Sun King

Sun King is the world's leading off-grid solar company, designing, manufacturing, distributing, installing and financing solar power systems for the billions of people living without reliable electricity. Over 15 years in operation, it has powered more than 26 million homes across Africa and Asia. The company is fully vertically integrated, handling product design, manufacturing, last-mile delivery, installation and long-term warranty support in-house.

Its product range runs from affordable solar lanterns for off-grid households to multi-kilowatt solar home systems capable of replacing a utility connection entirely. Central to the business is pay-as-you-go solar financing, which allows families to spread payments over time rather than bear the full cost upfront. Sun King has extended over $1.5 billion in solar loans; for about two-thirds of its customers, this is their first access to credit.

Getting products to remote customers relies on a field network of more than 37,000 agents who handle last-mile distribution, installation and warranty service. The company describes its purpose as building the infrastructure that enables communities to participate in the modern economy, with a stated commitment to financial inclusion alongside energy access.
