Methodology & Solar Data Sources for Springfield
How we calculate Springfield solar potential and savings: Solar production estimates use NREL's PVWatts calculator methodology, applied to Springfield'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 Massachusetts.
- Solar irradiance for Springfield: 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 Springfield 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 Massachusetts (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:
