Solar power plant in Tacna, Peru. Approximate location -17.9937, -70.3361.
SolarTacnaPeru
Tacna is a 20 MW solar power plant in Tacna, Peru. It is operated by Tacna Solar S.A.C. Based on reported annual generation of 44 GWh, it can supply roughly 12,571 homes. It ranks #31 of 32 Peru power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 3.0% of Peru's electricity; the national grid averages 238 gCO₂/kWh (63.6% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a cold desert climate (Köppen BWk) — Southern Hemisphere, latitude 18.0°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 83% 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: 19/100 — 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).
