Optimisation of PV system energyefficiency with take into account technical conditions

Abstract

This paper considers the rates of increase in the installed capacity of photovoltaic systems in Ukraine and in the world according to the International Renewable Energy Agency (IRENA) and nternational Energy Agency (IEA). A comparative analysis of the technical characteristics of monocrystalline photovoltaic modules operated in the Czech Republic and Ukraine under similar meteorological conditions is presented. Possible reasons for the decrease in the energy efficiency of photovoltaic modules and ways to solve them are onsidered. It is established that biological corrosion reduces the energy efficiency of the photovoltaic module and initiate the development of other defects.
