In this strip the effect of two glass covers on tubular collector will be investigated, aiming enhancement of cylindrical parabolic solar collectors efficiency. By using glass cover it is aimed to decrease losses and increase efficiency. In order to investigate the changes or losses and instantaneous efficiency, a model was constructed considering all parameters of the structure, optical losses, material properties and outdoor climatic conditions. Results of calculations show that the two-cover system is not more efficient than the single cover system at low fluid temperatures between 0 and 500 K and the efficiency of the two-cover stem is increased at medium fluid temperatures between 500 and 700 K.eninfo:eu-repo/semantics/openAccessParabolic solar collectorsefficiency of collectorssolar energyrenewable energy sourcesArticle26249550210.2339/politeknik.9559191191104WOS:000740192300001N/A
