    In this work, we present a design of a mathematical model used in the simulation of the behavior of a two-axis solar tracking system (heliostats). This system is used as part of a project of a mini solar tower installed in the region of Ghardaïa. Then we start with the mechanical design of heliostats using SolidWorks software. After that, we went ahead with the realization of this system.

    This paper presents results obtained from monitoring a 28 kWp photovoltaic system installed on the rooftop of a Research Unit in Renewable Energies in the Saharan Medium (URER-MS), Adrar, Algeria. The system was monitored in month June 2017. The analysis shows that the value was in the performance ratio and the efficiency of the PV module, system, and the inverter, were 82.4 %, 13%, 12.6 %and 93.8 % in June 2017 respectively. The average DC/ AC power of the PV array was 147.5 kWh/month and 43kWh/month respectively. The observation and analyses exploitation of the collected data can help to evaluate the performance of the PV system connected to the network in the Saharan area of south Algeria (Adrar).
