Sažetak
In recent years, there is an increasing number of photovoltaic systems connected to distribution networks, all over the world. It is to expect further increase in the future. This work focuses on analysis of a photovoltaic system with three singlephase inverters connected to the electric grid. The work also presents Photovoltaic laboratory system in KONČAR-Electrical Engineering Institute, whose purpose is to compare the differences in energy production of three PV strings with and without tracking system. Financial analysis projects the return on investment, and cumulative gain for each of the strings separately. In addition to the economic viability the building of photovoltaic system has its value in terms of security of electricity production and the immeasurable value in preserving nature. Photovoltaic systems often use single-phase inverters. The disadvantage of such systems is an asymmetrical unbalanced delivery of electricity to the distribution network. This means that the currents in individual lines are unbalanced which leads to the unbalanced three-phase power generation.
