Has Solar Demand Finally Hit Bottom?

rdasher needs to do his homework on payback for solar. I do solar sales and installation for a living in Florida with a sophisticated spreadsheet tool for comprehensive financial analysis. Payback period for both residential and commercial solar is running from 8-10 years now and internal rate of return (IRR) from 10% to 22% based on PV system size, local rebates, incentives, and Federal tax credit due to economies of scale. Try making that kind of return on your money with any other investment in current credit market.
