Sun King

December 2025
Sun King, the world’s largest off-grid solar energy company, has raised $40 million in equity financing from Lightrock, a global sustainable investment platform.

Over the past 18 years, Sun King has built a scaled distributed energy utility model that combines energy generation, energy-efficient appliances, installation, and consumer financing in a single integrated offering, now serving over 50 million people with power and light. The company’s wide range of solar systems serve individual households, businesses, and institutions that have no or unreliable access to grid power. The products range from hyper-affordable solar kits for basic home lighting and phone charging, to multi-kilowatt solar inverter systems that power large residences, schools, health clinics, farms, and commercial facilities.

Sun King aims to deploy more than 50 million additional solar kits by 2030, extending clean, reliable electricity to 200 million people. This expansion will be supported by a significant scale-up of the company’s retail and field operations.

Between 2025 and 2030, Sun King plans to grow its network of shops from 470 today to approximately 1,650 and increase its agent workforce from 45,000 at present to, approximately, 90,000 across the African continent. Sun King’s agents are responsible for last-mile sales, installation, customer support, and product servicing, forming one of Africa’s largest clean-energy distribution and service networks.

The new capital will enable Sun King to expand its product portfolio, leveraging advances in solar, control electronics, and battery science to deliver higher-capacity, more cost-effective systems. Sun King plans to deploy 3.8 GW of new decentralised solar capacity by 2030 — roughly equivalent to the output of three large African coal power stations — delivered directly to households and businesses without reliance on grid infrastructure.

The capital will also support the development of new energy solutions beyond Sun King’s existing solar portfolio, including pay-as-you-go clean-cooking technologies and smartphones as well as productive-use appliances for refrigeration and milling. These solutions are designed to improve health, strengthen local food systems, as well as boost household and small-business incomes.
