Methodology & Solar Data Sources for Rochester
How we calculate Rochester solar potential and savings: Solar production estimates use NREL's PVWatts calculator methodology, applied to Rochester's specific solar irradiance (peak sun hours), tilt angle, and azimuth. Cost figures combine NREL's Annual Technology Baseline for system pricing, ENERGY STAR's database for residential PV averages, and EIA Form 861 utility rate data for New York.
- Solar irradiance for Rochester: based on NREL National Solar Radiation Database (NSRDB) — 30-year average peak sun hours per day.
- System sizing assumes residential rooftop installation with standard 350-400W panels, calibrated to typical Rochester household electricity usage.
- Federal tax credit: modeled as 0% for 2026 residential installations because IRS guidance says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025.
- Net metering assumes 1:1 retail-rate compensation typical in New York (verify with local utility — some have shifted to net billing or avoided-cost rates).
- System lifetime standard 25 years with annual degradation of 0.5%/year per industry warranty norms.
Authoritative US solar data sources:
- NREL PVWatts Calculator — official US solar production estimator
- NREL National Solar Radiation Database — 30-year solar irradiance data
- IRS Residential Clean Energy Credit — 2026 federal residential credit status

Solar Disclaimer: Solar savings vary based on roof orientation, shading, system quality, installer markup, financing terms, utility rate plan, and policy changes. Always get 3+ quotes from NABCEP-certified installers and review contracts carefully. Tax credit eligibility depends on tax liability — consult a tax professional.
