but they used to be dysmal, like 30% reduction in generation capacity over 5 years.
??? Monocrystalline silicon losses less than .4% a year. That means after 50 years it’s still producing 82% of when it was new. It takes 90 years to get a 30% reduction rate.
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.

Do you know the type of pv panel that was used 20+ years ago? I lived in an off grid house and my dad mentioned that at one point.
Yeah but your point is that solar panels degrade 30% after 5 years, and then you reframe the context for 20 years ago?
Go astrosurf somewhere else.
Any grid has a maintenance cost and degradation. Solar panels isn’t any different.
The fuck are you talking about. I was wrong. Get over it.

Ok, I’m just flat wrong! Til!
