Goodbye to the idea that solar panels “die” after 25 years. A new study says the warranty does not mark the end, and real-world performance can last for decades (www.ecoticias.com)

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

Do most people go for the full grid independence tho? I think supplemental panels make just as much sense, and utilities forbid disconnecting anyway, so it’s more like if it works it works type dealio

According to Google you need about 300-500 sq ft of panels to power a single family home so it might be simple to start with a 100 sq ft array and gradually build it out to compensate for losses over time and spread the cost. But I'm not a rooftop solar installer shrug-outta-hecks

My impression is that these have to be permitted before they're allowed to be operational (at least in the U$, depending on location or whatever). I'd guess you'd at least have to get a new inspection when more were added on?

Most solar installers around me seem to be concentrating on grifting financing/leases, so I'd think they would make this hard to do.

It does genuinely seem like a good idea, though!
