Experimental Investigation and Fabrication of an Evacuate Tube Solar Collector

Use of renewable source of energy has now become of utmost attention. With increasing global pollution and subsequent decrement of global reserves of energy supply is a very crucial factor for environmental protection. Energy Generation from renewable sources like sun and utilization of generated one can optimize the global pollution. In this contrasts this paper presents one of the systems utilizing the solar energy to generate hot water for daily purpose and for industrial purpose. Evacuated U tube solar water heating system is one of the effective methods of solar thermal energy collection systems. The experimental observation is that when the mass flow rate of water as well as the tap angle movement increases then heat transfer rate also increases. It was also observed that when the setup was fixed in north west direction the heat transfer rate increases with respect to time and in south west direction it also increases but highest value of heat transfer rate is at 2 pm and another at 3pm.
