If a 9000 Btu Heat pump consumed 750 watts I would need enough PV panels to make a 1000 watts on a cloudy day.
And enough battery storage for say 6 hours of use ?
I think a 1 level seriously insulated 1200sq.ft custom house could be heated with a 9000 Btu heat pump, as 9000 Btu's is equal to 2,500 to 3,000 watts of baseboard heat. My current 70's house has 3,500 watts in upstairs baseboards that never run full tilt to heat this 1900 sq.ft (1000sq.ft upstairs) home in the coldest part of winter.
A closed loop copper coiled refrigeration filled system might be the best for this ? I will assume the air will get to cold to use a ASHP so ground/water source it should be, for this climate..
The house would have propane cooking and instant hot water.
