Sažetak
Solar photovoltaic (PV) irrigation systems are usually sized by using measured or modelled meteorological data, such as solar radiation, air temperature and precipitation amount during a year or a certain period. Experiences during sizing as well as during using of such systems show that through the year are some disorders, despite of the using of other available data such as yearly cloud coverage, number of sunny days etc. In such cases, usual statistical parameters as well as trend analysis are not reliable tools for predicting deviations of the PV irrigation system operational functioning. This paper will research suitability of using the Rescaled Adjusted Partial Sums (RAPS) method to determine the existence of such deviations in the given time series (i.e. their deviations or fluctuations) of the solar radiation intensity, air temperature and precipitation amount. On this manner, the existence of certain irregularities of the given time series i.e. input quantities of solar radiation intensity, air temperature and precipitation amounts will be determined. That will define the period of the year in which attention should be paid to the operational functioning of the PV irrigation systems. The presented methodology will be shown on real examples on several locations in the Republic of Croatia where PV irrigation systems are planned to be built. This methodology will contribute to the achieving of systematic sustainability of the PV irrigation systems.
