“…Extensive studies are also carried out on single slope solar still by reflecting the solar radiation through the bottom absorber as inverted basin studied by Dev et al [23] and Suneja et al [24,25]. Several researchers investigated the integration of active solar still with FPC [26][27][28][29][30][31][32][33][34], Compound Parabolic Concentrator [35][36][37][38], Parabolic shaped concentrator [39], Parabolic Trough collector [40,41], Cylindrical parabolic concentrator [42,43], Evacuated Tube Collector [44][45][46][47], Parabolic Dish concentrator [10,48,49], Concentrator with crescent absorber [50], Solar pond [51][52][53][54], Solar still integration [55][56][57], Hybrid PV/T integrated solar still [58][59][60] for improving the yield.…”

IntroductionGreater growth of population and industries results in shortage of fresh water. Earth is almost covered with a larger water source and smaller land mass. People used to drink large amount of water for their thirsty need. Water available in the form of rivers, lakes cannot be consumed directly without pre-processing, as these need some purification process in order to remove bacteria and undissolved salts. In early days the possible method of getting pure water is heating the brackish water and condensing them back to get fresh water by burning fossil fuels. Due to the exhaustion of coal, crude oil and increases in global warming, the evolution of using renewable energy for getting fresh water evolved during the late 20th century. One of the best energy source applied is solar energy. Source of energy from sun is mostly environmental friendly and non polluting clean energy source. Basin type still is the most aged process of producing fresh water [1][2][3][4][5][6][7][8][9][10]. The fresh water conversion rate from the solar still system is predominantly depends on the solar intensity. The basin water temperature increases continuously due to heat energy emitted from the sun in the form of solar intensity. After reaching the boiling point of water, the water evaporates and it condenses on the solar still condenser cover. The various techniques employed in solar still, to raise the temperature of water and hence increases the productivity was studied from the detailed literatures reviews of Ravishankar et al. [11], Kabeel et al. [12] and Manokar et al. [13][14][15]. From the detailed literature studies it is clear that water temperature can be improved by either feeding waste warm water or pre heat the water by incorporating the different solar collectors or concentrators. Gupta et al. [16] theoretically analyzed the intermittent flow of waste warm water to the double basin solar still similarly same analyses was done by Yadav et al. in single basin solar still [17]. Sodha et al. [18] and Tiwari et al. [19] experimentally investigated the performance of solar still utilizing the warm water from the industry. Tiwari et al. [20] keep up a higher temperature difference between the water and collector cover by increasing the water temperature by flowing waste hot water in the basin and decrease the collector cover temperature by flowing the cold water above the surface of collector cover. This would results in increase in both evaporation and condensation

“…And under field conditions in the natural circulation and forced mode (series and parallel), It had been experimented evaluating performance in order to improve the productivity of a dual slope solar energy solar still [30]. The water pump has been used between solar and photovoltaic (PV) integrated flat-panel collector for re-circulation of water during the collectors and converted into solar still, from Fig.…”

Abstract:Photovoltaic modules can generate more electricity when receives a big quantity of solar radiation, but the efficiency of (PV) modules will drop when the temperature of solar cells is high. Therefore, reducing the high temperatures of (PV) modules will contribute to increase the electrical efficiency of (PV) modules by extraction the thermal energy associated with the PV modules and achieve an appropriate conversion efficiency of (PV). The aim of the study in this paper is to recognize the performance of hybrid (PV/T) systems in different places, conditions, module designs which can be used in household applications, hotels, etc. Aiming to supply of electricity and thermal energy. The study indicates to use of cooling technique (water or air) to cooling (PV) modules will contribute to a large extent to strengthen the work of solar cells and the efficiency of (PV/T) system as well. And the rate return of the system of electricity and thermal energy will increase, especially when the hybrid photovoltaic/thermal (PV/T) solar systems were properly designed and the conversion rate of absorbed solar radiation for (PV) modules will increase as well.
