That reminds me, talking about maintenance.
solar panels lose efficiency due to age. so you have to ask how that works. it is at some point necessary to replace them.
The issue is payback costs don't line up with when they have to be replaced.
Yep, lots of little details like that. CA recently passed a law saying all new houses needed to have solar panels but it was quickly pointed out by a bunch of people that the state of CA fudged the numbers when they claimed it would pay for itself. At the moment it doesn't seem close to paying for itself for most installs. It might be possible with a new house in CA that is designed to be super efficient that a solar array could provide power and eventually pay for itself but I can't see it happening in Montana on a house that wasn't designed for it. Most likely zero chance of that happening.
