To overcome the freshwater crisis, throughout the countries many researches and innovative technologies are going on. But from these researches and innovations major models are still in experimental level. Therefore by reviewing these researches and innovations an attempts has been made to develop a new design of Fresnel lens based solar water heater system. The main objective of this project is to efficient production of hot water and identification of absorber performances on the production of hot water. In this project the use of a point Fresnel lens to concentrate the solar energy on a special designed absorber for the production of hot water. The proper focusing of solar intensity on special designed absorber is achieved with the help of tracking mechanism. Using this setup experiments are carried out by different water samples. The results for solar water heater system by Fresnel lens showed that yield of hot water depends on water flow rate and pressure inside the system. At the end of the experimentation period yield of hot water was from 5-8liters/hour on bright sunny day. From experimental results showed that by providing proper orientation of the absorber i.e. conical shaped coil can achieve maximum hot water than inverted orientation of same coil.
