Oklahoma solar notes
Oklahoma allows net metering but utilities are not required to pay for excess exports and can levy demand charges, keeping solar adoption modest despite good sun.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Oklahoma may offer its own incentives — check locally.
