Hey look, a post attempting to make the discussion about me after ignoring my previous response by also trying to make the discussion about me. Almost as if there's a pattern here. I wonder why there's a need to try and avoid discussing the facts I brought up. How curious.
This is an article chosen at random. It is, however, the page of a company that promotes solar panels and profits from their sale.
From this article, panels will have lost less than 4% of their output after the 5 years in the post I was quoting. People are really making a big deal over that?
Well, you managed to find a single fact, from a dozen or more to be found in that article which aren't so comforting, that says what you hoped to find. And the panels you are referring to here are those of one type only.
When we take in the whole picture, it's far from reassuring.
The manufacturer of the solar array that we have on our campus has a warranty of 90% for 10 years and 80% after 25 years. If you don't account for this in your life cycle costs up front your calculated payback will be skewed sooner than it really will be.
