I put enough solar on our property {6.81 kW ground mounted} so we converted from a 77% efficient natural gas furnace to a 19 SEER/ 10.2 HSPF central unit. We still make more than we use, but as soon as the Prius is paid for and a longer range, sorta' affordable EV is available, I'll be driving on sunshine. At least, that's the general plan.
I hope it continues to work amazingly well for you and that it encourages some of your neighbors to go electric.
