SunSource® Home Energy System Savings Calculator

Discover the difference solar power can make.

The SunSource Home Energy System converts the sun's energy into electricity that can help reduce the cost of your utility bills. This calculator will estimate how much you can save each year on the heating and cooling portion of your bill, which typically accounts for 56% of your total home energy costs*. It will also calculate the potential environmental benefit.

**   Percent savings for Canada based on 2750 heating load hours (same as U.S. region 5). Northern regions of Canada may have even higher heating load hours.

*** Estimated annual operating cost savings of a 3-ton XC21/XC17 air conditioner or XP21/XP17 heat pump with solar modules, compared to a 10 SEER air conditioner or 10 SEER/7.0 HSPF heat pump. Equipment cost-savings estimates are based on the U.S. Department of Energy (DOE) annual performance factor (APF) method for heat pumps (10CFR part 430). Estimates of annual solar energy production are calculated for a centrally located city in each DOE heating region, using National Renewable Energy Laboratory’s (NREL) PVWatts, Version 1.
