SolarCentralGhana

Gomoa Onyadze is a 20 MW solar power plant in Central, Ghana. Based on its capacity (estimated), it can supply roughly 8,509 homes (estimated). It ranks #6 of 6 Ghana power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 0.7% of Ghana's electricity; the national grid averages 469 gCO₂/kWh (36.2% low-carbon) (2024).

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 5.3°N — which shapes how much energy it can produce and how its output varies through the year.

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).
