Solar panels sit on the roof of a home powered by M-Kopa solar technology in Ndela village, Machakos county, in Kenya, on Wednesday, July 22, 2015. Customers agree to pay for the solar panel with regular instalments which M-Kopa, a Nairobi-based provider of solar-lighting systems, then monitors for payments that are made using a mobile-phone money-transfer service.
