SolarSan JuanArgentina

PLANTA PILOTO FOTOVOLTAICA SAN JUAN 1 is a 1 MW solar power plant in San Juan, Argentina. It is operated by EPSE - ENERGIA PROVINCIAL SOCIEDAD DEL ESTADO. Based on its capacity (estimated), it can supply roughly 510 homes (estimated). It ranks #232 of 236 Argentina power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 3.4% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a cold desert climate (Köppen BWk) — Southern Hemisphere, latitude 31.4°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 52% below 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: 28/100 — this site sits in the bottom 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).
