Methodology & Solar Data Sources for Tremont

How we calculate Tremont solar potential and savings: Solar production estimates use NREL's PVWatts calculator methodology, applied to Tremont'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 Illinois.

  1. Solar irradiance for Tremont: based on NREL National Solar Radiation Database (NSRDB) — 30-year average peak sun hours per day.
  2. System sizing assumes residential rooftop installation with standard 350-400W panels, calibrated to typical Tremont household electricity usage.
  3. Federal tax credit: 30% Investment Tax Credit (ITC) per Inflation Reduction Act, available through 2032 for residential systems.
  4. Net metering assumes 1:1 retail-rate compensation typical in Illinois (verify with local utility — some have shifted to net billing or avoided-cost rates).
  5. System lifetime standard 25 years with annual degradation of 0.5%/year per industry warranty norms.
