Abstract
Abstract. This work provides a general description of the method of increasing the energy characteristics of solar photovoltaic panels by converting them into a hybrid collector, as well as an economic assessment of the feasibility of using this method and a comparative analysis of efficiency. Due to the increased relevance of autonomous sources of electrical energy in today's society, special attention is paid to renewable energy sources, in particular solar photovoltaic panels. The construction of rooftop SPPs is becoming more and more relevant in the context of modern trends in distributed generation and reliability of electricity supply. Increasing the energy efficiency of solar photovoltaic panels is one of the aspects that harmoniously combines increasing energy sustainability, reliability and autonomy. The essence of the proposed method is to convert any existing solar photovoltaic panel into a hybrid collector through the use of a special device. Due to its design, this device almost does not affect the reduction of the intensity of solar radiation on the surface of the panel, but at the same time it allows receiving heat energy in the form of a heated coolant. Depending on the priority direction of operation of the hybrid collector, it is possible to increase the generation of electrical energy by reducing the surface temperature of the panel, reducing temperature losses, and more fully using thermal energy. Theoretically, it is possible to increase the efficiency of a solar photovoltaic panel by 166% using this method, which is a high indicator. And the specific cost of 1 kW h of energy for this method with full use of thermal energy is 5 times lower compared to existing designs. Key words: electrical energy, photovoltaic solar panels, temperature coefficient, hybrid collector, thermal energy, panel heating, insolation area
