Solar panels are usually sold with 25 to 30 years of performance promises. But what happens after that, when the warranty language is long gone and you are
We have some 25yo panels around, small 25-40W ones. They usually die because the diode goes (which is fixable) or one of the traces in the back gets water in it and it shorts. We’re probably down to about 2 out of 10, and those were high quality panels at the time.
And for what we paid for one 40W panel then, you could buy 2000W worth today.

The development in recent years has been insane. I’m positively astounded.
