If you pair a solar electric panel with an air to air heat pump the efficiency will match a solar thermal panel and you can run it off the grid or battery power once the sun goes down.

Alas, reality intrudes. I would like some hard data please. Latitudes where this will be effective? Square feet that can be heated in winter, and the temperature zones where that will be effective? Cost per BTU/kJ based on some baseline climate parameters?
This is of great interest. I hope you can help me understand how this may apply to my situation.
yeah, but ... what would PIE do? Especially concerning this tiny ad:
