Abstract
This paper deals with the use of solar energy solar installation. Taking into account the fact that the volume of traditional fuel energy is not significant and limited, it is important for the present and future generation to introduce new progressive ideas concerning alternative changes in the fuel energy complex in the prism of environmental education. The issues of energy efficiency of alternative fuels in Ukraine is more acute than in the world. The reasons for this are outdated technologies, the exhaustion of resources, the use of fixed assets for electricity and heat generation, which together with low fuel efficiency leads to significant emissions of harmful substances. The use of solar energy in Ukraine will make it less dependent on fluctuations in fuel prices. It is known that, solar installations are often characterized by complex structures or low utilization of the useful space, require complex electro mechanical systems and guidance mechanisms. Currently, there are a significant number of solar collectors, different design and technical and economic indicators. Environmental friendliness and economic benefits of these systems remain the main issue during installation. The paper describes an analysis of the efficiency of the solar heat supply system with a window solar collector which is containing a metal heat exchanger structure. The paper presents data on changes in the heating temperature of the heat carrier in the window solar collector. Instantaneous specific heat capacity of 0.015 m3 accumulator tank acquires a growing trend and varies from 5 to 563 W/m2 in conditions of constant solar radiation of 900 W/m2. The efficiency of the use of the window solar collector reached 62% under the intensity of radiation 900 W/m2 and with the volume of the accumulator tank V=0,015 m3 in the solar heat supply system
