Sun King is an off-grid solar energy company offering solar lanterns, home solar systems, solar inverters, and related appliances. Their mission is to provide clean, reliable, and affordable energy to people in areas with weak or no access to grid electricity. The company uses a pay-as-you-go (PAYG) financing model so that customers can pay over time instead of making a large upfront payment.

Operations & Global Impact

Sun King serves millions of households across Africa and Asia.

It has over 80 million customers globally.

The company was founded in 2007 by two graduates from the University of Illinois.

Its growth is powered by a vast agent network that distributes products, provides after-sales support, and facilitates payments, often through mobile money.
