How We Calculated This

Our solar ROI calculations use data from the National Renewable Energy Laboratory (NREL) PVWatts API, which models solar energy production based on location-specific solar irradiance, weather patterns, and panel tilt angles. We assume a standard 6kW residential system with south-facing panels at optimal tilt.

Electricity rates are sourced from the U.S. Energy Information Administration (EIA). Annual savings are calculated by multiplying estimated production by the local electricity rate. The ROI score represents total 25-year savings divided by system cost.

These estimates do not include the federal 30% ITC tax credit, state incentives, SRECs, or utility rebates, which can significantly reduce the effective payback period.
