Buy MY solar system on MY house paid for with MY money and tailored to MY needs is very efficient. Like everything else in life, it's always more efficient if the one that's paying for it and benefiting from it is also the one making the decisions.
That's why decentralized green energy works if you're in a good situation for it (mine produces 50% of all the electricity needed for my 2-story all-electric house and will pay for itself on about the 10th year). That's also why "green" energy like the Dims want it doesn't work: it's always inefficient because it's forced onto people who don't want it and paid for by people who don't want it, but decided on by bureaucrats.
I see such your use as appropriate, however even that is massively subsidized. To date all such solar investments get massive tax payer subsidies. I could be wrong but I would guess your 10 year return would have gone past and useful time, for return of investment, if the government subsidies were not available.
Know several people who went your route and ALL of them stated unequivocally, “if not for the government subsidy it would have been unfeasible.” These are people in the Nuclear Power field just like myself.
Using tax dollars to prop up a failing business model is just another thing killing this country.
Ery logical. Question for you because I’ve never seen a real answer. What is the expected life span of a solar panel and does its energy output degrade over time? So you are getting 50% return now. Will it be that way by the time it pays for itself in 10 years? And what the maintenance required for it (i.e. windex the panels twice a year? Replace batteries?)
Thanks
