Families in remote and impoverished areas suffer from a lack of basic infrastructure. Kerosene lamps are used to light the home after dark but this method is expensive (studies put the figure at between 10% and 25% of household income) and potential dangerous to users and the environment.
Solar-powered lamps offer a cheaper and safer means of light that replace kerosene-fuelled lanterns. A solar lamp consists of a few light-emitting diodes (LEDs), a solar panel and a small rechargeable battery, encased in a durable plastic shell.
The Economist reports that the price of solar lamps is set to decrease with obvious growing demand as the rate of global population outstrips the rate of electrification.
