Solar in Wyoming: mid payback · strong sun
Wyoming sits in the middle of the payback pack at 15.3 yr (#30), so irradiance (5.5 kWh/m²/day) and the 1 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.

Score and payback neighbors for Wyoming
Two non-geographic peer sets for Wyoming: composite score neighbors and payback-year neighbors (deduped so each row links a distinct comparison).
Similar composite solar score
Nearest nationwide matches on the NREL/EIA/DSIRE blend (28/100 here).
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.
Solar resource from NREL; electricity rates and installed capacity from the U.S. EIA; incentive programs from DSIRE. See our methodology.
