Performance of Monofacial and Bifacial Solar System for 5MW grid-connected solar power plant with Fixed Tilt and Tracking: Design, Simulation and investigating the effect of temperature

In this paper, a 5000 kW grid-connected photovoltaic system of Haft-Hoze Natural Park, 7 km southeast of Mashhad City, has been designed and simulated. This power plant is for two monofacial and bifacial systems in both fixed and tilted planes and trackers modes in PVSYST software. It is simulated and designed and the simulation data is compared in both cases. In this paper, the effect of temperature on solar panel performance is investigated first. This work has been done in three stages. At first, by keeping the solar radiation constant, the effect of temperature on the output performance of the panel. In the next step, the P-V curves at different ambient temperatures and changes in solar radiation have been investigated. In the following, it shows the effect of PV panel temperature on PV panel output performance at different intensities of solar radiation. The simulation results of the 5000 kW solar power plant, in a fixed tilted plane for the monofacial system, energy injected into the grid and performance ratio are 8291 MWh and 0.850. The bifacial system, energy injected into the grid, and performance ratio are 8730 MWh and 0.896. In the Trackers mode, for the monofacial system, energy injected to the grid and performance ratio are 9558 MWh and 0.838. For the bifacial system, energy injected into the grid and performance ratio are 10025 MWh and 0.880.
