How much solar energy does Namibia generate a year?

With approx. 300 sunny days and over 3,000 sun hours per year, the annual solar irradiation reaches values of 2,200 to 2,400 kWh/m2. Due to the constantly high irradiation, PV systems in Namibia generate twice as much electricity as comparable systems in Germany on an annual average.

How much electricity does Namibia generate per kWp?

Due to the constantly high irradiation, PV systems in Namibia generate twice as much electricity as comparable systems in Germany on an annual average. A daily yield of up to >5.6 kWh can be expected per kWp of installed PV capacity. In comparison, natural conditions for wind power are limited in the region.

Does Namibia need electricity?

Namibia is heavily dependent on imports for its energy supply. All fossil fuels (coal, fuels) must be imported. Despite the small population and the low electrification rate of 56%, only about 40% of the country’s electricity needs can be met from its own generation capacities.

Why is photovoltaics so popular in Africa?

The clear focus on photovoltaics is based on the high solar irradia-tion values, which clearly stand out even by African standards and rank among the highest in the world. With approx. 300 sunny days and over 3,000 sun hours per year, the annual solar irradiation reaches values of 2,200 to 2,400 kWh/m2.

Can bioenergy be used in Namibia?

Bioenergy from specially cultivated energy crops is out of the question in Namibia due to land competition with food production and water scarcity. The natural potential for hydropower is estimated at 2,250 MW. Of these, 347 MW are already being used from Ruacana hydro-electric power station.

How much does electricity cost in Namibia?

The 2021/22 base electricity price for large consumers (regional electricity suppliers, municipal utilities) and direct NamPower customers is 1.70 Namibia Dollar (NAD)/kWh (approx. 0.10 Euro/kWh).
