Abstract
Introduction. This article presents the structural design and experimental research results of an innovative device intended for the efficient cooling of photovoltaic modules installed above main irrigation canals using a float-based automatic height adjustment mechanism according to the water level. Methods and materials. The study analyzes the microclimatic parameters, operating temperature, and energy efficiency of photovoltaic modules installed over irrigation canals under the hot and arid climatic conditions of Uzbekistan. Results. Experimental results demonstrated that the operating temperature of modules placed above the water surface decreased by 10-12°C, while the electrical power output increased by 7-16%. Furthermore, it was determined that the natural cooling mechanism caused by water evaporation reduces module degradation and extends their service life. Conclusions. Due to its autonomous operation without electricity consumption, structural simplicity, and high efficiency, the proposed device represents a promising technological solution for the development of solar photovoltaic systems over irrigation canals.
