Company Overview
About Sun King
Sun King (formerly Greenlight Planet) is the world's largest off-grid solar energy company, providing affordable solar lanterns, home systems, and inverters to households and businesses in communities where the electrical grid is unreliable or inaccessible. The company operates primarily across 11 African countries — including Kenya, Nigeria, Uganda, Tanzania, and Ghana — as well as parts of South Asia, serving a combined addressable market of over one billion people living beyond reliable grid infrastructure. Sun King's pay-as-you-go (PAYG) financing model enables customers to acquire solar systems through small daily or weekly mobile money payments rather than large upfront purchases.
Business Model & Competitive Advantage
Sun King has raised over $507M in total funding across 15+ rounds from 14 investors, including recent 2025 milestones: a $156M securitization closed with Citi in July 2025 to scale solar access across Kenya, an $80M conventional debt round in May 2025 backed by IFC and Stanbic IBTC Capital, and a $40M equity financing round from Lightrock in December 2025 to accelerate expansion across Africa and Asia. The company's hybrid hardware-financial services model — manufacturing and distributing solar products while also acting as a micro-lender through PAYG — creates significant customer lifetime value and repurchase loyalty.
Competitive Landscape 2025–2026
Sun King operates a distribution network of over 45,000 field agents and approximately 470 retail shops across Africa, with plans to grow to 1,650 shops and 90,000 agents by 2030. This last-mile distribution infrastructure — built over years in rural markets — represents a durable competitive moat that is extremely difficult and capital-intensive for new entrants to replicate. As climate finance and energy access investment accelerate globally, Sun King is positioned as the category-defining infrastructure provider for off-grid solar electrification at scale.
