Performance Analysis of a Grid-Connected PV Park in Ruse, Bulgaria

The sustainable development of the industrial sector strongly depends on its energy supply and efficiency. This study analyzes the performance of a PV park that was installed on the roof of an industrial plant in 2020. Its rated power is 194.93 kWp and contains a total of 565 PV modules. Using the available annual data for the energy production and consumption of the enterprise were performed a number of performance tests. The capacity factor varies from 2.42% during the winter to 21.48% during the summer months, with an average value of 11.54%. Similarly, the performance ratio varies from 52% to 83% for the different months with an average value of 70.44%. The obtained results indicate that the installed PV park is operating efficiently, considering the local climate characteristics.
