Solar still distillation is a natural phenomenon on earth. Solar energy heats water in the seas and lakes, evaporating and condensing it as clouds to return to earth as rainwater. Basin type solar still systems replicate this natural phenomenon on small scale and are the most common method for solar water distillation. An experimental investigation on V-type wick solar still with flat absorber is presented in this paper. A two segment still of 1.5 m2 is constructed. The performance of solar still was experimentally tested on typical summer days. Experimental investigations on productivity, efficiency, internal heat transfer are analyzed. It is found that the role of the absorber wick kept has a greater effect in distillate output. A significant aspect of the still observed from the study is low mass flow rate and minimal overflow of saline water as compared to the conventional wick type stills. The fabrication is easy and economical and can be promoted for the rural people.
