“…Previous studies [3,4,7,[9][10][11][12][13][14] showed a sharp decline in water production after 2 pm due to decline in solar radiation. The conventional solar still (CSS) and active and passive solar stills cannot produce steady amount of water once there is a reduction in solar radiation.…”

“…A higher experimental productivity of 3.77 kg/m 2 d was obtained as compared to the water production of 2.69 kg/m 2 d for the single slope hybrid (PVT) solar still. A thermal analysis of a single slope solar still coupled with optimum number of evacuated tube collector was developed in India [4]. The daily energy and exergy efficiencies of up to 33.05 and 2.5% with the highest output of 3.8 kg/m 2 d were observed with a combination of 10 evacuated tubes and water depth of 0.03 m in the basin.…”

2015): Sustainable potable water production using a solar still with photovoltaic modules-AC heater, Desalination and Water Treatment, A B S T R A C T Solar energy as a sustainable energy source can be harnessed to produce potable water using solar stills. In this work, effort was made to evaluate the performance of a double slope solar still integrated with a 500 W heater to produce potable water. The heater was powered by six photovoltaic modules, which can produce 1.5 KWp and then connected to four batteries with capacity of 150 Ah each. The experiments were conducted over several days in the tropical climate of Malaysia. A black painted steel trough with length 90 cm, width 45 cm, and depth 8 cm was used as the basin of the glass covered double slope solar still. A comparison of the cumulative water production between the conventional solar still (CSS) and solar still with PV-Heater (CSSPVH) was done. The CSSPVH was found to be more effective; producing about six times the amount of water produced by the CSS. Mathematical models derived based on energy balance studies of CSSPVH, were used to carry out simulations to verify the experimental findings. The energy balance equations of condensing cover and the basin water of CSSPVH were developed as well. A good agreement was found between numerical and experimental productivities of CSSPVH. An expected increase in water production of up to 16 kg/m 2 per 24 h was obtained using CSSPVH. Therefore, CSSPVH is an effective design to produce sustainable potable water, even in areas with very low daily solar radiation intensity, due to its ability to store solar energy. In addition, some tested water quality parameters indicate that water produced from solar stills meet the WHO standard for potable water.

In this present work, the lower basin is connected to the conventional vacuum tubes, hence the temperature of water remains higher throughout the day and the distillate output also remains higher and always releases the latent heat of condensation to the upper basin for heating of water and enhancement of the distillate output. In this research paper, the double basin solar still with vacuum tubes fabricated wastested in climate conditions of Mehsana, (23.6000 • N, 72.4000 • E), Gujarat, with three different water depths 0.03, 0.04 and 0.05 m inside the lower basin and upper basin for one year time period of January 2012 to December 2012. It has been found that the double basin solar still with 0.03 m depth produced more compared with 0.04 kg and 0.05 m. It has also found that the average distillate output of the present system was found to be 8 with the monetary value of produced water being around 0.37 Rs/kg.
