Performance analysis of inverter types used in solar power plants and detailed feasibility assessment for plants installation

PV systems are systems that produce depending on solar radiation but are adversely affected by temperature increase. The reason why PV systems produce more in summer is that the radiation is high. If a lower temperature environment is provided with the same radiation value, more production will be made. Another external factor affecting the efficiency of PV systems, such as temperature, is shading. In case of shadows on the PV panels, the production is seriously reduced. Among the factors that affect the system efficiency of Solar Power Plants, there are many factors such as PV panels, inverters, construction design, site layout, DC-AC cabling, DC/AC ratio of the plant, PV panel placement and slope. Before the installation of the PV systems, the field analysis should be done and then the feasibility study should be done. With the feasibility study, the plant to be installed should be analyzed from many aspects such as material selection, site layout design, PV panel - inverter installations. In this study, shading analysis, PV panel inverter loading calculations were made with 3D modeling using PV*Sol program and system efficiency was obtained according to these analyzes. The simulation report of the program was compared with the fields with real production values and it was seen that the results obtained were in great agreement. Thus, it is aimed to obtain the optimum design model by creating different variations for the power plants to be installed. In addition, the effects of panel height and inclination on yield were determined.
