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 Mississippi, 2016–2024
Total solar nameplate capacity in Mississippi reported to the EIA, utility-scale and reported distributed systems. The number of reporting facilities grew 22x (1 to 22) between 2016 and 2024, and the average site size grew from 3 MW to 55 MW per site, a shift toward larger utility-scale installations.
