Abstract
This work proposes a new type of fractal solar thermal power station (FSTS) based on the use of a fractal solar collector with a modular architecture. The developed FSTS is aimed at supplying local consumers with thermal energy in autonomous and remote areas, as well as for facilities with limited installation space. A key feature of the design is the use of fractal absorbers, whose configuration allows not only efficient absorption of direct solar radiation but also the utilization of reflected sunlight for additional electricity generation. For this purpose, photovoltaic (PV) elements are placed on the rear side of the absorbers, converting the reflected radiation into electricity. The combined use of a fractal collector for simultaneous generation of thermal and electrical energy increases the overall efficiency of solar insolation utilization and contributes to higher energy density of the installation. The article evaluates the efficiency (coefficient of performance, COP) of the FSTS, examines energy losses, thermal balance characteristics, and factors affecting energy conversion efficiency. Additionally, the key advantages of the proposed design are outlined, including installation flexibility, enhanced reliability, and scalability, as well as potential disadvantages related to structural complexity and the need for precise calculation of the geometry of fractal elements.
