Several of us use geothermal heat pumps combined with solar PV. Pinball uses mini splits - which are almost as efficient as a geo heat pump - but without the cost of drilling the wells.

I use an open loop geothermal heat pump meaning it uses well water which is then dumped into a pond (so called "pump and dump" system). The ponds are then used for livestock watering and irrigation.

Your location calls out for minisplits . . . . .

ps watch the Renvu page carefully and buy panels + inverters when they are on sale - which is often. My last purchase was Hanwa Q cell 265 W panels @ $0.51/watt, Enphase M215 at $85 each and the Enphase Engage trunk cable at $10 per drop. I negotiated for the trunk cable drop price . . . but it was a simple ask and they said OK!
