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.
So you don't waste all those KW accumulated during the day. Modern advanced batteries (like the ones sold by tesla) perform quite extraordinarily well. Apparently you completely misunderstood what I said.
I think of the AC power-grid as an infinite-capacity, indefinite lifetime, virtually 100% efficient, "battery".
But it's not a battery. There is lots and lots of carbon being burned down to keep that grid humming. But a given house can treat the AC grid as if it's a "battery". If the solar panels generate more electricity than the house happens to be using, they will throw the power into the AC grid, and in effect run the meter backward. The power-generation systems don't have to work as hard, when they are partly supplied by excess residential electricity.
