#offgrid hot water from #PV achieved. Heated 66 gallons today with about 8 kwh, with another 8 kwh going into the car, and the usual 3 kwh for the rest of the house's loads I've wanted solar hot water for a long time, resisted the complexity of solar thermal, pondered on direct DC heating but it's got issues, in the end cheap solar panels and hybrid heat pump wins.
