EVALUATION OF ENERGY, TEMPERATURE AND ECONOMIC CHARACTERISTICS OF HYBRID COLLECTORS

Abstract

Global trends in the development of green energy actualize the issues of increasing
theefficiency of its generation devices. Since solar panels are the most common type of nontraditional
energy in 26 Ukraine, increasing their efficiency is a priority. This article discusses the option of increasing the efficiency
of solar panels by converting them into a hybrid collector. By conversion, is mean comparing the
characteristics of two options with the same parameters that work as a solar panel and as a hybrid collector.
Water was used as a coolant for the considered hybrid collectors. The calculations were based on the solar
panel heat balance equation. The amount of energy that was absorbed by the solar panel (hybrid collector)
was calculated based on the operating parameters and solar radiation according to refference data from
open sources of information. When compiling the heat balance, it was found that solar radiation falling on
the solar panel causes it to heat up, which in turn reduces its efficiency by 14%. At the same time, the
amount of thermal energy that can be obtained during the summer period exceeds the amount of electricity
generated. Based on the data obtained by solving the heat balance equation, the main indicators were
obtained, according to which the economic efficiency of hybrid collectors was evaluated. As a result of the
assessment, it was found that at the moment the capital investments for their installation and operation are
high and not attractive for mass implementation, therefore, their design requires changes aimed at reducing
the cost.
