More than two thirds of the population in sub-Saharan Africa live without access to electricity. These are more than 620 million people who, as a result, have few chances of living comfort and economic development. The company ARC Power from Rwanda has developed an environmentally friendly, future-oriented and also affordable solution for their power supply. It is based on decentralized mini-grids that are operated in a modular manner using solar energy. This container-based portable solar solution provides rural communities in Africa with alternating current power on a 24-hour prepayment basis. A distribution network will be built throughout the village, consumer electrics will be installed in each house or small company. Results from these projects will be improved health and increased safety for women as well as increased learning success for children.
