  Analysis and Testing Methods for Solar Thermal Evacuated Tube Collector: A Review

  By Avritti Srivastava, Sachin Gupta, Usha Bajpai

  Abstract: Evacuated tube receiver used with parabolic trough collector can be characterized in terms of their heat loss and their optical efficiency. The optical efficiency of the collector involves reflectivity, transmissivity, tracking accuracy, shading by receiver tube surface, shape and absorptance of the material used. On the other hand, receiver tube heat loss includes conductive, convective and radiative losses. Here, in case of evacuated tube, major losses are through radiation, the …
