Most panels have a 25 year 80% production warranty. Unless they're planning on being out of business, they're not planning on them lasting <25 years. So their useful life is significantly longer than 30 years, unless we come up with massively more efficient panels and the land opportunity cost is high enough that we should swap them out rather than let them just keep pumping out electricity. |
