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) and represent state-level residential averages. Annual savings are calculated by multiplying estimated production by the local electricity rate. The payback period divides system cost by annual savings. The ROI score represents total 25-year savings divided by system cost.

These estimates do not include federal tax credits (currently 30% ITC), state incentives, SRECs, or utility rebates, which can significantly reduce the effective payback period. Actual results vary based on roof orientation, shading, local weather, and utility rate changes.

Solar Outlook for North Carolina

North Carolina receives 5.16 kWh/m²/day — 4% above the national average. Lower electricity rates of $0.125/kWh extend the payback to 12.9 years, though the federal 30% ITC and state incentives can meaningfully improve the economics.
