AUTOMATIC DUAL-AXIS SOLAR TRACKER DEVELOPMENT BY USING FRESNEL LENS

Abstract

The worldwide demand for energy is increasing exponentially, while reserves of fossil fuel have begun to deplete. Sustainable energy solutions are becoming more and more common today. Sustainable energy contributesto the efficient collection of energy, efficientstorage and efficient converting energy intowork. Among these sources of renewable energy, solar energy typically offers great potential for transformation into electricity for daily uses, thanks to its availability and low-cost process. The objective of this research is to develop dual-axis solar tracker by using Fresnel lens. The lower energy absorption and seasonal variation dependence on some geographical locations, however, are the big challenges in identifying suitable applications using solar energy as the heat source. In order to overcome this, research into high-efficiency concentration technology for solar energy is necessary and practical. In this research, Fresnel lenses were chosen due to their advantages such as low length, light weight, low-costmass production and flexibility in the capture of solar energy. The overall efficiency of the Fresnel lens solar concentrator is around 51% based on the performance analysis of the Fresnel lens solar concentrator and the production of steam.
