In context: how this plant compares

At 3 MW, Mapleton Community Solar is around the median solar plant in United States of America (3 MW). Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 43.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 71% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 87/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
