How Long Do Solar Panels Last?

It's a fair question. What kind of life can you expect from a set of solar panels? How many years of free electricity can you get?

Well if the 25-year warranty isn't enough to easy your worries, check out this energy-nerd (and i mean that in the nicest way) from America. Having got himself some solar panels way back in 1980, he took one down last year to do some tests on it.


Turn out that even after 30 years on his roof, the panel is still performing to 100% of factory specifications. Pretty impressive for something made in 1980.
