Abstract

A small-scale beam-down solar concentrator with multi-disc is designed. At the same time, the tracking method of the system is proposed in this study. The system has the characteristics that the concentrated sunlight is delivered to the ground and the receiver entrance is arranged upwards. Through the analysis and optimization design of the performance of the primary mirror field and the secondary mirror, the average energy flow density of the receiver can reach 420 kW/m²with the optical efficiency of 87.4% under the design conditions, which provides a technical solution for the development and optimization of the beam-down focus fixed concentrator system.
