Here's my payback calculations based upon the ave. monthly (3 yr ave) energy my system (3.45kW) produces. The 1st couple of years besides savings from Nat Grid on my electric, I could sell REC credits, originally they were $0.06 KWH but 2 years ago the price dropped to $0.03 KWH and I didn't renew the contract however for this example I have left them in.
When I first did the calc. the fully burdened costs was $0.12348 KWH (red), check this month's bill it is already up to $0.1784 over the last 5 years, what will it be 20 yrs from now? Table show another 3X increase. This is a very simple analysis just assuming you pay the same KWH rate the entire time vs. amortized in any way.

 Given the diversity of the human species, there is no “normal” human genome sequence. We are all mutants.
