The Solar Quote Check

The GreenLifeDiary workbook for checking a rooftop solar quote: seven checks, a real payback year, and the questions to ask before you sign

The Solar Payback Calculator on this site gives a quick first look: net cost divided by first-year savings. It assumes the panels never fade, that every kilowatt-hour is worth your full retail rate, and that you paid cash. A quote on your kitchen table deserves more. The Solar Quote Check takes the figures printed on a quote and checks each one: the real net cost and price per watt, the production claim against an independent estimate, what your utility pays for exported power, panel fade, the price-rise assumption behind the savings chart, and the total paid on a loan. Then it walks the years to the one where savings really pass what you paid. On the worked 7 kW quote, the simple payback of 13.8 years becomes 14.3 with fade, 12 with a 3% price rise, 25 if most power is exported at $0.05, and never within 25 years on a 20-year 7% loan. Not financial, tax or legal advice, and it recommends no installer, loan or lease. Includes a three-quote comparison, eight questions to ask in writing, a payback grid and a cut-the-load page. With your purchase comes a personalised sheet walking your own quote under different assumptions.
