“…At the same time, various agricultural applications of solar energy are discussed, such as solar seawater desalination system, solar pumping system, solar crop drying system, etc. Suraparaju, Sampathkumar & Natarajan 70 believes that the current trend in solar desalination is to couple solar stills with photovoltaic systems for more benefits. This integration of photovoltaic and thermal (PV/T) technologies with desalination systems satisfies not only the need for clean water, but also the needs of remote and rural areas where electricity is in short supply.…”

In fact, current water supplies due to natural constraints or lack of infrastructure (or both) cannot be provided in a sustainable manner for all increasing and competing uses (e.g. residential, industrial, agricultural). While promoting Penghu's low-carbon islands, in a water-scarce environment, it is the motivation of this research to take into account the development of water resources and lower energy consumption costs. The seawater desalination plant water production technology is improved, the cost of water production is reduced. This research uses a genetic algorithm (GA) to optimize the recovery rate to solve the minimum Specific energy consumption (SEC) value, and then, according to the required water production, the optimal flow rate of raw seawater of the high-pressure pump is obtained, so as to minimize the energy consumption of the reverse osmosis (RO) system. The energy recovery device has a great effect on reducing the energy consumption of the RO system, and it can be seen from the results that the higher efficiency does greatly reduce the energy consumption of the SEC and water production under the different energy recovery device efficiency. Calculated using genetic algorithms, and the SEC is 3.275 and the recovery rate is 45.1%, and the water production energy consumption is 2.35 kWh/m3. Scheme B changed the efficiency of the energy recovery unit to 97.22%, resulting in a SEC of 1.819 and a recovery rate of 25.3%, and a water production energy consumption of 1.31 kWh/m3. Finally, challenges and research gaps are also proposed.

“…The solar still is an uncomplicated system in design and fabrication. Also, it is easy to operate and can be effectively adopted by less skilled operators for desalinating seawater (Sharon & Reddy 2015;Mohsenzadeh et al 2021;Mu et al 2021;Natarajan et al 2022a;Suraparaju et al 2022b;Thakur et al 2022). However, the daily productivity of the solar still is relatively low and many kinds of research are currently being undergone to augment the overall yield through several modifications such as energy storage, natural fibres, and condensing units (Arunkumar et al 2021;Chauhan et al 2021).…”

The freshwater production in a conventional solar still (CSS) is very less and it can be enhanced by either enhancing evaporation or condensation rates or both in the solar still. Therefore, the current investigation focused on enhancing both the evaporation rate in the absorber basin and the condensation rate over the top glass simultaneously. In this regard, the evaporation rate is enhanced by using a hollow-finned absorber basin with energy storage and novel pond fibres in the absorber basin. Likewise, the sisal fibre with a water dripping arrangement is utilized for enhancing the condensation over the top glass. The investigations on the CSS and the modified solar still (MSS) with hollow fins and energy storage, pond fibres, and sisal fibres are conducted to analyze the effect of energy storage and natural fibres on the distillate production. It is observed that the water temperatures of the MSS are increased by 12% and the glass temperatures of the MSS are reduced by 30% relative to the CSS. The outcomes reported that the productivity of the MSS is enhanced by 126%. Furthermore, the cost per litre (CPL) and the payback period (PP) of the MSS are 38.5 and 49.3% lesser than the CPL and the PP of the CSS, respectively.

Water is a vital component of human survival. Drinking water is scarce in several large provinces around the world. Only saline water, which may be demineralised and utilised for drinking, is available in this situation. For extended journeys, normal water is required in boats and submarines. Self–demineralised equipment is usually installed in vehicles, but it consumes more conventional gasoline and is, therefore, more expensive. To address this problem, solar still can be used, which has the primary aim of converting seawater into consumable desalinated water. In this work, a solar still with phase change material (PCM) – RT58 which have better thermo-physical properties has been incorporated and investigated for thermo-economic performance. It is observed from the results that the RT-58 PCM achieved a greater yield compared to conventional solar still (CSS) without any PCM as an energy storage material. The productivity of solar still with PCM is increased by 46% relative to CSS. Also, the economic analysis revealed that the solar still with PCM is more economically viable than CSS in terms of cost per litre production of freshwater and payback period.
