Abstract :
The experimentation on solar absorber and collector is mandatory so as to have their effective utilization in energy intensive sectors. In this connection, experimentation in connection with the characterization of nano carbon and Cr2O3 (60:40) coated solar absorber was carried out. In addition, experimentation in connection with the estimation of efficiency of solar collector and device was carried out as per BIS specifications. The outcomes of experimentation on solar absorber revealed that the crystallite sizes in the carbon and Cr2O3 (60:40) coating on absorber were in nano ranges. The outcomes of experimentation on solar collector and device revealed that the instantaneous thermal performances of solar flat plate collector ranged between 66.9% and 68.6% and energy collection efficiency of solar heating device was 51.4%. As the thermal performances of the solar collector and device could distinctively depend on the optical characteristics of the absorbers, it could be concluded that nano carbon and Cr2O3 (60:40) coated solar absorbers would be effectively used in solar collectors and heating devices.
