“…With the integration of photovoltaic solar energy as an energy source for the SWDTP, these solutions are increasingly technically and economically feasible. The changes that make this possible are the reduction in PV initial establishment costs, the improvement in the production capacity of the PV panels, and the improvement in energy efficiency and the PV technology, in general, [39][40][41][42][43][44][45], jointly with desalination processes.…”

Integration of renewable energy sources and water production technologies is a must when facing water scarcity problems in semiarid regions, such as Mediterranean regions. The use of additional water resources and production methods, such as reclaimed water and, more specifically, desalinated water, means present and necessary water resources to introduce in the water balances to attend to water demands within a global warming and droughting scenario. These solutions have the inconvenience of energy/power needs and costs. However, the development of renewable energies like photovoltaic solar energy, with lower and lower costs and greater efficiency, makes these economically feasible facilities, reaching competitive production costs for marine or sea desalinated water by around 50% of reduction in energy costs and 20–30% of savings in final water production cost. This paper presents a practical project or action focused on the integration of renewable energies and new water resources by introducing a Photovoltaic Energy Plant (PVEP) as an energy source to feed a Seawater Desalination Treatment Plant (SWDTP). The PV facility is designed to cover all the energy demanded using the SWDTP during the day, and even studying the possibility of selling the energy production exceeds and injecting them into the energy supply network, covering the needs of buying energy needed during the high period where there is no photovoltaic energy production. Thus, savings related to energy costs and even incomes coming from energy sales mean an important reduction in operation costs or expenditures (OPEX), which makes economically feasible and sustainable the investment and the final price of water produced within the Mutxamel SWDTP. The final reduction cost in water desalination reaches 25% on average.

“…Shanmugan et al 21 carried out the work on the low cost storage materials and improved the yield. Shanmugan et al 22 used novel nanoparticles as basin absorbing materials to enhance the yield of solar still. They obtained a higher yield as well as thermal efficiency of solar still having novel nanoparticles as compared with the conventional solar still.…”

In this current study, a single basin solar still (SBSS) was explored in the climatic state of Patan (23.84° N, 72.12° E) India over March 2019. The SBSS was examined with the use of waste brick magnesia (WBM) for the same amount of water (10 L). For experimentation, three same‐sized SBSS were taken with 3 and 6 kg WBM and without storage materials. It was found that a daytime yield for SBSS of 2.27 L without storage materials was obtained; and this was reduced for SBSS with 3 and 6 kg WBM to 1.96 and 1.75 L, respectively. It has also been noticed that the yield of SBSS during off‐sunshine hours due to the energy storage capacity increased with WBM but the combined (daytime + off‐sunshine hours) yield was found reduced with an increment in a mass of the WBM. It was found that the maximum instantaneous thermal efficiency of the SBSS without WBM, 3 and 6 kg WBM was 60.24%, 45.65%, and 54.26%, respectively. Overall thermal efficiency was also determined and obtained to be higher for SBSS without WBM as storage.

“…It is found that the yield increment of 14.5% associated with the ordinary design. Shanmugan et al [16] thermal model industrialized for an energy and exergy analysis of a single-slope single-basin solar still. Rahmani et al [17] was urbanized for a natural circulation in a solar still and established the distillate yield of 3.72 L/m 2 /day by 45.15% efficiency.…”

The solar thermal applications existing to investigative relationships of absorbing materials of water flowing over glass cover through the influence of PCM and nanoparticles for the enhancement of a single-slope single-basin solar still are presented and discussed. The results are compared with and without PCM and nanoparticles summer days for a conventional solar still. Numerically designed and experimental annotations have been written for the investigative solutions for the temperature of flowing water, glass cover, absorbing materials (FWCW and FWJW) and PCM and nanoparticles basin liner, respectively. The 24 h distillate manufacture rate of the solar still has been enhanced to usage of drip button through pure saline water to absorptive influence of FWCW capability is 70.02% and during (24 hours) daily distillate harvest of FWCW is 9.429 kg/m 2 day, water flowing glass cover influence is 13.37%, respectively. A solar still analysis of Fourier coefficients with (6 to À6) harmonics Fourier series has been used for enhancement, and it is found to be a good representation of the observed variation. It is a good treaty among theoretical and experimental annotations of the structure.
