Experimental Study of a Thin-Film Photovoltaic Thermal Battery in Natural Conditions

This article presents the results of an experimental study of a photovoltaic thermal battery (PVTB) and a photovoltaic module (PVM) based on a thin-film structure installed on the heliopolygon of the Department of Alternative Energy Sources (AESs) of Tashkent State Technical University. A brief review of research on PVM cooling technologies and the creation of PVTB installations has been conducted. The data from the experimental study were processed. The dynamics of changes in the external parameters and characteristics of PVM and PVTB are presented graphically, as well as a comparison of the values of the corresponding parameters are given in tabular form. According to the results of the conducted research, the surface temperature of the PVTB decreased by an average of 6.3°С relative to the temperature of the PVM. Due to the developed module cooling technology, the electrical power of the PVTB compared to the power of the PVM increased by an average of 5.3 watts or 10.3%. According to experimental data, 122 L of heated water was produced during the time of the experiment from a useful area of 0.7 m2 of PVTB, with an average temperature of 38.1°C. This installation allows for simultaneous electricity generation and water heating. These advantages create conditions for the use of this installation in the power supply and heated water supply of household needs of consumers.
