ABSTRACT
Changing conditions have a significant impact on the efficiency and durability of photovoltaic cells. On photovoltaic modules have also influence such external factors as temperature of the module, which changes during the long exposure to light radiation, wind, pollution and the frequency of rainfall. Parameters of PV modules provided by the manufacturers differ significantly from the results achieved under natural conditions. This work presents the laboratory study on the impact of temperature of the polycrystalline silicon module to the change of generated voltage tested with no load. Research confirms the correlation of temperature increase during the long exposure to light radiation with a voltage drop. At the same time simulation of wind causes the cooling of the module and increase the voltage circuit. Further development of research on the effects of environmental conditions will allow for accurate placement optimization of photovoltaic farms.
