This panel can put out close to 100 watts th-cam.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
This is the most detailed installation I’ve ever seen among all other TH-cam videos.
Thanks for sharing the detail installation
Glad it was helpful!
Great install. I am impressed by the accuracy and professionalism of the team. Awesome job.
thanks!
My solar is going in this week, and will also be using Enphase. This video is exceptional and has provided the best explanation of anything I have seen. Thank you so much for making this
Awesome, you are welcome!
How are u liking the system so far ?
Excellent, very clear, detailed, step-by-step video.
Glad it was helpful!
Thank you for this detailed video. RIP to on-site conversations like normal, but it was worth it!! :)
Currently, I have not been able to build a solar panel system like this, but this video really inspires me to stay motivated. Thanks. YuTanBu.
You can do it!
Excellent! Beautifully done. Thanks for your attention to detail.
My pleasure!
Excellent Video. Looking in to going Solar. Just doing my homework.
Thank you for sharing! 🙏 Great work!
LOL @ Minute 13:19. Thanks for leaving that in the video. It's encouraging to see that this happens to other people as well. 😀
This is our system in Colorado Springs:
(8) 325W Solar World Panels (Model: Sunmodule SW 325 XL Mono)
(8) Solar Edge Optimizers (Model: P400)
(1) Solar Edge Inverter (Model: SE3000A-US)
Enjoy your system!
nice setup!
Thanks for sharing such wonderful video, it is very clean and well detailed. All steps are very understandable.
Glad it was helpful!
Excellent video, this makes things look very doable as far as installing the array. Years from now when i have the $$ to install a system i hope to install the array myself then work with an electrician to setup the connections.
Thank you for sharing 🥰 it helped me design a 60 kw grid tie solar power system.
That is awesome!
Great video and good work by those guys. Thank you.
Glad you enjoyed it, thanks
Awesome video man! Keep doing more solar install videos like that. Thank you
thanks! more videos coming.
@@SolarEngineering and hi Guys hfy
Least you tied off. That's the smart thing to do which means I undoubtedly would've "forgotten it" cause man what a pain! Both ways. Excellent video quality work
thanks!
great video. I just put up 31 panels IQ7+. I wish I saw this before hand. My roof was twice a steep
I guess it was tough to install panels, glad you managed it!
31, wow! Pretty big system
The tools and equipment were so professional and efficient..do avideo on tools too
Very nice I'm sure you'll love it for years to come
Great presentation. Thank you for your time and effort to make this video and share it with us. Greetings from Croatia.
glad it was helpful!
Great installation. Great working
Thank you for this wonderful information,I have learnt a lot.
Хорошая работа, мужики! Профессионально 👍🏻
спасибо
Beautiful installation! shows a lot of experience. In my country, we can not do grid tie systems unfortunately! We do only off-grid and hybrid systems! And you dont need a permit to install PV modules on your roof 😀
thanks for the kind feedback. You are lucky that permits are not needed. It's saving a lot of time.

Only one bolt to hold inverters to the rails? No hurricanes or bad weather there huh? 😂
Great video! Very comprehensive. Love the commentary on music selection.
Чувак, это самое крутое и понятное видео по установке панелей из всех ! Спасибо!
спасибо за отзыв!
Great video, thanks!
I am really grateful to you, this video help me about installation.
you are welcome, glad it was helpful!
Very informative video! Should invest in a rafter finding guage. So if you miss the first Time you are guaranteed to hit the second time. Also, The iq7+ can total 13 on one branch circuit. Not 12. That's would be the iq7x.
thanks for correction
I found your work so useful. I will love that you should invite me to come and lean more
This video was great Thankyou for it.
Glad it was helpful!
Great setup
Buena pinta saludos desde la sierra de madrid españa
man, you are the best! thank you very much sir
you are welcome. thanks for the feedback.
I love your accent. Thanks for the amazing video!!
Wow, thank you!
You should do a video on Troubleshooting Enphase Microinverters. Great video BTW!
do you have any particular issue in mind with microinverters?
Nice concise installation video. Thanks!
Glad it was helpful!
Thank you for sharing this great video!
Thanks for sharing comrade!
My pleasure.
This guy has good music advice
Great job 👏
Thank you!
Great overview! That being said, i hate grid tie. No power at night or when grid down.
With Net Energy Metering, the grid acts (economically speaking) like a battery. Battery backup would make a solar system of this size twice as expensive and the battery would be rarely used, therefore making ROI half as good.
@@lagarto7156 A Battery would be use every day and also at night for taking cheap rate grid power. If you are out during the day then you come home to a full battery and use your own energy in the evening. Batteries can also be islanded for blackouts.
WOW, That roof is SHOT. Should have replaced before the solar. Plus foam insulation under the roof in the rafters is a bad idea. But.... The solar install part of the video is great!
Thanks for sharing this video
My pleasure
Amazing
Great video thanks
Glad you enjoyed it
This is the best video I have seen so far on a shingle roof grid-tie solar installation. This was so informative. Thanks.
Very helpful
Very insightful
thanks!
Спасибо за понятный английский язык, с четкими тонами и паузами. Удачи

I finished a 58kwp system a few weeks ago. 128, 455W panels. It was a nightmare finding the rafters. I don't know how the roof was build, but the rafters seemed to be in different places everywhere😂 the rafter was built with just 18mm wide poles so that made it even harder to find them.
The tiles were pressed stone (dont know what its called in english) so we had to predrill every hole we made so we would not break the tiles.
Its hard on the roof.
I also am an PV installer
luca did you do this yourself? I am looking to do 58 panels and have been researching some people I can chat with along the way to make sure I do it correctly
@@shanegrant8075 So you are looking for someone to blame when you screw it up?
Bosch Wallscanner D-tech 150 thing works well see the rafter on the LCD screen. Never had it fail me lot better than using a hammer damaging the shingles.
Hi, guys you doing great job and video,
I have a question here, what is box attached Micran daughter ip7 and what his function? Thanks
great job done by team i have aiiso work with dear mens to get eassy instolation for time management i reqaver such new things to developed thanks soon
Good step by step! . But as installer myself I can’t move at this pace lol. Me n my crew be jamming . 3 guys 16panels 2.5 hours .
Good comment! But as a possible future client I am worried that you are not mentioning the quality you provide “lol”
@@Votoyar that’s your opinion! I’ve installed 11 years and still going and make sure all my mounts are sealed and the entire system is flawless! “Thanks for your input “ “lol”
@@BadInfluence808 that has to be mentioned in your first comment, along with the speed. Hope you are not prioritising the speed over quality just like you did here in the comments.
@@Votoyar me and my team are clearly professionals as you’re just a skecptic! We know to install with speed and quality ! It’s ok if you can’t wrap your head around that its a bit much for you 😂 but we will continue to work like we normally do and put out fast quality installs. If you want, come to Hawaii and see for yourself ! Have a good one ! 😂😂😂
@@BadInfluence808 I really can’t wrap my head around that and it is a bit much for me. Have a good one too.
Greetings, and first of all thanks for sharing, my question is how much was the total for this project and if you are thinking of using batteries for when there is no sun?
I just helped with this project, so I don't know how much owner paid for the system. My rough estimate that materials did cost about $6000.
I have my own system with batteries:
check this 1st: th-cam.com/video/XpPdbo1LXEg/w-d-xo.html
and then I upgraded inverter: th-cam.com/video/Q9hmyFyQO84/w-d-xo.html
Thanks for making and sharing this. A great demonstration of the installation project - it answered a lot of questions.
One thing was odd to me. Did you use EMT conduit on the roof to run the power to the garage? I'd have expected RMT or PVC.
EMT is pretty standard on roofs. PVC will expand and contract a lot on a roof leading to breakage. If you mean RMC as RMT then it's overkill.
21:07 Those block under the piping on the back side of the roof could cause water to back up under the shingles and eventually cause leaks in the roof. In fact, all that piping should really be going through the attic and not over the roof..
Wow man, great jod!!
I'm electrician here in Brazil and work with solar panel. The instalacion is different here. The panels are too big too with power to 665 wats and 49 volts continous courrent
Thanks, curious what is the weight of the 665 panel, must be around 30-35Kg
@@SolarEngineeringyes, and there are panels with bifacial technology with two glasses. from 35 to 40 kg
Very good 👍👍👍👍👍
Those shingles are in bad shape I would have had the roof replaced.
Great Video! Very informative when you know little about Solar. Just 1 question: Does the panel that your Micro-inverters connect to have a neutral (White wire) and where does it come from? I thought that the Inverters only had 2 hot wires (Red/Black). When the feed came from the inverter tie panel where the breakers were connected there was only the 2 Hot wires. When the wires came into the main circuit panel it seemed to be a 3rd wire (a white one)?
Thanks.
From the roof, only 3 wires (2 hots red/black + ground), go down into the combiner box, then from the combiner box 4 wires go into the electrical panel.
Hey, great video very helpful just try to cut it do to segments and what software do you use to show the panel layout at the beginning. Thank you
software I used was just an image editor.
That’s hilarious, I was a lead installing solar and I always had music and specific genres for different hoods but for some reason 90% of the time I had neighbors barking when I played The Beatles…..
I am mounting the solar panels on a barn roof that is 180 feet away from the house due to roof issues on the house. Your installation is exactly what I am planning so given that, would you mount the combiner box at the barn location or would you run the panel wires to the house and mount the combiner next to the House disconnect and circuit breaker panel? Thank you and I concur, this is one of the few videos with an incredible level of detail, great job!!
Hi, if you are going to have 2 strings from roof to combiner box, then mount it at the panels side (you'll need to run less wires). If you are going to have 1 string, then you could mount at any side.
Also it's recommended to mount combiner box at shade.
Very good, and yes I will. I can very easily mount the combiner box in the barn just as in your application you mounted it in the garage, one more question please. Then given as similar system what size wire would I need to make a 120 foot run from the barn to the main disconnect next to the grid tie connection? thank you for your response
@@TheTiffbobby NEC recommends that voltage drop should not exceed 5%.
Enphase - 2% (raise/drop).
With 10 awg you'll have 2.73% voltage drop, most likely it's going to work properly.
But to be on a safe side - I'd use 8 awg conductors, then v drop going to be 1.79%
@@TheTiffbobby may be I should add, that I did quick calculations and it needs to be verified.
Excellent, I have an 8-3 gauge already buried that goes to the barn which I can use for the solar. I appreciate your help, wishing you guys were in Kansas City, you would have a solar install job :). All I have talked to or I should say have been able to talk to are sales reps with know technical experience such as yours, thanks again I will be following your page.
it's the best video on microinverter based solar installation. What brand of panel mounting railing did you guys use? Thank you
as far as I remember it was ironridge XR-10.
and thanks for the feedback
Awesome
thanks!
Love the details.
Any app for the designs? I mean the solar panel simulation
yeah, you can use:
1. opensolar.com - you can try multiple panels/inverters and try it on the roof
2. lyrasolar.com - this will help you to generate package to get permits
It'd be nice if you can post the full list of the hardware and where to get them. Thanks
@austin I work in operations for a solar company and have access to pricing under $2.70 per watt, all the way down to $2 a watt (all depends on what the home needs to safely install a system) with full 25 year labor warranties and production guarantees. Doing it yourself will probably cost around the same maybe a little less but will take longer in most cases
@@chrislacascia4547 I'm interested
Please text ASAP so I can delete my number off of TH-cam 😂
Thanks for sharing good job, what software did you use to design the layout
Hi, you can use www.opensolar.com/ to place panels (free software), or lyrasolar.com to create permit package (~ $80 for package)
Funny to see those kind of roof.. we do not even consider those tiles for our chickens coop.
Important note: if shingles are not straight and crooked, use a string chalk line. Also, caulk the flashings as well as the comp for maximum reassurance. Also for the lags, make sure it’s tight but that the washer doesn’t bust. To be continued as I’m on the first few minutes of this install lol
Side note, im a Milwaukee guy and fuel impacts and drills get the job done just a little bit faster with less effort lol
The fact he said measure from the edge 36 inches means that they care about code and the what the plans dictate that they got permitted for. As well as the height of the rail. But sometimes roofs dip and wave with the integrity of it, so putting all the rails at 2 inches, sometimes does not work out as you will have a “wave” in the panel levelenss. I’ve learned it’s best to level with a rail across all rails and match the middle rails to the bottom and top rails.
They put their micro inverters above the rail, I’ve always put it on the bottom side facing down as the distance from the top rail and where the panel ends can sometimes become a problem if the layout and rail allocation is not correct
Side not again, you can tell about the roof integrity that it’s not the best nor the worst. You can hear all the grains breaking off the compilation shingles themselves and when prying it up, it took no effort. Important to know if you plan on re roofing your house before you put solar on it.
When putting the termination caps on I like to maybe take a little bit of the Omni/Q cable insulation off so you can actually separate the red and black wire to go into the allocated places in the termination cap, separating them, closing the circuit
The rails are supposed to sit on top of the L foots. It tells you in the instructions the attachments come with.
Nice video. What is the software you are usig during panel layout?
Hi, thanks.
I'm just using an online image editor. Took pictures from google earth, a picture of the panel, and joined it together.
the editor that I'm using - canva.com
So at the junction boxes up at the array there is no N connections? Would it be the same for q.peak 480 watt panels using q8A micro inverters? Just the two sets of hot legs from the arrays. Also was that ground a #12 THHN? Also the ground wire on the arrays, all you need to do is ground the racks and then connect to ground wire ran through conduit?
That's correct, no neutral on the roof. The ground on the roof is bare copper (don't remember AWG maybe even 8), from the roof junction box to the panel - 10 AWG THHN.
And yes IQ8A is a good choice for 480W panel.
Do you really need the micro inverters on each panel if going with the sol ark inverter (looks like you switched to that in later video)?
there 2 types of inverters: microinverters and string and only one type is used at the same time.
Enphase in this video is microinverters, Solark - string inverter.
This video is not my system, it's still using microinverters.
What program are you using to design the panels on the roof ?
Hi, thanks.
I'm just using an online image editor. Took pictures from google earth, a picture of the panel, and joined it together.
the editor that I'm using - canva.com
Where did the neutral come from - Didn't see any white wires on the roof from the Enphase converters. Looks like you combined the grounds and call that a neutral? Thanks in advance for help. Great video
Neutral is going from the electrical panel into Enphase combiner box only, microinverters produce 240V and don't require a neutral wire.
From Enphase to the roof going 5 wires (2 pairs of hot legs and grounding wire)
I liked it all except wire nuts at 23:35 I am thinking more stronger screw connection would be better.
umm, I like a screws connection as well (making it in my SolArk setup). But there on a roof I feel that nuts will do its job as well.
I am waiting (so far 2 months) for the installtion of a 4.8Kw system using Qcell G10 (400watt) panels with the Enphase IQ8m microinverters. And it should be using the racking that includes flashing under the shingles. The is estmated to provide 135 percent of electrical needs. Tucson, AZ has good regular access to sunlight. However, my installation isn't expected to happen for 2 more months. Choosing a reliable solar panel company is not a slam-dunk since we have never done it before.
I can get it done for you
Invest in batteries it does make a difference.
What is your torque setting when installing the end clamps and mid clamps to each solar panel?
10 ft-lbs
Hi, Amazing video,. which PV Planning application where you using on this video?
Hi, thanks.
I'm just using an online image editor. Took pictures from google earth, a picture of the panel, and joined it together.
editor that I'm using - canva.com
What tool did you use in Google Maps to plan the placement of the panels?
that was just image editor canva.com
Cool stuff! Doesn't copper wire oxidize on air and due to precipitation?
thanks! it's allowed to run bare 6AWG outside.
Sweet. Now they have to remove all of it in 2 years to replace that roof. Haha
I worry that steel conduit will not hold up in the weather?
How do you prevent islanding with that system? The 20 amp breaker appears to feed directly into the panel.
EMT conduit is zinc coated, so it's ok to install exterior.
Enphase microinverters will automatically shut down when grid power is off.
can you pass inspection with wood blocks supporting conduit? Or do you need to buy something like unirac conduit mount?
so far inspectors didn't have any issues
Is this south facing? Hard to tell from surrounding houses, etc. Thanks. This is just the size I am studying up on to do.
SE
sir can this work well?
power goes into the inverter then pull the power cable into the mcb on the far right then into the main source a
Lvd goes to the 48v relay to trigger the relay
Then the AC inverter goes to the relay via hole no
Pull the cable from the MCB AC inverter output to the contractor so that the load doesn't pass through the relay then enters it into the ATS source B
What guage wires did you use to connect the arrays together and to the electrical panel?
20 amp breaker. 12 AGW should be the size. Great video btw.
every thing looks great but there is a shadow of tree on the panel which might reduce the power generated from the panel.
Micro inverters do not suffer from shadows bringing down the power produced. Shadows only affect the panels they are on, and do not bring down the whole array when you use micro inverters.
I assume the sensor you referred to is to measure production correct? 25:12. What about if you want to measure consumption, would you need to put a sensor like that on the main panel and what is the cost of something like that?
that's correct, this CT sensor measures total array power production.
For consumption here is pretty good monitor: amzn.to/3QFxzWp
I did review for 1st generation of it: th-cam.com/video/lZz69xkkIOg/w-d-xo.html
Great video! What is the figure that particular installation cost for the home owner? How many Watts total was that system?
System is 5600W. Installers charge about $3.5/watt (price for Bay Area, CA).
Oh man, the granules are loose on that shingle. How long before they need to be replaced? That solar work would need to be redone/reinstalled in less than 10 years due to the roof replacement.
I was speaking with a solar installer in northern Illinois, and I may have misunderstood, but I thought he said they wire from the central inverter directly to the smartmeter all on the outside of the house, such that then there's no separate wiring from the inverter to the main breaker panel. He said the main breaker panel in the house is never touched. I am right that it can be wired that way?
Sounds like Line side tap. Yes, it can be wired like that.
What app are you using to design the pv space on the roof?
it was just image editing software.
You could use lyrasolar.com/ to generate permit package.
Which software did you use to design the PV module layout?
Hi, you can use www.opensolar.com/ to place panels (free software), or lyrasolar.com to create permit package (~ $80 for package)
Hello, the installation is very good. How much did it cost with installation included?
The system is 5600W. Installers charge about $3.5/watt (price for Bay Area, CA).
great video! One of the best out there! Q cells are such ugly panels.
thanks!
