I did some calculations a couple of years ago, back up in PA (an unregulated state) the utilities actually BUY solar energy, and the economics are quite a bit different from Florida. I based my calcs, on an outright purchase of the panels (no rentals, lease or other arrangements), I looked at the lost investment opportunity, interest rates, possible changes in taxes, estimated lower electric bill, estimated maintenance costs, expected loss of efficiency, etc.
Bottom line, I did not see a breakeven in my expected lifetime, 20+ years. NOTE: I do not consider the removal cost and re-installation when the roof needs to be replaced about halfway through this period. Please do a careful review of your personal finances and under NO circumstance enter into a LEASE arrangement, there appears to be way too many hidden costs, one of the Orlando TV stations did a report a few months ago on this.
