Idk, my country just inaugurated a gigantic one of these.

Also, fotovoltaic pannels decay with time and have to be replaced, 15 years I think? Their manufacturing isn't also the greenest thing on earth.

You build one of these, and you can run it for a long long time.

15 years I think

This number gets lower every time I see it.

First, manufacturers typically guarantee their panels for 25 to 30 years.

Second, while we can extrapolate from existing data and perform accelerated aging tests, we're actually not completely sure how long PV panels last in the real world because the oldest ones from 1987 are still going.

The usual warranty period is 20 years generating 80% of the nameplate generating Watts

They keep generating reasonable amounts of power 50 or 100 years later, though they tend to get overtaken by new technology in 10 to 20 years, and since they pay for themselves in about 4 years in my area they get replaced while still working well

I think we export our obsolete panels to developing nations
