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. Modeled figures use a typical 6 kW system; your roof, shading, and utility tariff decide the real return. See our disclaimer.

Similar composite solar score

Nearest nationwide matches on the NREL/EIA/DSIRE blend (34/100 here).

Similar modeled payback

Nearest payback-year peers nationwide (9.8 yr modeled 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.
