The $7 a month plan bringing solar energy to rural Africa

Story highlights

  • Off Grid Electric provides solar energy to homes in Tanzania and Rwanda
  • Plans are financed through microtransactions starting at about $7/month

(CNN)In sub-Saharan Africa, over 600 million people do not have access to electricity -- that's 68 percent of the population, according to the International Energy Agency.

That's because the power distribution infrastructure -- plants and the grid -- is severely underdeveloped, requires large investments to improve and ultimately can't keep up with the growth in demand.
    One solution to the problem is to go "off the grid," mimicking the rapid distribution of mobile phones: over 90 percent of Africans have access to cell phone service -- more than have access to clean water -- but only a fraction of them owns a landline. In the energy sector, the cellphone equivalent is the solar panel, which is easily installed and can provide power to a household or small business.
