Answering myself from GPT:
Typical lifespan of solar panels:
- 25 to 30 years is standard.
- Most panels still produce 80–90% of their original capacity after 25 years.
📉 Degradation rate:- On average, solar panels lose about 0.5% to 0.8% efficiency per year.
- After 25 years, a panel rated at 100W might still produce about 85W–88W.

YearsRemaining Efficiency10~92–95%20~85–90%25~80–88%I have tested them using sawhorses in the summer time I laid in their side and in the winter I had the sawhorses standing up. A nail or screw through two of the grommets hold them in place.
I have a few rigid 200 watt panels in the garage for the same use, but they are a lot heavier and awkward to move around. They are two heavy for the sawhorses to hold in position.
