Hello to all. I am new here and new to solar power too.
I have a small shed where I would like to make a small solar system, mainly to have lights and maybe some small radio or applience to use from time to time.
Anyway from a cooworker I got 2 panels basicaly for free. This panels are used. I can see in some areas some small brown spots, there are some , I see some microcracks and what appears to me some ''delamination''. I measured the voltage when put on sun (there were some small shadows from branches but almost all on sun) and got around 41,3V from both of them, open ciurcuite voltage is rated at 45,5V.
My question is, are this 2 pannel still usable? And if they are, is there any fire hazzard due to this brown spots.
I attach some pictures.
Thank you for your help in advance.
