Hwaseong

Hwaseong is a 1 MW solar power plant in Chungcheongnam-do, South Korea. Based on its capacity (estimated), it can supply roughly 425 homes (estimated). It ranks #202 of 204 South Korea power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 6.1% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 37.1°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 17% 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: 59/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

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