Oklahoma Solar Incentive Programs

---

Oklahoma is a great location for solar systems, with 234 sunny days on average per year. possesses a favorable environment for harnessing solar energy. While it may not claim the top spot in terms of sheer sunny days, Oklahoma’s climate offers conducive conditions for viable solar power projects. The state demonstrates a robust commitment to renewable energy through a suite of incentives and programs expressly designed to stimulate solar adoption.  Here are some of the solar incentives available to homeowners and businesses in Oklahoma:

Federal Incentives

Federal Investment Tax Credit (ITC)

Commercial solar energy systems can take advantage of the Federal Investment Tax Credit 48E, which provides a tax credit of 30% of the total cost of the system, provided prevailing wage and apprenticeship requirements are met. 

Residential systems can no longer claim any federal solar tax credit, as the One Big Beautiful Bill eliminated it for systems installed after January 1st, 2026. 

Commercial Depreciation

Commercial asset owners can write off 100% of a project’s value in depreciation in the first year. The One Big Beautiful Bill reinstated the 100% bonus depreciation, while simultaneously eliminating the Modified Accelerated Cost Recovery System (MACRS) that previously depreciated solar energy systems over 5 years. 

The depreciable basis of a project is reduced by half of the ITC value when combined with the 30% ITC. Here’s a quick example:

• Project cost = $800,000
• 30% credit = $240,000
• Reduced depreciation basis: $800,000 – ($240,000 / 2) = $680,000

A company’s tax rate is then taken into account to calculate the exact amount they’re able to write off. 

Net Metering:

Oklahoma requires investor-owned utilities and electric cooperatives to offer net metering to all customers. All systems up to 100kW are eligible, and energy in excess of the total monthly on-site usage is credited to the customer’s account at the avoided cost (around 2 to 3 cents per kWh).

Solar Power Rebates:

Oklahoma does not offer state rebates, but you can get a lump sum payment or your installer will take the amount off the final installed price.
