Abstract

The primary purpose of this study is to create a thermal model of a photovoltaic module which is usable under real climatic conditions in the Central Europe region. The system for temperature measurements of the photovoltaic module was designed and built at the Department of Physics SUA in Nitra. The climate data utilized in the present study were obtained from a weather station. The measurements were performed during the summer on PV modules. The results obtained indicate that the response of the module temperature is dynamic with changes in irradiance and module temperature, particularly during the periods of fluctuating irradiance. Mathematical descriptions of the obtained time-temperature and time-irradiance relations were made on the basis of the experimental results obtained. A second-degree polynomial function was established for every graphical relation obtained with relatively high coefficients of determination. The temperature model of PV modules was generated after fitting the experimental results to real dependencies and correlation analysis values.
