Generally you can find the degradation curve in their datasheet, and yes, 80% after 25 years sounds possible. IIRC they fade faster with time, so it might be 50

- jeffbee 4y agoI don't see anything in the NREL data that suggests panel degradation accelerates. Most of the panels in their data have higher initial degradation, then less in subsequent years. This LG panel seems to be getting stronger as it ages: https://www.nrel.gov/docs/fy22osti/81172.pdf#page=28 https://www.nrel.gov/docs/fy22osti/81172.pdf#page=28
