An article published on Bloomberg on July 28, 2015 profiles M-Kopa, a Nairobi-based provider of solar-lighting systems. “Customers agree to pay for the solar panel with regular instalments. M-Kopa then monitors payments that are made using a mobile-phone money-transfer service. If payments are missed, the panel is deactivated via the SIM card. Once the panel is paid for, clients keep it.”
The article’s byline reads, “Solving Africa’s Electricity Problem.”
