Very true. At my house in CT where electricity rates are crazy, I had 28 panels installed and put online in December 2010. Two months later, I stopped buying electricity from the grid and haven't bought a single watt since. My metering bill is around $12 per month. I also have an inverter with battery backup; 4 of the panels just keep the batteries charged. 4 deep cycle sealed marine batteries that take up a 3'x3'x3' space on the floor of my basement. Not as cool as a LiOn Tesla Powerwall, but one heck of a lot cheaper and easy to replace. In a power outage, the inverter switches on instantly - your computer screen will not even blink when this happens. I don't think solar makes as much economic sense in Florida as it does in other states with expensive kwh costs.
