PS: Didn't mean to just get angry at solar panels, for wind power is another rip off!
These "5 to 50" devices (5 mph plus wind or they don't move--50 plus and they have to be shut down or else) are incredibly expensive to build, install and maintain for the tiny amount of energy they deliver. (Another case of corporate/ political collusion ripping off the taxpayers.) Without billions of taxpayer money (the government hasn't a penny of its own money) they would not exist. Ditto for most solar panel setups.
