Abstarct: Today, due to the increase in energy demand and many problems, fossil fuels are one of the best alternatives introduced to photovoltaic solar systems. The numerous advantages of photovoltaic systems have caused these systems to attract the attention of researchers and move rapidly in the development path. In most researches, researchers are looking for ways to improve the efficiency and output power of photovoltaic systems. Nowadays, due to the increase in energy demand and the many problems of fossil fuels, solar photovoltaic systems are one of the best alternatives introduced. The numerous advantages of photovoltaic systems have caused these systems to attract the attention of researchers and move rapidly in the development path. In most researches, researchers are looking for ways to improve the efficiency and output power of photovoltaic systems. In this study, a solar system including a photovoltaic panel equipped with a compound parabolic concentrator with a concentration ratio of 3 has been designed in order to increase the output power of the solar panel, but previous research has shown that the use of solar concentrators The reason for the increase in radiation on photovoltaic panels is the increase in temperature, and the presence of a cooling system for these panels becomes necessary. For this reason, in this study, phase change materials were used to control and reduce the temperature of the panel, and also to use The heat stored in the phase change materials is used from thermoelectric generators to produce excess electricity. After the design of the concentrator and the construction of this system, tests have been carried out in two seasons, winter and spring, in Shahrood city, where various parameters such as the output power and the temperature of the system panel have been measured in comparison with a simple solar panel in the same environmental conditions. The results show that the constructed laboratory system was able to increase the output power by 111.3 percent in the spring season and 85.65 percent in the winter season compared to a simple solar panel.
