I note with some interest though that most roof top systems put only enough out that they could, in theory run a Tesla Super Charger to a Tesla battery supply. You could then pick a point in the afternoon where you did the ‘switch’ and switched over to inverters running off the Tesla battery pack. Providing electrical load from that point until it got below a set charge point on the batteries. Some days you’d probably go from 4PM to 9 or 10PM, others only until 6 or 7. But you would get the benefit of not having to pay for that power when you were running off the Tesla. Elon if you’re reading this you should figure out how to make that happen, you’d get better volumes on the batteries with Tesla (better economics of scale) and people could do this without utility participation.
