“…The wick material act as the porous medium in the absorber basin. The wick material increases more wet surface area, resulting in more evaporation (Fale et al 2021) (Shubhajyothi et al 2020). Sharshir et al (Sharshir et al 2020c) investigated the still with a novel wick-metal chip pad.…”

The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.
