Should I Get Solar Panel Roofing? Why It Doesn’t Make Sense For Most People

[@leehammond3289]

The median Solar panel degradation is 0.5/year so that's 10% in 20 years or 12.5% in 25 years the standard life expectancy.

Well maybe then I have some especially low quality solar panel installers barking up my tree, because they never deny that number! But thanks for pointing that out - I did Google it (not that I don't believe you) and 0.5 to 1.0% seems to be common.
