The paper presents the analysis of the production of electric energy from 10 kWp grid connected photovoltaic system at Technical University – Gabrovo. The photovoltaic system is connected to low voltage electricity distribution network and consists of three subsystems.
Measurement of electrical energy generated by PV system is done with three-phase four-quadrant digital electricity meter. It measures active and reactive power exchanged in both directions between the grid and photovoltaic systems. Three single-phase energy meters measure separately the energy produced by each of the three subsystems. Meters are connected through specialized communication devices to the PC. Remote monitoring and reporting of the energy meters is realized, which records produced electric energy by time tariffs - daily, peak and night. Tabular and graphical visualization and analysis of results for several years of operation of the photovoltaic system are shown.
