Results of Experimental Study of Photovoltaic Installation Based on Thin-Film Panels for Integration on Facade of the Building

Abstract

This article presents the results of experimental studies of a photovoltaic installation (PVI) based on thin-film cadmium telluride panels. The aim of the work was an experimental study of the PVI for integration on the facade of the building. For the research, PVI was prepared by assembling photovoltaic panels (PVP) into window blocks. This installation consists of two parts. The design of the first part PV1 allows to change the angle of inclination relative to the horizon. The second part of PV2 has a strictly vertical orientation. The research was conducted in the geographical conditions of Tashkent in July-August and September-November 2025. The experimental results showed a significant dependence of the performance of photovoltaic installations on the angle of inclination to the horizon, on the seasons and weather conditions. For vertically installed PVP, the use of reflective devices that concentrate the sun's rays proved effective in the summer. According to preliminary studies, the use of reflectors has increased the flow of solar radiation to the surface of photovoltaic panels by an average of 25%, and electricity generation by 14%. In the summer, the optimal PVP tilt angle for the geographical area under study was 33°. The second stage of the research was the study of PVI's work in the autumn period of the year. The measurement results for this period showed that the PVP power at vertical orientation was 16% higher than the PVP power at an angle of 33°, and 13% less than the PVP power at an angle of 60° to the horizon. The conducted experimental studies make it possible to determine the geometric and energy parameters of PVI for optimal integration on the facade of the building.
