Solar Panel Cost in Oklahoma

Fact-checked by Sorted & Saved data desk
Updated Data verified Nov 5, 2026

A typical Oklahoma home uses 1,079 kWh a month[1] of electricity. Covering that with solar takes a system of about 8.4 kW est.[1,2], which costs roughly $25,500 to $35,000 est.[1,2,3] before incentives at the state's median installed price. With Oklahoma's average residential price of 13.81¢ per kWh[4], our model puts payback at about 21 years est.[1,2,3,4,5]. Your quote, roof and utility plan will move these numbers, so treat them as a starting point.

Estimates use the inputs above and the assumptions in our methodology: Oklahoma credits exports below the retail rate; until we add your utility's rate we assume 5.52¢ per kWh, 40% of the state's average price (assumption). Prices rise 2.5% a year; panels lose 0.5% a year.

Solar cost in Oklahoma by system size

Same assumptions as the typical home above; only the system size changes. Prices are the state median before incentives and include the incentives our calculator applies by default in Oklahoma.

Incentives that lower the price in Oklahoma

Federal · tax creditEnding soon

Business credit for leased and PPA systems (48E)

Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027[6]

If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.

Who
Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.

How Oklahoma utilities credit your solar

Under 17 O.S. 156 and OAC 165:40-9, utilities regulated by the Oklahoma Corporation Commission offer net metering to distributed generation of 300 kW or less. Excess production is purchased at the utility's avoided energy cost and paid or credited in the next billing cycle.[5]

We have not added every Oklahoma utility yet, so the estimates on this page use the state-level rule: Oklahoma credits exports below the retail rate; until we add your utility's rate we assume 5.52¢ per kWh, 40% of the state's average price (assumption).

FAQ

Frequently asked questions

How much do solar panels cost in Oklahoma?

At the state median installed price of $3.60 per watt est.[3], a 8.4 kW est.[1,2] system that covers a typical home's use costs about $30,200 est.[1,2,3] before incentives. Quotes vary with roof, equipment and installer.

How long does solar take to pay for itself in Oklahoma?

For a cash purchase at the state's average electricity price of 13.81¢ per kWh[4], our model estimates about 21 years est.[1,2,3,4,5]. Your utility's export credit and rate plan matter a lot; see the export-credit table above.

Is there still a federal solar tax credit?

Not for homeowners who buy. The Federal Residential Clean Energy Credit (25D)[7] does not apply to systems whose installation is completed after December 31, 2025. Leased and PPA systems are different: the company that owns the system may still claim a business credit.
