not to dispute the concept of an easy solar install, in theory, but i note add that, in Los Angeles at least, it's hard to imagine a quick, low-cost, DIY solution.

to the LA Department of Water and Power, home solar is basically competition. and the DWP is an important cash cow for city workers and the city budget. they will find ways to add customer fees and reduce the customer's energy bill savings. (e.g. limiting the amount of electricity a home is allowed to feed back into the grid.)

the agency and the city simply need that cash.
