Solar freezers for fish traders in Freetown — stock that used to spoil by evening now keeps until tomorrow.

Fish traders at Freetown's markets work without reliable power. Whatever isn't sold by the end of the day is sold cheap or lost. FBE's modular solar freezer units change that arithmetic.

The challenge

Traders cannot justify a diesel generator for a single freezer, and shared cold rooms depend on a grid that is not there. The result is daily spoilage, distress selling and no way to hold stock for a better price. Any solution has to be small enough for one trader or a small group, need no fuel, and survive a market environment.

What we built

  • FBE 250 L solar chest freezers, each paired with a 2 kW FBE solar generator and its own panels.
  • Freezing by day on solar; overnight hold on the generator's lithium battery.
  • Units deployed through FBE's distributor network, with local after-sales support.
  • Shared-use arrangements so several traders can run one unit.

Delivery

Units are supplied as complete kits — freezer, power station and panels — through FBE's distributor channel and set up at the trader's stall or store. No installation crew, no permits, no fuel supply.

The result

  • Traders hold unsold fish overnight at −18 °C instead of selling at a loss.
  • Zero fuel cost; the sun does the work.
  • Ice production for sales and transport.
  • A model FBE is now taking to other coastal markets in Sierra Leone, Nigeria and Ghana.
