The project aimed to demonstrate cost effective time shift of solar energy. This project proposed to install a hybrid energy system consisting of solar PV and a Vanadium Redox Flow Battery at a site in South Africa currently with weak grid connection and back-up diesel generator. Addition of VRFB Energy Storage System enabled storage of power generated by the PV until it is needed, thereby eliminating the demand mismatch between time that power is generated and time that power is needed, a major barrier that prevents further penetration of renewable energy in Sub-Saharan Africa, as in other parts of the world. Elimination of this mismatch reduced reliance on unreliable grid power and back-up diesel generator, thereby reducing CO2 emissions.
