How Many Solar Panels for a Heat Pump?
A heat pump can reduce fossil-fuel heating, but it adds electric load. Solar sizing should use seasonal kWh, climate, insulation, and whether the heat pump runs mostly in winter, summer, or both.
Global planning note: cold climates may need more winter energy, while warm climates may overlap heat pump cooling with strong solar production.
Inputs to Check
- Heat pump annual or seasonal kWh.
- Local heating and cooling season length.
- Home insulation and thermostat settings.
- Battery or grid backup expectations.
Best Next Step
Add heat pump kWh to your household usage, then run Panel Count and Savings.
Next step: include heating and cooling load in one solar estimate.
