When considering adding a solar system, like the ones mentioned on this website, to your home don't think of it as just another home renovation. Unlike home renovations that increase your enjoyment of your home, you typically will not see any financial reward from the reno until you sell your home. (This assumes that the reno adds more value than cost to your home.)

Adding a solar system is like adding a money tree to your property. Using our OPVPower3600 example, for a total investment of less than $3,000 your "money tree" will provide an annual crop of about $3,200+ to you. This will continue for at least 20 years, and longer.

So for the 20 year contract period, your money tree will provide you with over $50,000 in income. 

I have yet to find a better source of money, for my investment dollar. If you know of one, please let me know.
