Oklahoma Solar Incentives & Rebates Guide 2026

The federal Investment Tax Credit (ITC) allows Oklahoma homeowners to deduct 30% of the total cost of a solar energy system from their federal income taxes. For a typical 6kW system costing $16,500 in Oklahoma, that's a direct tax credit of $4,950. This isn't a deduction — it's a dollar-for-dollar reduction of your tax bill.

The 30% ITC is available through 2032 under the Inflation Reduction Act, then steps down to 26% in 2033 and 22% in 2034. There's no maximum cap on the residential credit. If your tax liability is less than the credit amount, you can roll the remaining credit forward to the next tax year. The system must be installed on your primary or secondary residence, and you must own it (leased systems don't qualify for the homeowner credit).

Oklahoma does not currently offer a state-level solar tax credit. However, Oklahoma homeowners still benefit from the substantial 30% federal ITC, worth $4,950 on a typical 6kW system. Even without a state credit, solar is economically attractive in Oklahoma with electricity rates averaging 13.12¢/kWh.

Oklahoma does not currently offer a statewide property tax exemption for solar installations. This means the added home value from solar panels may increase your property tax assessment. Some local jurisdictions may offer their own exemptions — it's worth checking with your county tax assessor. Even without this exemption, the energy savings from solar typically far outweigh any marginal property tax increase.

Oklahoma does not currently exempt solar equipment from state sales tax. This means you'll pay the applicable sales tax on your solar system purchase. However, the 30% federal ITC and other available incentives more than compensate for this cost in most cases.

Net metering policy: Varies by Utility. Net metering replaced with distributed generation tariff at avoided cost in 2014

Net metering policies in Oklahoma vary by utility. Contact your local electric provider to understand the specific buyback rate and any system size limitations that apply to your service territory.

Oklahoma has a voluntary Renewable Portfolio Standard (RPS) target of 15% by 2015 (voluntary, met). While voluntary, this goal signals the state's commitment to growing its renewable energy capacity. A strong RPS is generally good news for solar homeowners, as it creates market demand for renewable energy and helps maintain favorable solar policies.
