minus-square@[email protected]linkfedilinkEnglish1•1 year agoMinimum warranty for good solar panels at 90% is 30 years , they will last 60 (no one knows exactly) albeit not as efficient.
minus-squarelewis6991linkfedilinkEnglish0•edit-21 year agoI just had some installed. Guaranteed 80% efficiency for 20 years. I heavily doubt they will last 60 years. Had energy storage installed as well. Only guaranteed 90% (~4500 cycles) for 10 years. EDIT: double checked the data sheet. They are actually 86% for 25 years with a rated 0.5% per year degradation rate.
minus-square@[email protected]linkfedilinkEnglish2•edit-21 year agoQuite sure mine had 30 years at 90 % . But it was the really good mono ones. Storage is a completely different story. But hey even if they are down to 25% I would keep them and just add new ones. 0.5 would mean 30 for 60 years also…
