Roof sun exposure
How the math works
This calculator uses publicly available average cost-per-watt data by state from the National Renewable Energy Laboratory (NREL) and regional peak sunlight hours from NOAA solar irradiance data.
Your actual savings depend on roof orientation, local installer pricing, electricity rate escalation, equipment choices, and financing terms. Always get multiple quotes from qualified installers before making a decision.
