In order to increase the efficiency of PTC, we did an experimental study has been performed based on the design and completion of a 1.8 m × 1.6 m PTC solar collector, with the addition of a flat glass cover in order to maintain the optical properties of the reflector and the glass envelope of dust, and moisture due to wind and rain on the one hand, and to increase thermal insulation and increase the thermal efficiency on the other hand. According to the solar radiation, and climatic conditions of Ouargla, we recorded the temperature of the outlet water and then calculate the thermal efficiency during the day, for different water flows. Where the experimental results showed the effectiveness of the glass cover by increasing the thermal efficiency to 9% during the peak period of radiation solar system (Soudani et al., 2017).In order to extend the results to different dimensions of PTC length and larger mass flows, we prepared a numerical simulation of the PTC model. After verifying the reliability of this model by comparing the numerical simulation results with the experimental results, we record the effect of PTC length and mass flow of water on outlet water temperature.To store this...
