When most solar companies launched across Africa in the last decade, the business model was relatively straightforward: sell panels, install inverters, and move to the next customer. But for WiSolar founder Tonye Irims, that approach always felt too small for the scale of Africa’s energy problem. Across cities like Lagos, Johannesburg, and Cape Town, businesses were burning through diesel budgets while households struggled with unstable electricity and rising power costs. Solar technology existed, but adoption remained limited because the systems were expensive, fragmented, and heavily dependent on upfront capital. For Irims, the opportunity was not simply about renewable energy. It was about redesigning how electricity itself could be accessed across African markets.
That idea became the foundation for WiSolar in 2016. Instead of operating as a traditional solar installation company, WiSolar introduced a prepaid solar electricity model designed to function more like a digital utility platform. Customers could access electricity through flexible payment systems, monitor usage remotely, and recharge power directly from their devices. The company positioned the experience as something closer to buying airtime or mobile data than making a long term infrastructure purchase. That distinction helped WiSolar stand out in an industry where many providers still focused heavily on one time hardware transactions. WiSolar Official Website
Over time, the company evolved from a clean energy startup into something broader. WiSolar’s business increasingly sits at the intersection of climate tech, infrastructure, and fintech. Through its WiGo platform, customers are able to manage solar systems, track energy performance, and access prepaid electricity from mobile devices. The platform also supports remote monitoring and payment flexibility, reducing some of the friction that has historically slowed solar adoption across African markets. Internally, this appears to reflect WiSolar’s larger ambition of becoming embedded within how electricity is distributed and consumed across the continent rather than simply selling solar products.

That strategy is beginning to attract international recognition. In 2025, WiSolar was recognised for the second consecutive year on the Financial Times Africa’s Fastest Growing Companies ranking, a list produced in partnership with Statista that tracks high-growth businesses across the continent. The recognition placed WiSolar among a growing class of African startups building infrastructure-focused businesses rather than lightweight consumer applications. For the company, the ranking reflects years of expansion across Nigeria and South Africa as demand for alternative energy solutions continues to rise. Financial Times Africa Fastest Growing Companies
But internally, WiSolar’s ambitions appear far bigger than growth rankings. The company has increasingly used this momentum to push into new operational areas tied directly to Africa’s evolving energy economy. Recent expansion efforts include growing merchant onboarding networks, expanding financing access for homes and SMEs, increasing battery deployment systems, and scaling partnerships with developers and third party installers. With over 500 accredited and vetted partner installers on the WiSolar platform nationwide, the company has been able to scale more seamlessly while improving customer experience and speeding up after sales support. The model is also contributing to green job creation for electrical and solar engineers across the country. Reports linked to the company’s Financial Times recognition also highlighted strong revenue growth between 2021 and 2024, providing WiSolar with additional leverage as it expands into newer markets and deeper operational layers.

One of the company’s most aggressive expansion plans involves scaling prepaid solar electricity access across thousands of homes and businesses in Nigeria through its Power Purchase Agreement model. The goal is not simply to increase installations, but to reduce reliance on unstable grid electricity and diesel powered systems while making solar adoption operationally easier for customers. In practical terms, WiSolar is betting that Africa’s next generation of energy companies will function less like hardware vendors and more like utility platforms layered with software, financing, and digital payments.

That positioning is becoming increasingly relevant as energy instability continues affecting productivity across African economies. For many SMEs, power reliability remains one of the largest operational challenges to scaling efficiently. Diesel costs continue rising, national grids remain inconsistent, and many businesses are now actively searching for predictable alternatives that do not require overwhelming upfront costs. WiSolar’s prepaid approach attempts to solve both accessibility and affordability simultaneously. By allowing users to consume electricity more flexibly while avoiding heavy installation costs, the company is gradually building around a deeper behavioural shift in how energy is consumed across African cities.

Founder Tonye Irims has consistently framed WiSolar’s mission around democratising access to clean energy across Africa, but the company’s recent expansion signals suggest something larger is unfolding underneath. WiSolar is no longer just competing within the solar market. It is positioning itself within Africa’s broader infrastructure conversation alongside fintech, logistics, and connectivity companies reshaping how cities operate. Some of the continent’s fastest growing startups are now building underneath the systems people rely on every day — payments, mobility, internet access, and increasingly, energy.

For WiSolar, the Financial Times recognition validates the speed of its growth, but the company’s long term vision appears rooted in something much bigger than rankings alone. The business is not simply trying to participate in Africa’s clean energy transition. It is attempting to become part of the infrastructure powering the continent’s next phase of economic growth. And if WiSolar’s recent expansion plans are any indication, the company believes Africa’s future energy systems will be digital, prepaid, and deeply integrated into everyday life.
