Horus 1 y 2 — Guatemala
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 37k homes. It ranks #16 of 77 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).

In context: how this plant compares
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 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
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 1.2% 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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
