I’m in Canada , in a tight valley where it snows a ton. I pay 13 cents a kWh for electricity. I installed 7.8kw of rooftop solar for $8k out of pocket, all of which is on a ten year interest free loan. In 12 months it makes smack on $1000 worth of electricity. So my payback is 8 years ( less, actually. The price of electricity here is already pre approved to increase no less than 5% a year) After that I get $1000 of power per year for twenty or so years. The term no brainer doesn’t seem enough.
