This proposal is for the supply, transport by sea, installation and commissioning in of isolated photovoltaic solar systems for 50 villages. 1. Object The purpose of this project is to provide electricity in rural areas of Guinea. 50 villages were chosen in the first phase for the installation of solar systems with isolated storage capacity adapted to the needs of the connected devices. 2. Locations and insolation
