Abstract

The main objective of this work is the design and development of non-imaging solar collector systems for heating purposes. The aim is to increase the efficiency of the Compound Parabolic Concentrator CPC, by proposing a novel modification to the absorber. A modifications have been undertaken in the absorber design by introducing two cavities in the most appropriate location. The new design has been tested and compared with conventional designs to prove that the novel design of CPC with a dual cavities is ameliorate, as it was able to increase the efficiency considerably and at the same time reduces the heat losses. In this paper a comparative experimental results for CPC with two different absorber. The experiment was done under a real condition of sun. The comparative results was for the efficiency of each collector.
