Tax credit
#01
Federal Residential Clean Energy Credit (Section 25D) - ENDED
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025. Cash and loan purchases made now receive no federal tax credit, and Oklahoma has no state solar tax credit to fall back on.

#02
Federal Commercial ITC (Section 48E) - via Lease / PPA
Section 48E, the commercial Clean Electricity Investment Credit, survives at 30 percent and is available to third-party owners of residential systems under leases and power purchase agreements. The provider claims it and may reflect part of the value in the rate offered. Ask what they claim and what actually reaches you, and confirm with a tax advisor.
Source ↗ Net metering
#03
Net metering required for systems up to 300 kW
The Oklahoma Corporation Commission requires investor-owned utilities, including OG&E and PSO, to offer net metering for solar systems up to 300 kW. Within a billing period, generation offsets consumption at the retail rate, which is the valuable part. The rules do not require utilities to compensate genuine surplus at the full retail rate, which is where the arrangement differs from classic net metering.
Program
#04
Surplus credited at avoided cost, not retail
Excess generation beyond what you consume is credited at avoided cost rather than the retail rate, in the region of 3 to 5 cents per kWh against an Oklahoma residential average around 13.4 cents. PSO uses monthly netting with a twelve month carry-forward for excess credits. OG&E runs an annual true-up, typically in April, at which any remaining excess credits are compensated at its avoided cost rate. Confirm the current avoided cost figure and the true-up date with your own utility.
Program
#05
No Oklahoma state solar tax credit
Oklahoma does not offer a state income tax credit for residential solar. With the federal residential credit expired for property placed in service after December 31, 2025, a cash or loan purchase now receives no tax credit at either level. Ask your county assessor how residential solar is treated for property assessment at your address, since that is administered locally.
Utility
#06
Municipal utilities and cooperatives set their own terms
The Commission requirement applies to investor-owned utilities. Municipal utilities and rural electric cooperatives, which serve a substantial share of Oklahoma, set their own arrangements for customer generation and are not bound by the same rules. Check the utility name on a recent bill before applying any OG&E or PSO figure to your address.
Net metering · Oklahoma
Monthly netting at retail; surplus at avoided cost
The Oklahoma Corporation Commission requires investor-owned utilities, including OG&E and PSO, to offer net metering for solar systems up to 300 kW. The mechanism has two halves and they are worth separating. Within a billing period, your generation offsets your consumption at the retail rate, so midday production offsets evening usage in the same month before anything is treated as surplus. That is the valuable half, and it puts Oklahoma ahead of states like Georgia and Indiana that measure instantaneously. The second half is less favourable. The Commission rules do not require utilities to compensate genuine surplus at the full retail rate, and both major utilities credit excess beyond your usage at avoided cost, in the region of 3 to 5 cents per kWh against an Oklahoma residential average around 13.4 cents. PSO uses monthly netting with a twelve month carry-forward of excess credits, and OG&E runs an annual true-up, typically in April, at which remaining excess is compensated at avoided cost. The design conclusion follows directly and is unusually clean: build to your consumption and no further. A system matched to your annual usage captures the retail-rate offsetting almost entirely, while every kilowatt hour beyond that is worth roughly a third as much. Municipal utilities and rural electric cooperatives serve a substantial share of the state and set their own terms, so confirm which arrangement applies at your address.
Worth checking before you sign:
taking a rebate can change your net-metering terms, and export credit rules
differ by utility. Your matched installer confirms the exact numbers for
your address.
