Abstract:

In this study, we presented an analysis of the performance data collected between January-July 2018 of the photovoltaic solar power plant with an installed power of 1.036.8 kWp in the province of Elazığ. The current plant has a fixed inclination of 30° to the south, each of which consists of a total of 192 series consisting of a series connection of 20 FV modules. The plant has 3840 270Wp polycrystalline solar panels, and 24 36 kW string inverters have been connected to the network. The production data obtained from the plant and the simulation data obtained using the PVsyst program are compared with each other. The estimated and estimated annual energy output of the plant was identified as 961.15 kWh/kWp and 919.15 kWh/kWp respectively. A low percentage difference of 4.52 percent between the performance values is an indicator that the simulation results provide reliable data about the facility. Measured weather data showed that when simulation was carried out, the estimated production value was 1% higher than the actual production value. When these data are used as input in the PVsyst simulation program, the energy value produced has been found to be approaching the energy value in the measurement system.
