ABSTRACTSolar energy is one of the cleanest forms of renewable energy resources. The conventional solar collector is a well established technology which has various applications in water heating, space heating and cooling. However, the thermal efficiency of these collector is limited by the absorption properties of the working fluid, which is very poor for typical conventional solar flat plate collector. Recently the usage of nano fluids, which is basically liquid- nano particle colloidal dispersion as a working fluid has been found to enhance solar flat plate collector thermal efficiency by 30 percent.

An effort has been made to present a comprehensive overview on thermal performance and improvement of solar radition for a solar flat plate collector with a heat exchanger setup using copper oxide nanofluids.The experimental setup works under the principle of forced convection.

Enhancement of thermal performance and solar radition in the solar flat plate collector with the usage of nano fluid is to be discussed.
