Energy analysis of the PV farm with a capacity of 140 MW

Recently, there has been a large development of photovoltaics in Poland and in the world. This work shows how the energy profit of a high-power photovoltaic farm changes with the change of the angle of inclination of the panels on the example of a PV power plant project in the Siemiatycze districtin the Podlaskie Voivodeship. In order to verify the energy gain, measurements were made in the PVSyst program for panels with a power of 600 Wp, the spacing of 10 m or 6 m for angles from 20° to 25°. Based on the analysis, the results were obtained, which indicate that with an increase in the angle of inclination in the studied range of angles, the annual production of energy by power plants increases. The difference between the production for the angle of 20° and the angle of 25° is 1010 MWh, which means profits higher by almost 1% per year. on the basis of the selected row spacing and angle, an analysis was carried out, which shows that the average amount of energy generated in a 140 MW installation will be approximately 149 246 MWh. The article also contains an analysis of losses which are generated during the work of PV panels.
