Don, I did not calculate the payback, but did so now to answer your question. Based on no change to the approx 12.6 cents/kWh, our usage last year, and no tax or other advantages or payment for more energy produced than used, it would take 65 years. Assuming 30% tax credit, it drops to 45.5 years. There may be other payments that will shorten it more, but not likely to be paid in dollars in my lifetime The payback, in another sense, is immediate. I enjoy watching the electricity meter run backwards, and like the idea of leaving a tiny carbon footprint. Some prefer other payback scenarios, but I like this one a lot.
