SolarWestern CapeSouth Africa
Swartland Solar Power Plant is a 5 MW solar power plant in Western Cape, South Africa. It is operated by SlimSun. Based on its capacity (estimated), it can supply roughly 2,127 homes (estimated). It ranks #117 of 122 South Africa 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 8.0% of South Africa's electricity; the national grid averages 699 gCO₂/kWh (17.8% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Southern Hemisphere, latitude 33.4°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 73% 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: 23/100 — 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).
