When you can build a new home with solar panels all over it and tesla battery> arrays in the basement to keep you going at night, it's just possible to get to> the point where you receive a check from the utility company every month, rather than a bill .... I think, and hope, this is the future of power in homes. John Why should a house-installed solar installation use batteries at all? Batteries are big, heavy, inefficient, have a limited lifetime, and are made of expensive and potentially toxic materials, which can sometimes explode with little or no warning. I think of the AC power-grid as an infinite-capacity, indefinite lifetime, virtually 100% efficient, "battery". Jim Bell
