TANFON Solar Battery Factory
The King of the Democratic Republic of the Congo has provided a solar energy storage power station system for the village of Bunkeya to meet the electricity needs of 2500 small households in the village. As the village currently lacks access to the grid, the King requested the design of a 1MW solar panel system paired with a 1.8MWh lithium battery storage system to power the entire village.
