Environmental and embodied analysis of partial shading pyramid solar still

The novelty of this research is shading position in the transparent cover of partially shaded pyramid solar still. The square pyramid transparent cover is used as top cover of partially shaded pyramid solar still. The square pyramid has four sides and each side named as per the direction. Each one of the sides is shaded in the square pyramid transparent cover. The single side or direction shaded is known as 25% of shading in the transparent cover. Similarly, two sides are 50%, and three sides are 75%. Totally, fourteen configurations of experiments are conducted in the partially shaded pyramid solar still for improving the freshwater yield. Fifty per cent of shading in the transparent cover produced higher freshwater yield compared to 25 and 75%. The partial shading increased productivity of freshwater yield by reducing 4 °C of transparent cover temperature compared to conventional pyramid solar still. The north and south direction shaded (50% of shading) produced 4% higher freshwater yield compared to conventional pyramid solar still. The embodied analysis is studied for partially shaded pyramid solar still. The lifecycle conversation efficiency is around 38%, and CO₂ mitigation is 34.1 for 50% shading of partially shaded pyramid solar still.
