Abstract
With the decline of non-renewable energy sources, i.e. fossil fuels, renewable energy sources such as tidal, geothermal, solar, wind, etc., will play a vital role in our energy needs. In the future, the efficient use of solar energy will be of primary importance to replace the conventional energy source. The present study details the utilization of solar energy for desalination of water for domestic purpose. It involves the construction, testing & analysis of parabolic dish collector /reflector for small scale domestic purpose. Ground water is heated from solar radiation directly into the receiver and the generated steam is collected & condensed. The parabolic dish can deliver temperature ranging from 473K to 773K. Direct steam generation results in high thermal efficiency. Overall cost is low & it is not harmful for the environment. The experiment was carried out for one module of reflector diameter of 1.2 meters. Also, the concentration ratio is 20 and the focal length is 0.36m. This Solar based distillation system is optimum to remove minerals & hardness found in ground water and make it suitable for drinking.
