Groundbreaking study shows how solar panels age after 30 years of use: ‘It’s an important message to the photovoltaic industry’. Astudy of six, 30-year-old arrays in Switzerland found them to still be working well, retaining more than 80% of their initial power.

It’s be great to see a study with statistically significant data. I believe NREL studies this, but don’t have that info handy right now
the panels would do even better if they cleaned them once in a while
