The article focuses on the use of hybrid solar collectors as one of the ways to increase the efficiency of solar systems in general. The authors consider the design of a solar collector with the arrangement of circulation pipes above the heat-absorbing surface with a transparent coating. A solar system with natural circulation of the heat carrier (water) has been investigated.
The paper focuses on the investigation and the simulation of the efficiency of a hybrid solar collector in a heat supply system consisting of two separate units, namely a heat storage tank and a flat solar collector, which are interconnected by pipelines. The study includes the analysis and calculation of the thermal parameters of the system for one day and the determination of the optimal values of the flow rate of the heat carrier in the solar collector and the mass of the heat carrier in the heat storage tank to achieve maximum thermal efficiency of the system.
