Solar power plant in Santa Rosa, Guatemala. Approximate location 14.04, -90.36.
SolarSanta RosaGuatemala
Horus 1 y 2 is a 80 MW solar power plant in Santa Rosa, Guatemala. Based on reported annual generation of 130 GWh, it can supply roughly 37,228 homes. It ranks #16 of 76 Guatemala power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 1.8% of Guatemala's electricity; the national grid averages 301 gCO₂/kWh (68.3% low-carbon) (2024).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 14.0°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 100% 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: 13/100 — 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 1.2% at warm-season highs here (estimate).
