Among all the non-conventional energy sources, solar energy is one of the most promising and renewable alternativesource. Solar water heater can be one of the medium to make best use of this renewable energy for human betterment. Thecurrent work is targeted to examine the performance of solar water heater with different absorber plates viz flat plate, VTrough and compound parabolic concentrator. The developed system is intended to supply hot water for a family at a lowcost. This is regional study and illustrates how selecting a proper concentrator can increase the thermal efficiency of thissolar based system. It was experimentally found that, the solar water heater with compound parabolic concentrator profileas absorber outshines over other two models giving 20.58% more efficient results than V Trough whereas V Trough givesus 20.37% more efficient results than Flat plate. Also, it is found that, less mass flow rate is required for obtaining higherdegree of temperature in case of solar water heater with compound parabolic concentrator.
