About solar companies in East Africa

Energy in East Africa is two stories happening at once. The grid story, with geothermal power in Kenya, hydropower across the region and Uganda's recent oil discoveries, is dominated by state utilities and large private operators. The off-grid story is bigger and more entrepreneurial: solar home systems, mini-grids, productive-use solar for water pumps and cold storage, biogas digesters on dairy farms, and clean-cookstove distributors reaching markets the grid will not arrive at for decades.

EABD lists solar installers, mini-grid developers, oil and gas service contractors, hydro operators, biofuel producers, and the equipment importers behind them. Verified profiles let buyers, from a county procurement office to a single homeowner, find an installer near them with a verified track record, and contact them without phoning every advert in a Whatsapp group.

EABD lists Tanzanian businesses across the mainland regions, including Dar es Salaam, Arusha, Mwanza, Dodoma and Mbeya, plus Zanzibar. Verification leverages BRELA and TRA registration where applicable. Buyers and partners can browse by region, by major city, or by industry, with the same verified profile, real-reviews, and direct-contact model EABD uses across the region.
