Design and analysis of a high-efficiency, cost-effective solar concentrator system for community solar cooking
Solar concentrating systems are optical systems that concentrate solar energy for conversion into usable energy. Ideally, a solar concentrating system should have the following favourable properties as design criteria: (i) energy-efficient, (ii) cost-effective to construct, and (iii) highly durable even in the presence of variation of high temperature and wind. The cost of energy produced by solar thermal concentrators depends on costs of various materials which make up the system, maintenance costs and obviously the amount of solar energy collected. Serious efforts are currently devoted to making solar collector technology economically more competitive. Existing solar concentrating system designs are challenged by energy efficiency and cost of construction. This is because the installation of the major part such as tracking concentrators, are relatively expensive to construct and maintain. These concentrators are generally mostly composed of relatively expensive metallic material (e.g., steel or aluminium), and moreover these large parts need to track with the movement of the sun. Taking into account all advantages and limitations of all CSP technologies a novel design of parabolic solar collector technology is presented in this paper which is modular and effective. The paper describes a novel 2-stage solar concentrating system. This paper is focused on a low-cost solar concentrating system for collecting and concentrating energy from the sun. The design of a solar concentrating system is (SCS) involves a system of concentrating optics, which makes use of two stages of concentration (both primary and secondary concentrators). Unlike most prior solar concentrating systems, it uses stationary primary concentrators composed mostly of concrete, which has very low-cost. The key design and analysis issues are: optical, structural, and mechanical. The paper provides a detailed description of the design issues of this solar concentrating system. The paper also includes a description of the software simulations executed including CAD modelling and MATHLAB computational simulations to simulate solar tracking of the secondary concentrators to analyse overall performance.
