Affordable power brick innovation energises underserved communities
- Wits University
A pioneering solar power solution co-developed with Wits University is transforming access to energy in underserved communities, one “Power Brick” at a time.
Peco Power, launched through a collaboration between Wits and impact investment partner Mbono, offers a modular, affordable energy system designed to grow with a household’s needs. The innovation was developed with support from Wits Enterprise, which helped shape the commercialisation strategy that led to Peco Power’s spin-out as an independent company. Wits remains a foundational stakeholder in the venture.
At the heart of the system is the Power Brick, a robust 12-volt lithium-ion unit that is solar-ready and grid-compatible. Designed for flexibility and durability, the bricks range from 30W to 200W and can be stacked to scale up power over time. An add-on Inverter Brick allows conversion to 110V or 220V AC, depending on regional requirements.
“The Power Brick is built for African conditions,” says Dorian Wrigley, Chief Executive Officer at Peco Power. “You can start with just enough to run lights, then add more bricks as your energy needs grow without replacing anything.”
To address affordability, Peco Power introduced a Champion Franchise Model, a Rent-to-Own programme over 12, 24 or 36 months. This approach puts sustainable power within reach for communities that need it most.
In Nomzamo, Mpumalanga, a local Early Childhood Development Centre uses the system to refrigerate food and power devices for learning and play, demonstrating the technology’s real-world impact.
“This is more than a product,” says Wrigley. “It’s a collaboration. Wits students and staff have played a central role in bringing Peco Power to life and we hope that partnership continues well into the future.”
From lab to light switch, the project exemplifies the power of university innovation to energise both communities and careers.
