I looked for some reference material and I found a "rule of thumb" which claims that PV panels lose about 1% efficiency per year of operation and can last 25-30 years.
Nuclear power stations (in China) are designed for a 40 to 60-year operating life.
- kragen 7y ago25–30 years is the design life; they can last a lot longer than that. Silicon is an astoundingly stable substance.
