Methodology & Solar Data Sources for Clackamas
How we calculate Clackamas solar potential and savings: Solar production estimates use NREL's PVWatts calculator methodology, applied to Clackamas'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 Oregon.
- Solar irradiance for Clackamas: 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 Clackamas household electricity usage.
- Federal tax credit: 30% Investment Tax Credit (ITC) per Inflation Reduction Act, available through 2032 for residential systems.
- Net metering assumes 1:1 retail-rate compensation typical in Oregon (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
- DOE Federal Solar Tax Credit Guide — Inflation Reduction Act incentive details
- DSIRE — State Solar Incentives — searchable database for Oregon
- EIA Electric Power Monthly — Oregon utility rate data
