We went with a small panel house, and a little woodstove.
A little fire in the morning to take off the chill, sun in the south windows all day. Furnace only runs at night when the house drops below 60 degrees, and that only happens when it’s in the ‘teens outside.
Smartest move we ever made.
Some years ago, we lived in a house with solar. What a bunch of junk, and actually made the house colder. We had to replace the wornout workings when we went to sell.
Expensive, inefficent boondoggle. (Try roofing around those panels.)

The payback on the GSHP was less than five years. We have no had a single service call on this unit. Four wells are 200 feet deep under the driveway and pull 59 F liquid into the house and through the heat exchanger. Electricity bumps it to 68 or whatever we set. It also does a great job with AC although the dehumidification could be better.
