Solar in Oklahoma: mid payback · strong sun
Oklahoma sits in the middle of the payback pack at 15.5 yr (#32), so irradiance (5.3 kWh/m²/day) and the 2 tracked programs matter more than ranking alone.

Stamps derive from this state's NREL irradiance, EIA Form 860 / Electric Power Monthly nameplate, and DSIRE incentive row (score, rank, sun, rate, payback, capacity, programs, peer), not a quote or site assessment.

Installed solar capacity in Oklahoma, 2015–2024
Total solar nameplate capacity in Oklahoma reported to the EIA, utility-scale and reported distributed systems. The number of reporting facilities grew 14x (1 to 14) between 2015 and 2024, and the average site size grew from 3 MW to 12 MW per site, a shift toward larger utility-scale installations.

Similar composite solar score
Nearest nationwide matches on the NREL/EIA/DSIRE blend (29/100 here).
Similar modeled payback
Nearest payback-year peers nationwide (15.5 yr modeled here).
- Delaware · 15.4 yr payback
- Missouri · 15.6 yr payback
- Mississippi · 15.7 yr payback
Peers are nearest-neighbor matches on published composite scores and modeled 6 kW payback years; rankings above use the same fields but sort the full corpus.
