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.

States near Wyoming on score and payback
Two non-geographic peer sets for Wyoming: composite score neighbors and payback-year neighbors (deduped so each row links a distinct comparison).
Closest match: 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.
