??? 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.

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.
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.

Ok, I'm just flat wrong! Til!
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.
