Climate change is one of the most significant environmental problems and is affecting the entire
global population. Renewable sources of energy (RES) are vital to deal with this problem. Solar
energy, especially photovoltaic (PV) technologies, is one of the most promising renewable energy
sources and is, therefore, one of the fastest-growing industries in this field. Thus, this paper focuses
on the performance analyses of rooftop on-grid PV system in real climatic conditions in Niš (Serbia)
in 2019 and its environmental benefits. Besides, the life cycle assessment (LCA) for the PV system,
based on a case study in Niš, is also given in this paper. Based on this study, energy from PV systems
could potentially be a part of the solution for Serbia’s future energy demands, as well as for the
preservation of the environment and the establishment of sustainable development in Serbia.
