Tulsa Solar Incentives & Programs
Federal Residential Clean Energy Credit (Section 25D)
For 2026 planning, JouleIO does not subtract a federal residential clean energy credit. The IRS says the Residential Clean Energy Credit was 30% for eligible property installed from 2022 through December 31, 2025, and is not available for property placed in service after December 31, 2025.

Oklahoma State Incentives
Oklahoma net metering; no state tax credit
Net Metering: Public Service Company of Oklahoma (PSO)
JouleIO's planning data marks net metering or a solar export credit as available for Public Service Company of Oklahoma (PSO) customers in Tulsa. Export credits can be at retail or below-retail rates depending on the current tariff, so confirm terms with the utility that serves your address.

Solar Energy in Tulsa, Oklahoma
Tulsa, Oklahoma receives an average of 5.2 peak sun hours per day, providing excellent conditions for residential solar installations. With a planning electricity rate of 11.8¢ per kWh (EIA Oklahoma residential average for 2026-08: 14.82¢; U.S. average 18.16¢), below the national average, so payback is slower even with this calculator's 2.5% annual rate-increase assumption.
A typical 6kW solar system in Tulsa produces approximately 9,110 kWh per year, saving homeowners an estimated $1,079 annually. The system pays for itself in about 15.1 years, after which you enjoy essentially free electricity for the remaining 10+ years of the system's warranty life.
JouleIO's dataset carries a modeled solar-adoption value of 5.8% for Tulsa. It is a rough planning placeholder, not a measured count of local installations, so use utility interconnection data or installer quotes if local adoption matters to your decision.

Methodology & Solar Data Sources for Tulsa
How we calculate Tulsa 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 Oklahoma, and bill savings use a planning electricity rate of 11.8¢/kWh (the EIA Oklahoma residential average for 2026-08 is 14.82¢/kWh).
- Peak sun hours for Tulsa (5.2/day) are a planning estimate in the typical range for Oklahoma, 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.

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.
