A solar based water purification system (100) is disclosed. The system (100) includes a housing (102) and a central chamber (104) placed within the housing (102) for holding non-potable liquid. The system (100) includes a Fresnel lens (106) to cover the housing (102). The system (100) includes a porous hydrophobic membrane (110) placed at a circumference of the central chamber (104) to allow liquid vapours to pass through the membrane's pores towards an inner surface of the Fresnel lens (106). The system (100) includes a plurality of air pumps (114) placed at an inner surface of the housing (102) between the porous hydrophobic membrane (110) and the Fresnel lens (106). The plurality of air pumps (114) direct the liquid vapours in a collection chamber (116) for condensation. The system (100) includes a photovoltaic panel (118) to provide energy to heat the non-potable liquid at night.
