Performance evaluation of a photovoltaic system with battery storage in Ghardaïa site (South Algeria)

Algeria has a very important solar potential, especially in the south. The daily energy received for 1 m² is about 7 kWh. This allows considering this energy as an opportunity and a lever for economic and social development. Therefore, the exploitation of this resource in the south of the country, especially in isolated sites is a very attractive solution. The work presented in this article focuses on the design, implementation and monitoring of a photovoltaic (PV) system with energy storage, for electricity supply of a household located in the town of Ghardaïa, southern Algeria. A survey based on energy consumption and load profile was developed. Models of PV system components are too presented. Also, the component of the global irradiation on the inclined plane is measured. This system was installed and fully instrumented in order to evaluate these performances. The experimental results show that this system meets the load demand with a low failure rate.
