The Economist has a look at the rapid spread of small scale solar power systems in Africa, driven by cheap solar panels and low-power led lighting - Africa unplugged.
Off-grid solar is spreading at an electrifying pace. An industry that barely existed a few years ago is now thought to be providing power to perhaps 600,000 households in Africa. The pace of growth is accelerating in a continent that, more than any other, is rich in sunshine (see map). Industry executives reckon that over the next year the number of home-power systems on African roofs will grow by 60-100%. M-Kopa, the market leader, has installed 400,000 systems and, at its current rate of growth, may add another 200,000 to that number over the next year. Smaller rivals such as Off Grid Electric, Bboxx and Azuri Technologies may well double their client base over the same period.
