(Just so you know, I have a PV array on my roof. I’m near the break even point, and prices have dropped in the years since I bought the system)...
Then we both know, It will never work.
Be careful, there are those here on FR that will consider you a witch for even considering using a “green technology” let alone actually installing one on your roof. They will fret about lost opportunity cost of money you have invested and when you tell them you’re at the break even point, they will cover their ears and scream “oil is the only answer”.
LOL I bet that includes government subsidies :( Well be sure and tell us when you have tripled or quadrupled your investment.
I almost decided to to invest in solar in the early 90's, but I decided to buy a few BRK.A shares instead. When your solar panels do one tenth as well as my Berkshire shares, I will start being interested.
I was actually considering a solar heat system, but again I am better off paying my heating bills with the dividends from the investment. Anything less than a 4-5 year ROI is throwing away money.
