    Minimum warranty for good solar panels at 90% is 30 years , they will last 60 (no one knows exactly) albeit not as efficient.

      I 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.

        Quite 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…
