The productivity of the solar still also improves through active method of integrating the still with either a solar heater, solar concentrator or other heating devices. The blacken bottom of flat-plate collector absorb the solar radiation and heat up the liquid that make contact with it. This heated liquid is circular in heat exchanger and gives heat to water in the still. The blacked surface at bottom of the still also absorb the solar radiation and heat up the water in the still. The evaporation water in the still start, and condense at the cooler surface of glass cover. The water droplet slide down under gravity to the drainage. The circulation of water through the flat plate collector is made possible by using pump or thermo siphon operation.
