The sensitivity analysis of input values in water supply system driven by solar photovoltaic energy

Sa？etak Renewable energy sources and their usage are very actual nowadays, due to greater environmental awareness. This paper deals about the solar photovoltaic (PV) energy, which is used for waterpumping, orfor her using in irrigation. A system which is driven by such energy consists of solar photovoltaic generator and inverter, pumping stations, water tanks and pipelines. Because solar photovoltaic energy has stochastic nature, she also has an impact on all parts of the observed system depending on climatic and technological factors. Due to climatic and technologicalparameters, in this paper, an analysis of the sensitivity of certain parts of urban watersupply system driven by a photovoltaic energy has been made.This will give a more detailed insight into theimportance of individual input parameters due to change of their values, i.e. shows which of these factors affects at least or the most, or indicate which ofthem have proportional and inversely proportional impact to the urban water supply system driven by PV energy
