IMPROVEMENT OF SOLAR CONCENTRATOR STRUCTURE.

Green energy includes solar, wind, geothermal and other types of energy sources generation. The object of this research is solar concentrators. The problem to be solved is related to the development of the structure frame, especially for solar concentrators with flat triangular or square mirrors that approximate a parabolic shape surface. The essence of the investigation is developing and producing several prototypes of solar concentrators that have a low cost of materials but the devices were assembled by hand and therefore the manufacturing cost is sufficiently high. Therefore, it is important to reduce the cost through automation of the solar concentrator production process. To obtain better conditions for future automation, we need to reduce the number of metal structural elements of the solar concentrator. In this case, the automation problem is simpler for its realization. The results obtained are related to the improved solar concentrator structure that can be technologically simpler than the previous one and lighter in weight. The development of improved solar concentrator design and structure can help reduce the cost of assembly and accelerate the solar concentrator assembly process. In the case of mass production, they can be used in practice. The proposed solar concentrators can be used for different applications, for example, green buildings in rural areas, or chemical reactors to accelerate the chemical process of organic waste processing. Another application is to use solar concentrators in combination with agricultural fields. These solar concentrators can be used with small-scale thermal energy storage (TES). Using TES, it is possible to make power plants for green buildings. Small solar power plants can support all the energy demands of residential houses. [ABSTRACT FROM AUTHOR]
