Abstract: Solar water heater is one of the most widely used solar applications. Lot of study has been carried out on the enhancement of the thermal efficiency of solar water heater .In this experimental work the performance of conventional absorber plate is compared with the newly proposed absorber plate having concavities. The results shows that there is an improvement in the heat transfer rate. The heat transfer rate is increased by 5.12%. It shows that the increase in outlet temperature due to the provision of concavities which increase the diffusion area for radiation reducing the reflection losses
