The major source of water in the earth is ocean, which is of high salinity.To desalinate the saline water large amount of energy have to employed, a renewable energy like solar energy is utilized it will be a promising source for desalination. The main objective of this research is to utilize the FPC solar water heater effectively for solar still productivity enhancement at an optimal cost.Probably its performance will be one of the best for water production in remote, arid to semi-arid, small communities, where fresh water is unavailable. The experiment is carried out in a typical day in a melded climatic condition at Trichy (10°8050'N, 78°6856' E), Tamilnadu, India. The basin water depth is maintained in 0.02m throughout the study. The performance of the setup is studied theoretically and experimentally. It proves that 77% higher yield when compared to the single basin double slope passive solar still.
