Abstarct: Due to the increasing development of photovoltaic systems in the supply of electricity in different countries, numerous applied researchs have been done to increase the production and efficiency of these systems. In this research, a photovoltaic system integrated with a compoound parabolic reflector is designed, constructed and evaluated. In design stage, it was observed that the parameters related to the reflector, such as acceptance angle and truntaion percentage, have a different effect on the amount of production and the required area of the reflector (which is directly related to the design cost). Therefore, first, with the means of the solar radiation governing relationships and the compound parabolic concentrator geometry governing equations, the relevant mathematical model was created in MATLAB software to evaluate and optimize the important geometric parameters related to the construction of the device. Optimization was performed with the objective function of maximizing the amount of electricity generation per unit of reflective surface, and baxsed on this, the optimal acceptance angle of 25 degrees, the optimal slope relative to the horizon for the whole system was 35 degrees and the truncation percentage was 75. baxsed on these parameters, the reflector was designed and built with a continuous wooden support. The system was evaluated in summer and in Shahroud city. To compare different modes, this evaluation was performed for three modes of simple photovoltaic panel (without concentrator), panel with concentrator without cooling and panel with concentrator and cooling with water simultaneously. The results showed that the use of compoond parabolic reflectors with a concentration ratio of 1.7 in both modes with and without cooling, increased the output power by 10% and 20%, respectively, compared to the photovoltaic panel. The quality of construction and installation of reflectors from the point of view of light efficiency and increasing panel temperature have been two important factors in achieving these results.
