Summary: Koolboks, a French-founded startup seen by Accra Street Journal, is bringing affordable, off-grid refrigeration to communities across Sub-Saharan Africa, using solar panels and ice-thermal battery storage to reduce costs and avoid the hazards of generator fuel.
In a continent where over 600 million people lack reliable grid electricity and up to 40% of food spoils before reaching consumers, Koolboks, a French-founded startup seen by Accra Street Journal, is bridging a critical gap—bringing affordable, off-grid refrigeration to communities across Sub-Saharan Africa.
🔋 The Tech Behind the Cool
At the heart of Koolboks’ solution is solar panels coupled with ice-thermal battery storage. During sunny hours, excess energy freezes water in internal compartments, enabling up to three to four days of cooling without sunlight. The units are also equipped with eco-friendly R600a refrigerant, LED lighting, USB charging, and IoT sensors—monitoring temperature, battery levels, and location remotely.

This approach reduces ownership costs by roughly 40% compared to diesel alternatives and avoids the hazards of generator fuel.
🌍 From Start-up to Sector Catalyst
Founded in 2018 by Ayoola Dominic and Deborah Gael, Koolboks pivoted from targeting European campers to rural African markets—now serving 18 countries, with physical operations in Nigeria and Kenya, and expansion underway in Ghana and Congo. The company has sold over 7,000 units, empowering small-scale vendors, farmers, and clinics.
Koolboks also won the prestigious 2025 Start Up Energy Transition Award, recognizing its innovative sustainability model and impact.
💡 Pay-As‑You‑Go: Financing that Works
A lynchpin of Koolboks’ success is its PAYGO (pay-as-you-go) financing model. Customers pay installments—such as $10/month or ₦1,500 daily—over time. Once fully paid, ownership transfers to them. This dramatically lowers entry barriers for low-income households and women-owned micro-businesses, including fish traders who previously relied on ice blocks to preserve stock as gathered by Accra Street Journal
🤝 Partnerships and Scaling
Koolboks’ clients include Orange Energies, deploying solar fridges across 12 countries, and collaborations with NGOs like PREO to empower female entrepreneurs in Lagos. The backing of investors such as Aruwa Capital, Acumen, and GSMA has enabled scaling and the establishment of local assembly in Nigeria and Kenya.
🧭 Why Jungle Solar Fridge Matters for Ghana
For Ghana, Koolboks offers hope on multiple fronts:
-
Food security: Reducing losses in the cold chain
-
Healthcare: Enabling vaccine and medicine storage in off-grid clinics
-
Energy transition: Avoiding reliance on diesel generators
-
Economic empowerment: Supporting small businesses and female entrepreneurs
