Solar make excellent sense in certain locations... I have a friend at altitude in NM that is slamming it with solar... My best recollection is that he made a $30k-$35k capital investment with a calculated payoff in 16 years. He thinks it will be paid off in 8 or 9 years instead... then free until the panels/storage units crap out in 25-35 years.
I was hopeful for my WV needs... but probably not going to work out after doing more math. My particulars are about 50% as efficient as his were.
Like buying Time Shares... there are lots of UNEDUCATED SUCKERS out there that refuse to do the hard study... the hard math.
Green Energy is not... NOR EVER BE a one size fits all...
Any .GOV that says it is... LIES.
When we looked seriously into solar power the life of the panels was about 15 years. If the panels will last 25 years it might be cost effective. We have two solar pumps in wells on the ranch. They work very well but we store the water not the electricity.
