and they usually have an engineer or architect that can draw up plans and stamp them. I would come to them with a sketch already drawn up of what you're thinking to build and they could size the lumber and fasteners.
@@NealORussa They want $400 for a design, seems steep for a ground based install. I wrote them over the weekend, hopefully they reply and maybe I can find out why it's so expensive.
@@bmoulas was that the architect or the electrical engineer at tandem solar? Your other option for structure would be a ground mount system like iron ridge. They will supply you with pe drawings.
Tar around the post.
Good idea!
Brush on some Thompson's water seal done deal
Definitely a good plan, thanks for the comment!
Birds nest are annoying? WTF
Hey Tom, i guess i meant i don't like the bird droppings on the wood structure or on anything i have stored underneath the panels. So in that sense, I guess i mean the bird poop is annoying, not so much the birds themselves...
