Now when you talk about solar on the roof, learn about the financial friend Internal Rate of Return, aka Discounted Cash Flow Rate of Return. This tool allows you to compare a solar array to other uses of your money. Along with Monte Carlo analysis, you can decide: Solar on the roof, or 10 year Treasuries? Right now I am better off buying power, and investing money. Your mileage may vary. It is just an investment like any other.
Solar City installed my solar and I have recovered the cost in five years. I see that as a 20% return on my money.
