To the Erma spouter who said their solar panels power 2 heat pumps for their home. I doubt it. Do you have heat at night? Then your panels feed into the grid and ACE’s system powers your heat pumps. Not to say you’re not saving $. You may be (maybe not too, my electric bill is less than my neighbor’s and I don’t have panels) but it is unlikely you’re powering anything directly in your home. At night or cloudy days, traditional generation is keeping you warm, your lights on, and your tv and router working.
