I suppose it might seem weird to add solar PV to a house with a good solar thermal system. Presumably the net metered PV would supply a good ASHP system but unfortunately I got educated late about these things and I had already installed a propane system connected to a built in propane fireplace. So the electrical will be used for general stuff plus AC, not heating. These things happen, that's why I've learned not to be harsh with other people after the fact. As they say, it could happen to you. Luckily weather around here should supply I'm guessing at least 75% of my heating requirements. Besides, who doesn't like the warm glow of a fireplace.
