Frequently Asked Questions

If I already purchased an appliance, can I be reimbursed later?

Since no guidance has been released, the answer is likely no. We do not yet know all the standards the equipment must meet or other requirements. Furthermore, households must be income qualified. The best way to ensure a possibility of reimbursement is to wait until guidance comes out and the Oklahoma Department of Commerce has designed the program according to federal requirements.

When will the rebate funds be available?

Unfortunately, the Oklahoma Department of Commerce does not have answer to this question yet. The U.S. Department of Energy has not yet provided an exact timeline for implementation nor notice when funds will be released. Likely either late 2023 or early 2024. Please revisit this site on a regular basis or sign up for alerts to receive notification when the program is available.

Solar for All

Solar for All, a program of the U.S. EPA, will tackle the financial and non-financial barriers that limit the ability of low-income and disadvantaged communities across the country to benefit from the rapid growth in distributed solar capacity.

The Oklahoma Department of Commerce State Energy Office is pleased to announce a request for information is now available for the new Solar for All competitive funding that Oklahoma will be applying for from the United States Environmental Protection Agency (U.S. EPA). The information gathered from the RFI will be used to inform future solicitation(s) and the grant application. The RFI can be found here on the Commerce website.
