Indigo provides off-grid solar power to the 1.6 billion people worldwide without electricity through an innovative pay-as-you-go business model. Customers can purchase solar energy credits via SMS that provide lighting and phone charging for a set period of time, saving 50% or more over traditional energy spending. Indigo has already deployed 200 systems across 4 countries in early 2011 and plans to deploy 4000 more systems across Africa in 2012. The company's vision is to energize rural homes affordably without grid connections through distributed, low-power solar solutions.
