About SunPowerPeek

SunPowerPeek is a free resource that helps homeowners understand solar panel costs, savings, and government incentives across the United States. We provide detailed solar data for all 50 states and 500+ ZIP codes, plus tools to help you calculate your solar ROI.

Our Mission

We believe transparent solar data empowers better decisions. Whether you are evaluating whether solar makes sense for your home, comparing costs across states, or trying to understand available tax credits and rebates, SunPowerPeek provides the data you need to make an informed choice.

Data Sources

Our solar data comes from the National Renewable Energy Laboratory (NREL) for solar irradiance and production estimates, the Database of State Incentives for Renewables & Efficiency (DSIRE) for incentive programs, and the U.S. Energy Information Administration (EIA) for electricity rates. System costs reflect current residential solar market pricing. We update our data regularly to ensure accuracy.
