Generation of electric energy from renewable energy sources is a challenge that has to be carefully envisaged since it represents not only a potentially profitable enterprise but also a source of problems for the complex operation of large electric power systems. The paper presents some aspects of grid-connected photovoltaic (PV) systems, especially the determination of solar potential, selection of PV technology and PV system protection. Finally, some aspects of the impacts due to parallel operation of low voltage distribution network and PV system are presented. Research results demonstrate major indicators of PV system impact on the low voltage distribution network. The influence of PV system operation upon voltage profiles, both for the closed and open loop form of low voltage network operation has been analyzed. Briefly, the fault current contribution impact of PV systems has also been investigated.
