RE :’So his $20K was paid back in a year of free electric before any interest was due.
Really? He had $1666 electric bills?”
......
I call BS. The typical solar installation “breaks even” in about 45 years compared to fossil fuel power, long past the service life of the components. That is why it fails without tax funding to cover the costs.

Oh-Oh. math, not prepared for that.
His peak electric bills summer were in the neighborhood of $600 per month so maybe $4-5K a year which it now costs him nothing. Now I have to go back and ask him where he got the “I already made it back” line from.

Also if he generates enough to make a profit (net positive) beyond what he uses at night. I think he said even on cloudy days they generate electric.

A new AC could lower those bills too.

I guess he left something out of this rosy tale.

Where solar replaces existing coal/natgas power the payback on the investment is generally about twice the service life of the system from my experience.

Solar might be cost effective where no power exists.
