    The only reason most people seem to worry about the rate of return on investment with solar is the fear that they won't recoup their investment before they sell.

    In CA, at least, that fear has been dispelled in a recent study that showed people got back the money they'd spent on the system at the time of sale. What this means from a practical standpoint, is that if you plan to sell your home, the energy you get is essentially free, and the system cost is borne entirely by the purchaser. Not a bad deal!

    If, on the other hand, you don't plan to sell, and for whatever reason your system ends up with something ridiculous, like a 20 yr payback (which is awfully long given current technology and many state and federal rebates/tax credits), then your worst case scenario is a 5% annual return on investment. That's better than just about anything else you can invest in (efficiency & conservation and solar hot water being the primary exceptions). And, unlike other investments, it's inflation-proof.
