The use of solar energy in thermal desalination process is one of the most promising applications of renewable energies. In a solar desalination system, solar energy is utilized for heating salt water and converting it into soft water. A set of the evacuated tube and compound parabolic solar collector mainly get high-temperature performance in the range of 1200˚C-1250˚C. The annual yield is at its maximum when the condensing glass cover inclination is equal to the latitude of the place. The solar desalination system is eco-friendly and popular in rural areas. In the future, there is great scope in research carried out with other developed technologies such as ETC, ETC with heat pipes and multistage solar distillation.
