In this communication, existing design of single slope solar still has been modified, developed and tested. The modifications in conventional single slope solar still include (i) inside walls painted with white colour and (ii) attachment of water sprinkler with constant water flow rate of 0.0001 kg/s on the glass cover. The performance of modified single slope solar still has been evaluated and compared with conventional solar still. Experiments have been carried out on both modified and conventional single slope solar still for 05 cm water depth in the month of April at Jabalpur (Latitude 23°18′ N; Longitude 79°95′ E) India. The distilled water output was recorded 2940 ml and 3541 ml from conventional and modified solar stills respectively. Water productivity or yield of single slope solar still is increased by 20% from above modifications. The overall efficiency is increased by 21% over the conventional solar still.
