KARIBU Solar Power

Produces modular solar lamps and mobile phone chargers.
2013 SEED Africa Award Winner Clean Energy Dar es Salaam, Tanzania

The modular solar lamp consists of a solar panel, a rechargeable battery or mobile phone charger and a light. Users buy the battery and the light components and pay for the solar panel in small increments. After just a few weeks, they own the solar panel and can charge the battery on their own. KARIBU Solar Power’s “rent-to-own” programme and “pay per charge” model replicate the cash flow for buying kerosene. Costs to users are under USD 1 a day, making the lamp affordable for the 500+ million Africans.

Eco-Inclusive Impacts

KARIBU is making high quality solar lighting and mobile phone charging affordable, allowing also poorer communities to enjoy the benefits of solar lighting and energy.
  • Increasing children’s ability to study and learn at home by providing light after sunset.
  • Improving health and safety, especially for women and children, by eliminating toxic fumes and injuries caused by using kerosene at home.
  • Providing an off-grid lighting solution that relies on renewable energy helping mitigate climate change.
  • Reducing carbon emissions by offsetting on average 100 kg of CO2 per solar lamp per year (including CO2 emitted in transportation of kerosene to the end consumers).
  • Increasing families’ incomes by up to USD 100 every year in savings on fuel, candles and batteries – this money can then be better allocated to healthcare, education and training.
  • Increasing revenues for owners of small local shops through the sale of a profitable and affordable product, using a franchising distribution model.
