Methodology & Solar Data Sources for Oyster Bay
How we calculate Oyster Bay solar potential and savings: Annual production = system kW × estimated peak sun hours × 365 × 0.80 system derate × a roof-orientation factor. This is a simplified planning formula, not a PVWatts run for your address. Cost uses a planning price per watt for New York, and bill savings use a planning electricity rate of 19.0¢/kWh (the EIA New York residential average for 2026-06 is 29.49¢/kWh).
- Peak sun hours for Oyster Bay (3.8/day) are a planning estimate in the typical range for New York, not a site-specific NREL NSRDB value. Enter your address in NREL PVWatts for a location-specific production estimate.
- System sizing defaults to a 6kW residential rooftop system with roughly 400W panels; adjust the size and monthly bill to match your home.
- 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.
- Exports are discounted rather than credited 1:1 at retail, because many utilities have shifted to net billing or avoided-cost export rates. Verify your utility's current tariff.
- 25-year savings assume a 2.5% annual electricity-rate increase and do not subtract panel degradation, inverter replacement, or maintenance.
