Do you have solar panels with broken glass? Do you know how to test and determine your panels are still functional? Check out how I test and fix my panels.

You should also check the short circuit current with a clamp meter. UNI-T make a cheap one with a 2A and 20A DC scale.

Agreed… Voltage is not the measure you want, you want to know how many watts you can get. Voltage can remain constant across a wide range of efficiency, and you’d need a before and after calculation of watts on the seal to really tell if it degraded performance.

Lol, true. I was not too concerned about max voltage as they were broken. I just wanted to be sure I got relatively the same voltage as I would expect for 3 diodes, pointed at the ground, with a fool standing right in front of it :) I got a decent voltage.

Hi. Great work, great video. Question: Aceylic paint, transparent, UV resistant and: matt or gloss? Thanks! Cheers!

I am using this: www.walmart.com/ip/Clear-Rust-Oleum-American-Accents-2X-Ultra-Cover-Matte-Spray-Paint-12-oz/965292579?athbdg=L1600&from=/search It is a Clear Coat - Matte (UV Resistant / Anit-Yellowing) spray paint. I am not sure if I remember if it is Acrylic or Polypropylene ... the product does not say. It claims to be a clear coat / hardened shield against damage. That sounds like acrylic to me. But I just don't remember what the can said. The current online product information is not very helpful. I hope that answers your questions. Thank you for watching, and commenting :)

Is it only glass over the pv cells or is it likely that it's laminated with plastic somehow?

@badideametals 9 ай бұрын

That may come down to the manufacturer’s specifications. Most panels that I have seen have a sort of tempered glass directly over the pv cells.

@SamsDIY 5 ай бұрын

I've seen a lot, and most monofacial panels are glass on front, plastic laminate on back. On bifacial panels it's tempered glass on glass with PV cells sandwiched between them.

Also did it make the solar panel any sturdier? I've found that after the solar panel glass breaks, it loses a lot of it's structural integrity, and starts to bend and warp a bit. Also moving the panels makes them sound like rice crispies. I'm curious if this works, but is not strong enough to hold up when moved or flexed at all. Let me know what you think!

I am putting them up in the next week. I got held up with weather in the spring and I have been working on a side project not related to the channel. They are going up this week, the battery for them will be built the week or two following, and last touches will be done last. There will be a video series for all of this. Sorry for the delay.

Will this coating get uv damage (yellowing) over time and reduce the panel efficiency? Does it withstand elements without peeling?

@badideametals 2 жыл бұрын

Both good questions. The cans say they are good against UV… but I have tested them out long term. The coating is like patch work on your car’s clear coat. But I will do a follow up after it has been out in the summer heat and sun.

I got a 200w panel that was used as a football by the delivery company, the seller honoured the trade by sending a replacement and let me keep the cracked one as well so I figured I might as well put it to good use. Will be waiting to see your update and future videos ,subscribed. Cheers!

:) Sweet! Thanks ... Have you checked the open voltage of the panel? Good luck treating the panel and getting it running. My battery is almost ready for re-assembly and the panels are not yet up due to the amount of snow around my shed. I will be putting up the frame just after the channel anniversary in April. I have a few videos coming focusing on the panels and batteries. Thanks again for checking this video out.

@@badideametals I finally managed to put up the panel after following this method. I went with a product called Pastikote, matt finish as well. Panel is rated at 27VOC, I got a 25.89V reading before and stayed within 24V range (variable decimals) after. This was on a clear sunny day,however the sun is still sort of on the low angle at this time of the year so hopefully it will hold till June and if possible fingers crossed perform better. Thank you once again.

I should do a follow up video. I had to detach them from the charge controller as the controller and battery were not compatible with each other (no fault to the panels) ... I have the panels mounted, have had them up over the winter... I will do a quick update and check the voltage range to see how they have held up. But the quick answer, they were holding up just fine since I last checked.

I just put some panels on my garage roof and knowing the little DARLINGS around me will see them as a target,,Would it be ok to put clear perspex sheet over them ?

@badideametals 2 жыл бұрын

I don’t see why not. Sun angle is very important for panel efficiency. If putting a coating over the panel causes light to get diverted or refract, it could lower your efficiency. But to help protect the glass, … I would consider doing it too.

Would you be able to apply this with the panel still mounted at an angle on the roof, or does it need to be flat?

@badideametals 2 жыл бұрын

Great question! It depends how thick the applications are. If it runs a little, you may get an uneven coat, but to be honest, if you are trying to fix cracks, sealed glass is better then broken. I would rather have the glass sealed if it means I would have drips or an uneven coat myself. That said, if you can apply the coats in thin sheets, you won’t have an issue.

Checking panel voltage makes no sense. The voltage will be up there as soon as there is daylight. You should check the current they are producing.

@badideametals Жыл бұрын

I am checking the voltage to see if any of the 3 diodes shorted out due to damage. The current could also be affected, but I don’t mind on these panels as they are used/damaged. I will get a feel for how much current they can push another day.

Spar varnish doesn't work, long term. It cracks and peels off. I used it on 7 panels, cleaned meticulously, coated three layers, big fail. Going to try DAP Ultra Clear sealant. need some xylene to thin it out. Should work better than the Spar Varnish.

You should try before you paint them. Buy one of those spider repair kits for wind shields see if it can fix the spider cracks like it does for car's and than coat them with a sealer.

@badideametals 2 жыл бұрын

The damage was deep in some places. With the amount of dirt and broken glass on the surface of these, small repairs or over the top film would be difficult to verify a successful repair. I learned this trick from a solar installer. They had a specific sealing solution that they mixed themselves… they would not share the ingredient list with me yeas back… so I tried these clear coats spray one and it works for me. At the end of the day, if there is a crack in the tempered glass, seal it how you can. You are just trying to keep water out of the electronics so you don’t see an electrical short on the diodes…

How many years do you expect to get out of the repair?

@badideametals 2 жыл бұрын

If sealed, the glass will last for a long time. The clear coat can yellow or cloud up and that will cause the panel to lower in efficiency. I expect the panel to work for 20 years, but I don’t expect it to keep the voltage for very long.
