Why Solar Power In Sub-Saharan Africa Is Spreading So Fast

Why Solar Power In Sub-Saharan Africa Is Spreading So Fast

In 2009, just 1 percent of sub-Saharan Africa’s 910-million people used solar lighting.

Now close to 5 percent, or 11 million people use solar, according to a video by TheEconomist. The International Energy Agency, a Paris-based government think-tank, estimates 500 million more will have solar electricity by 2030.

Why is solar power spreading so fast in Africa?

– Solar panel technology has improved. Mass production and better efficiency mean the price per watt has dropped to about 30 cents for photovoltaic panels.

– Low-energy bulbs are cheaper and better. They charge in the daytime, produce
light at night, and cost as little as $8. They are replacing dangerous and expensive alternatives such as kerosene, candles, fires, or no light at all, which encourages crime and affects productivity, TheEconomist reports.

– Lithium-based batteries store more electricity and hold about 2,000 charges compared to nickel cadmium batteries, which die after 500 recharges.

– Solar power is increasingly well financed in Africa. Aid donors are sponsoring more and bigger projects for things like fridges and TVs. Bigger solar systems can run an irrigation pump, clinic, school, grain mill or an entire village, TheEconomist reports.
