Goodbye generators, hello solar
Full-Power Solar for Homes, Businesses, and Institutions
The Challenge: Damage done by dirty generators
For millions of people across Sub-Saharan Africa, diesel generators are the only fallback when unreliable grids fail — but the costs are staggering.
In Nigeria, more than 22 million small generators fill the electricity gap: they have a combined capacity eight times greater than the national grid’s peak supply, and do devastating damage to the environment. In Lagos alone, 4.5 million generators emit 39 million tonnes of CO₂ every single year.
Across Sub-Saharan Africa, households and businesses spend almost as much on generator fuel as they do on their electricity bills. For example, households and businesses in Nigeria spend $12 billion annually on buying, fueling, and repairing small generators. Diesel costs are rocketing across the continent.
Our Solution: Purpose-built solar alternatives
Sun King provides a range of solar inverter systems that reduce dependence on generators. Sun King’s systems deliver reliable, grid-equivalent electricity: clean, affordable, and uninterrupted.
Each system fits a range of customer needs and budgets, from small households to large institutions, and all are hybrid by design: they draw power from both solar panels and the grid, switching automatically to whichever source is available.
Residential and Small Business Generator Replacement
PowerPlay Pro: our most accessible inverter system. Affordable, compact, plug-and-play — it combines solar, grid, and battery power to run everyday essentials like lights, fans, energy-efficient refrigerators, TVs, and phones.
Residential and Small-Business Solar
Reliable, grid-quality power for small homes and businesses. With battery, storage, and enough output to meet the needs of a standard European flat, these systems run lighting, refrigerators, laptops, and televisions with battery and storage.

Power designed for bigger households, schools, health centres, and businesses. With higher output, these systems can run multiple refrigerators, TVs, laptops, and even air conditioning.
Institutional and Commercial Inverters
Customised, scalable systems for schools, hospitals, supermarkets, government offices, and small industries. Fully designed, installed, and serviced by Sun King to deliver uninterrupted electricity for critical operations.
Modular Solar, Built to Scale
Systems designed to grow with you
Start small, powering essentials first, expand over time by adding panels or batteries. This modular design means customers can increase capacity as their needs change, without costly reinvestments.
Shutting Down Dirty Power
Shift to solar for immediate impact
When solar replaces diesel or petrol generators, the benefits are instant. Carbon dioxide emissions fall sharply, along with particulates and black carbon that damage human health. Communities enjoy quieter streets and cleaner air, free from the constant noise and fumes of generators.
Reliable, Affordable Electricity
Stronger systems, greater growth
Sun King systems deliver electricity that matches — and often exceeds — conventional grid reliability. Hybrid by design, our solar inverter systems seamlessly switch between solar, battery storage, and grid power to maintain uninterrupted service. Even during extended blackouts, our systems keep essential operations running. The result? No lost productivity, no spoiled medicine, or perishable goods, and no compromise on service delivery.
Crucially, this reliability comes at a lower cost. By replacing diesel or petrol generators, our systems cut fuel and maintenance expenses while locking in stable, predictable energy costs. Over time, solar power proves not only cleaner and more dependable than fossil fuel alternatives, but also more affordable, freeing up resources so that households, businesses, and institutions can grow.
Powering Growth and Opportunity
Transformative access to essential energy
For households, reliable electricity transforms daily life. Families can study and work after dark, keep food fresh in refrigerators, and charge the devices that connect them to opportunity.
For businesses, dependable power unlocks growth. Shops can stay open past sunset, entrepreneurs can adopt digital tools, and cold storage or machinery can run without the crippling costs and interruptions of fuel-based generators and the unreliable grid.
For public institutions, reliable solar keeps essential services running. Clinics can operate diagnostic machines continuously, schools can use digital learning tools without interruption, and government offices can deliver services without disruption.
