INCREASING THE EFFICIENCY OF SOLAR ELECTRICAL PANELS BY CONVERTING THEM INTO HYBRIDS

Abstract

Non-traditional energy has recently been more and more integrated into the modern energy system of Ukraine. The geographical location opens up great opportunities for the development of manyrenewable energy sources, including solar energy. In particular, Ukraine has already built some of the world's largest solar photovoltaic plants. However, their use is largely effective due to government subsidies in the form of a "green tariff" and other measures taken by the country's government. If these subsidies are reduced or eliminated, the use and construction of new such plants may be on the verge of recoupment. One of the main ways to increase their competitiveness is to increase the efficiency of using existing stations and introduce a universal low-cost solution for projected solar stations. The increase in the efficiency of solar photovoltaic modules is limited not only by design features, but also by the features of their application. At maximum illumination during the year, the most intense heating of these panels occurs. According to the technical characteristics of individual panels, the decrease in their effectiveness depends on their temperature coefficient. Direct cooling of the panels is an effective way to reduce the effect of this temperature coefficient. To improve these photovoltaic panels, it is proposed to turn them into a hybrid collector. To do this, a special transparent screen with a coolant circulating inside is fixed on the surface of the solar panel. The external arrangement of the screen offers a number of significant advantages over existing commercial hybrid collector models. Cooling the panel with this screen can result in a relatively large increase in power generation due to the intense cooling of the surface and the semiconductor elements themselves.
