In this paper, a detail introduction to the manufacturing procedure of the point-focused solar furnace was presented from four parts: focusing principle of the solar furnace, optical calculation process, hardware design and installation and testing. According to the actual needs of users and the local solar energy resources, the illuminating area on the plane of the secondary concentrator and the thermal power could be estimated by self-programmed software. Sequentially, the core components of the solar furnace were designed based on the optics calculation results. The modular design of the heliostat both improved the production efficiency with lower cost and simplified the bracket structure. At the same time, it is more convenient for transporting and installation. Each unit reflector of the heliostat had 12 supportive points, which brought the more benefit when leveling the mirror. The similar modular design was taken when designing the secondary concentrator for the reduction of the manufacturing costs, the ease of transport and on-site installation. Each facet of the concentrator was adjustable which significantly enhanced the adaptability of point focus solar furnace. The feasibility of the design method is verified by prototype development.
