Low Cost Multiple Output Concentrated Solar Energy System (CSES)
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 8
Abstract
Low cost multiple output concentrated solar energy system is centred towards the maximum utilization of solar energy, both direct and diffused radiations producing output as a combination of Electricity, Hot water and steam . This design of CSES consists of whole system divided into three parts. First part, the centre of the system features the concentrating Fresnel lens with a copper pipe at its focal. Second part is the reflective walls which focuses the sunrays towards photovoltaic cell at bottom. This part further includes heat exchanger made of copper pipes arranged below the photovoltaic cell to extract waste heat energy. In the third part, for utilizing the scattered and diffused radiations, an assembly consisting of waste PVC pipes and bottles are used. As well as a stand along with manual tracking is used for better efficiency. The main aim of this research work is to prepare a system which produces all, electricity, hot water and steam for various utilization at low cost in rural areas and industries. This would reduce the excessive usage of other fuels and would help during the peak periods as a substitute at low cost. In summer this CSES system generates a maximum of 6.8w electricity, steam of 115℃ and hot water of 65℃. The solar radiation varies as per seasons and so variation in thermal efficiency is observed. This research paper involves the study of the construction of CSES system, it’s thermal efficiency in different months, inclination angle with sun and various other aspects.
