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.
Happy to see you back up! Missed you and your videos, I am always checking your channel for new vids. May the Almighty God, strengthening and uphold you and all that is yours, Amen.
Alt E store is great. Bought my first set of panels from you guys last year and picked them up. Need to make another order soon and expand my system :)
Thank you so much. You are clear and direct. I have 2 panels in my 40 panel array that show 2/3 output, so I want to check the diodes. The panels are under warranty, but the problem is that new panels on the market are larger and will not fit in the array, so replacement is not a simple option. Unlike yours, my panel junction boxes are filled with a clear rubber-like dielectric packing. I'll need to deal with that.
Thanks for posting. Deanna and I are looking forward to installing our 48 volt system that we purchased from altE. Today we purchased an Absolyte GX AGM Battery Bank (48 volt, 2000 amp hour)... things are getting exciting!
OL = Out of limit or outer limit Everything between the upper and lower limit can you see the digit out of them OL. Over Load sounds also good but is the load to high you’ll never see again any OL 🤣
Hi Amy, thank you for this video...If the module sun side exposed direct to the sun, it would probably give a voltage close to its rating...Will it indicate reliably a bad diode as well?
Hi Amy from Australia, Loved your Vizsla "Elsie" and Video, I have a problem that has me stumped, my panel (150w) is similar to the one you show with junction box "While in the sun", my panel has no power from the leads, but in the junction box it measures 10.8v from center to either side outer terminals. I followed your test on the diode setting and it gives 1196 at the leads and test on the diodes shows 487 so it's testing like it should be ok, but no voltage in the sun, love to hear your thoughts... Kind regards Dave
I liked the presentation. Though I'm going to dig into it further. I have 9 solar panels producing 2/3 energy (KWH). They are connected to EnPhase M215 inverters. Using EnLighten Manger I see the following: Bad Panels: 17 V DC, 6 A DC. Good Panels 26 V DC, 6 A DC. The panels are typical 60 cell panels, with three 20 cell strings. I can assume no juice is coming from one of strings. Sound like a diode issue? Or could it be a faulty string? Since the inverter numbers are under load, do I have to take one down and test it. Thanks -Kurt
I’ve got an array of JA Solar “smart” solar panels. They have the SolarEdge optimisers built into them. Lately one of the panels is producing only 25-50% of the output of the neighbouring panels after two years of operation. So I inspected, cleaned it, and it didn’t fix it. My best guess is that one of the bypass diodes is passing current probably due to an open circuit fault in the cell string. Hopefully it can be replaced under warranty. My big fear is that the bypass diodes fail under sustained loads in summer time. The cross sectional area of those diode legs are far smaller than the cross sectional area of the cables connected to terminals 1 and 3, and yet they are supposed to pass the current for the entire solar string (maybe 20+ amps).
At 02:54 mm:ss, this statement, "OVERLOAD" is incorrect. When a DVOM meter displays 'O.L.', it means the measured value of the circuit currently under test, is 'OUT-OF-LIMITS' for the selected meter display RANGE. PLEASE SHARE THIS.
I purchased Rich Solar Panels, 190 W. I tested it today using a Watt meter {While connected to a charge controller, and battery bank}. From your video, you informed us that is incorrect! Your video was great, and very informative. I have a Fluke 87, so I can test it the same way you did with Short Circuit Current, and Open Circuit Voltage. The only thing that worries me now, is that while testing under load, and partially shading my panel, (With one hand), the current generated dropped by 50%. I decided to use a broom to shade the panel, and it dropped the voltage from 8.5V to 1.5 Volts. I am wondering, could a diode be bad, or maybe not enough diodes in the Solar Panel circuit? Is that what determines the difference in cost of Retail sales of Solar Panels?
The low starting voltage of 8.5V sounds like a bad diode to me. Then with shading down to 1.5V, it sounds like there is no path for the current to go, again pointing to the diodes.
I have four 100W panels connected in parallel coming off the roof of my RV into a Schneider C-40 controller. All panels are rated at 17.6V and 5.6A. I read 18v across the wires coming off the roof array, but when I connect to the controller I get a reduction down to 7.5V across the input terminals. Voltage across the controller battery terminals is 13.5V. I get ZERO amps reporting to my battery pack during full sun. Does this sound like a bad diode situation?
Hi Ive 35 volts across both sets of panels but no current. Used to work fine .I cleaned them with car wash wax .No amps since! Ill wash them again without wax. Any suggestions
Hi, nice briefing, i have 3 solar panel, every solar panel have 3 diod, and showing different reading on multimeter, but 1 plate diod show no reading or zero reading, what does it means?
6.1.22 Thanks for making the video. Question: I have 2 used panels where one of the PV wire pulled out. When I open the junction box on the panel the junction boxes are filled with a white rubber-like filling. What is this stuff and where can I get some? What I did to fix was to solder a PV wire to the brass looking tang. Seams to be working. Showing 42 volt and 9amp. So I am guessing the diodes are ok. Thanks again.
From your description it sounds like some kind of sprayed electrical insulation filling. If the panel wiring seems to be secure and functioning, I wouldn't worry about it.
I have RICH SOLAR 100 Watt 12 Volt Polycrystalline Solar Panel. I had a reverse Voltage and blew a diode. My eyes cannot see the numbers on diode. Can you tell me what diode I can get to fix panel?
Hi there. What if it’s the other way around? My panel is reading voc of 22.32v at full sun, but my isc is at 1.5amps only instead of somewhere at 7amps, what could be the problem of my solar 120W panel? Hope you could help me. Thanks
I just tried that with a string of 4 220w used panels I have the diodes that were working made the whole string seem good. But they would drop production down to 32 watts in series with light shading. but I would get 180 watts out of a single panel. took the back panel off and 3 out of the 4 solar panels had 4 bad diodes and 2 good diodes making them seem ok. but holy crap they lost production if I only covered a little bit of the panel. now I have to figure out how to replace the diodes.
Water got into the junction box (like the ones you have open) on the back of a few of my solar panels. There seems to be a bit of rusty water around the screws. The diodes look dry. Can I dry those screws and still have the junction box work?
Within reason, all electric contacts can be cleaned. You can use some acidic solution. like vinegar, lemon juice or mustard. Thinking about "stuff" you probably have around the house. Off course other commercial grade electronics cleaning products can also be used. Mechanical cleaning with sand paper, scraping, etc. Will provide clean and absolutely functional in no time! With this said AFTER cleaning make sure to "seal" the contacts with dielectric grease or similar. Protected contacts will last ages... Make sure that any water that gets into the box has a way to get out! ;-)
Hi, I have an issue with a 340W ( Vmp 32 V, Imp 10A, Voc 40V, Isc 10A.6) mono solar panel I recently bought. The voltage reading without load is fine, but without load I can never get more than 1.8A. As soon as it's connected to my microinverter or my off-grid inverter, the current goes down to 0.1/0.3 A and it never makes more than 11W. No shade, no visible damage, nothing. I already change the MC4 connectors, check voltage continuity in the cables, changes cable, tested the bypass diodes, temporary replaced the bypass diodes, and still nothing. Always the same 5-11W power production. What could it be? I run out of ideas..... Thanks!!
Thanks for the new videos and the old ones too! I’m glad you have a wear house in PR but it’s has few items available, try having more stock and do some fb ads there is a lot of people that want to build backup sistema and there are few that bring those items to the island and most are focused in full off grid or grid tied.
Thank you so much for your feedback. We've been stocking our most requested items in PR since just after Hurricane Maria. Over the years we've adjusted what we carry there, versus what we can easily and cheaply ship from the mainland. On island, we have hybrid inverters for grid tied battery backup (our most requested system) and off-grid inverters, charge controllers, and batteries. We tried stocking solar panels there, but they were not selling well, as many people are adding battery backup to their existing grid tied solar system and didn't need more panels. So we recently stopped carrying them there, but can still ship them as needed. We are constantly adjusting our stock based on need. We also do Facebook ads, but it sounds like not enough, so we will look at increasing those.
Unfortunately, when I open the back of my panel case, its been filled in with that white silicone stuff, so can't even get get direct access to test or even replace if needed, without attempting to dig out all the goo!
Ohms test is ok with Shottky diodes. Will not give reliable results with regular pn junction diodes as some ohm meters use less than .6V which will not forward bias the tested diode.
When your measuring resistance I see that you cross the contacts. Red to -, and black to +. When I test my panel like that it is in an "open" position. I have to keep black on - and red on + like when we test on the diode setting. Why do you need to switch them? Why do I not need to switch them?
What do you look for if your solar was working fine. Then suddenly stopped charging? Charge controller says panel not there. Not reading anything from the panel. System is just a Furrion 50 watt Battery maintainer. Battery is fine at 12.8 volts. Was driving from Denver to Seattle and the 12 volt fridge was off after 10 hours of driving. Noticed it when I stopped to make lunch at a rest stop. Fridge was not cold. Must have been off for hours. Normally don't Have issues driving 12 hours with the 12volt fridge on.
Why do some people talk about a shaded panel reducing wattage of an entire array if the panels are equipped with bypass diodes? Is this something regarding older panels that perhaps did not come with bypass diodes?
Please, anybody can help me to explain what is happening. I have a 24V setup with 16 lithium battery, a BMS balancer JKONG and a Powland Inver. My app show a 75% charge,432ah in the battery but the Voltage is down to 23v. ... The inverter is reading 22,1v and prepare to shoot down. Why??
Sorry I have watched this twice and still confused as to if these diodes where good or bad, you might have thought that you said this is good and working but I didn't hear it. Maybe if you can explain simply and to the point in the comments explanation then others can also understand if also confused. Thanks...
Just one thing that's mentioned in this video I noted. She says OL is Over Load. This is wrong. OL means Open Loop ie open circuit or no circuit connection. Otherwise not a bad video for a novice.

U give a clear practical explanation
No one give in the others channels
Happy to learning through the instructor
Excellent video! Extremely easy to understand, love the explanation with the multimeter on the screen. Thank you!
Thank you for this channel. I’m just trying to learn about solar. You make it understandable.

Hi Amy
thanks for another good presentation, stay strong and God bless
Thanks Amy another great vid, SOLAR QUEEN strikes again.
Really, really nice job. Great video - thanks!
Hi Amy from India, Loved your Teaching. Take care of your Dog. Gods Blessings
Please make more of these videos!
Thanks for sharing informative material
Hi teacher thank you for this good video I love this so much
well explained! thankyou.
Helpful thanks Amy
Very helpful. Thanks
Great videos! Thanks
ONLY Video on YT that explains what a low voltage from a panel means. Voltage lower than output rating, = Bad Diode....check that first
Love the idea
Thank you!
Thanks for this video
Great video, thx! Hope your breathing gets better : )
Thank you for explain
Fun fact... OL stands for Open Loop or Open Load.
True in this case, can be over load in a voltage on some meters
Like Chris said, can also mean out of range.
I learned it means open load
OL = Out of limit or outer limit
Everything between the upper and lower limit can you see the digit out of them OL.
Over Load sounds also good but is the load to high you’ll never see again any OL 🤣
thank you very helpful
Elsie is a doll !!

What about the panel having more diodes parallel attached... how to check them
If you can access them, you can measure them one by one as shown in the video.
The best way, to est a diode, is to take it out, do the measuring.
When your measuring resistance I see that you cross the contacts. Red to -, and black to +. When I test my panel like that it is in an "open" position. I have to keep black on - and red on + like when we test on the diode setting. Why do you need to switch them? Why do I not need to switch them?
You need to check in both directions. OL in one and something less in the other.
What do you look for if your solar was working fine. Then suddenly stopped charging? Charge controller says panel not there. Not reading anything from the panel. System is just a Furrion 50 watt Battery maintainer. Battery is fine at 12.8 volts.

Normally don't Have issues driving 12 hours with the 12volt fridge on.
what if the voltage is good but amperage. e.g. Expect 4.91, reading .8
Why do some people talk about a shaded panel reducing wattage of an entire array if the panels are equipped with bypass diodes? Is this something regarding older panels that perhaps did not come with bypass diodes?
Yes, newer panels have a lot of tricks to avoid resisting the current in their string including multiple bypass diodes and split-cell designs
Please, anybody can help me to explain what is happening. I have a 24V setup with 16 lithium battery, a BMS balancer JKONG and a Powland Inver. My app show a 75% charge,432ah in the battery but the Voltage is down to 23v. ... The inverter is reading 22,1v and prepare to shoot down. Why??

Mu panel's diodes are not showing any voltage drop. They are showing 0.000 on forward biased connection
Please guide me
