  7. Abstract:
  8. Nowadays energy consumption increases in our daily life and incredibly enhancement of growth rate can be seen recent years. Hence, the use of renewable energy is prioritized. Solar energy is one of the choices because it is free and available. In this research, it has been tried to get electrical and thermal power at a reasonable cost both during the day and night. The system is equipped with a linear parabolic concentrator with a collector installed in the center of the concentrator which has been installed on its faces photovoltaic cells and thermoelectric modules, and five different systems have been tested with different components. Also, the paraffin has been used as a phase change material within the trapezoidal channel, which, during the night, returns stored energy throughout the day to the outside of the system and generates electrical power. The most important part of this research is the direct conversion of thermal energy stored in paraffin into electric energy by thermoelectric that have not been done in previous works. The best system in terms of overall efficiency, the system has photovoltaic cell and thermoelectric module simultaneously with an external glass coating that has a total efficiency of 34%, which has a share of electrical efficiency of 6% and a thermal efficiency of 28%
