Photovoltaic cells equipped with a thermal collector can convert solar energy into electrical, thermal and a combination of the two energy. In this research, a linear parabolic concentrator system equipped with photovoltaic cells was simulated with optical in Optic Ray Tracing software for optical simulation and Solidworks software was used for thermal simulation and its results were compared with experimental results. Simulation of the thermal collector was done by the thermal-photovoltaic system with two longitudinal and transverse arrangement of pipe in 4 diameter levels (8, 10, 12 and 14 mm) and three flow rate levels (1, 2 and 3 l/ min). Simulation results of two longitudinal and transverse arrangement of the pipe showed that the thermal efficiency in the longitudinal arrangement was better than the transverse arrangement. Also, the results showed that with increasing pipe diameter from 8 to 12 mm the thermal efficiency changes process was increasing, and from 12 to 14 mm diameter there was no significant change in thermal efficiency. Increasing the flow rate from 1 to 3 l/min increased the thermal efficiency due to the decrease in thermal losses and electrical efficiency due to the lower surface temperature of the photovoltaic cell. According to the simulation results, the system was fabricated with a 10 mm diameter and field experiments were carried out at a 3 l/ min flow rate. The comparison of simulation results and experimental evaluation showed that maximum thermal and electrical efficiency were 61.18% and 12.58% for simulation data and 58.14% and 12.03% for field data, respectively.
