I'm in the middle of price quotes and a proposal for solar panels. Hopefully, I will have something implemented before or if ever needed.
But you can't eat the solar panels.
Yes they work, an Uncle in San Diego, had one of the first ones, he used it to heat hot water for the showers in about 4 apartments.
Worked, until the relatives showed up, for a week.
He used it for years.
Today's are not even related to his.
