    Monocrystalline silicon was used 20 years ago. It’s the oldest solar technology.

    According to the source data in a link in the page I linked thin film CIGS rollable solar sheets was the least durable. Panels installed before 2000 had a degradation of 3.5% a year. That’s 10 years to lose 30%. But CIGS solar systems installed after the year 2000 show only .02% degradation a year. The document talks about manufacturing defects that were corrected.
