I have a generator at my house, along with a geo thermal heating g and cooling system. My neighbor out back of me put in a whole house solar and he says he's loving it. I guess the trick to making it work for you is to get an installer that will turn down the rate that the system charges back to the grid until the inspection, and then crank it up so you they owe you. I'm pretty sure is what he told me, that IO didn't understand fully I think.
