Solar Concentrator Engineering Design SWx 700-250

摘要

The article provides an overview of the effects and phenomena that can be used to accomplish the development of a solar concentrator, the choice of the given physical phenomenon (specular reflection) is presented. Further, technical solutions for this task are developed, the choice of a specific technical solution is justified on the basis of the customer's technical capabilities, and the calculation of geometry of elements of the concentrator on the basis of creation of the course of parallel rays falling at angles from 20° up to 90° is given. In conclusion, the efficiency of the concentrator on the basis of an increase in the effective area of the light capture is calculated; the calculation of the error of the obtained results is made. From the performed constructions and calculations, it follows that for direct solar radiation (20°-45°), the average increase in the values of the effective working area of the light capture was 1.518 times or 51.8%. For diffuse solar radiation (20°-60°), the average increase in the values of the effective working area of the light capture was 1.394 times or 39.4%.
