The good news and bad news for heating with a solar-powered heat pump.

Using solar in the winter for heating may have its challenges...
Shorter days? Check.
Weaker sunlight because more of the sun's rays need to go through more atmosphere? Check
Potentially your solar panels are at an angle of trajectory more suited for summer--something like your latitude minus 14 degrees? Check
Snow on your panels? Check
Need for more BTUs, since for much of the country, going from, say, 35 degrees for heating to a setpoint of, say, 75 degrees is more of a lift than going down from 95 degrees in air conditioning to 75 degrees? Check
But, solar panels are around 1/3% per degree below 77 degrees Fahrenheit more efficient in the winter, where their 1/3% per degree above 77 degrees less efficient in the summer. And, solar heating is free, so you can keep your house (or your cabin) heated all winter long, and if you come back (at least during the day), the house will be comfortable. #solarheat #diysolar #heatpumps #shorts
