Solar in Oklahoma: payback, sun by city and utility-scale capacity

13.12 ¢per kWh paid by Oklahoma homes in 2025, rank 43 of 51 (1 = highest price): the price that solar output replaces

Oklahoma pays back in 15.3 years at $3.00 a watt (rank 36 of 51), 1.8 years longer than the middle state. 1,495 kWh per kW (rank 11) at 13.12 ¢ (rank 43 from the top): sunshine drives it. Across 5 Oklahoma cities, yearly output runs from 1,470 kWh per kW in Tulsa to 1,576 in Lawton. Jul is the best month at 158 kWh per kW and Dec the worst at 89. Utility-scale solar in Oklahoma: 524 MW in 16 plants, 0.8% of 2025 generation; 2,383 MW more under construction or planned.

Oklahoma: December to February give 19% of a year (rank 40 of 51, 1 = most winter); the best month is 1.8 times the worst. Output per unit of sun is highest in Jan (0.83) and lowest in Jul (0.72); PVWatts lowers cell output when the panel is hot, and the sun angle changes with the season. Our runs use one fixed 14% loss figure for every place, so snow or soiling in Oklahoma is not modelled separately.
