This is simply not true. I live in the south west, aka the desert and many people have solar, many more people are adding solar and it is not just extremely wealthy people as there are state and federal grants per mentioned before that can greatly reduce the overall cost and make them affordable for a middle income family. You are seriously just pulling info out of your ass dude.
Guess what, numbnutts: You have no more sunlight at your place in the southwest than I do here in the Southeast. We're both on about the same exact parallel. At best, you might get 20 more minutes of usable light than I do.
Just because it's hot doesn't mean you get more power.
And there are very, very few federal grants anymore. Most have already expired. Not only that, but power companies have also done away with sell to grid incentives. They actually CHARGE you now to give them power or even hook to their grid. That was the entire reason behind Tesla's battery system: it doens't hook to your existing power grid.
Watch less discovery channel and actually research it. As I've said elsewhere, my wife and I did two months of research on it. To knock about 25% off our power bill the system would have run about $35,000 dollars. It would take about 20 years to break even.
Now, that's not really that bad as it also adds value to your home when you sell it DEPENDING ON how old the system is, because the life expectancy is only 25 years, so you'll be replacing all the panels and battery banks at that time to start all over again.
Anybody that's stupid enough to believe that some dude pieced together a system for pennies that knocked 85% off his power bill is a blithering idiot, plain and simple. That has been my point from the outset that you keep ignoring for some stupid fucking reason.
