“…Maximum solar exergy efficiency is obtained in April and March and is minimum in July and August. [ 45 ] S.Sreenath et al analyzed the energy, exergy, economic, environmental, energo, exergo, and enviroecono (7E) of the solar PV power plant in seven airport sites in India. For the selected location, energoeconomic and exergoeconomic parameters are of low value and enviroeconomic performance is high.…”

Water is one of the basic needs for all living and nonliving things. It is important to sustain the available water resources effectively for future generations. A lot of studies are employed already to improve the performance of solar desalination systems rather than conventional methods. Subsequently, an experimental approach is proposed with energy, exergy, economic, environmental, exergoenvironmental, exergoeconomic, and enviroeconomic performance of photovoltaic/Thermal (PV/T) solar distillation system using two methods to enhance the fresh water yield production at feasible cost. First is the conventional solar still (CSS) with PV and second is PV with double fan solar still (DFSS) with optimized running time of the double fan, which increases the productivity of the solar distillation system. The results show that average daily energy and exergy efficiency of the system improve with DFSS (19.98%, 1.36%) than CSS (11.74%, 0.36%). The daily yield productivity of CSS is 1.618 L m−2 and is increased as 2.482 L m−2 with DFSS. Average cost of water yield production is also reduced with DFSS and estimated as 0.018$, 0.016$, and 0.015$ for the lifetime of 15, 20, and 30 years for CSS and 0.014, 0.013, and 0.012$ for DFSS. Overall, the proposed methodology shows promising results than the conventional approach.

“…However, 840 M people still lack electricity, and the possibility of grid connection is quite low. Therefore, fulfilling their need through local resources is a feasible solution [2,3]. Many researchers have determined the benefits of the renewable powered hybrid electricity generation for remote locations.…”

Due to the significance of environmental aspects, the modeling of hybrid systems should be performed with the lowest cost and environmental pollution. Therefore, an effective and optimum sizing method can ensure acceptable performance. This paper implements a “technique for order performance by similarity to the ideal solution” (TOPSIS) method combined with the “analytic hierarchy process (AHP)” method to size a standalone system based on techno-economic parameters. For this reason, a survey was conducted to collect local load data on Monpura Island, located in Bhola, Bangladesh. Visible and design faults of the existing PV/diesel mini-grid have also been identified. Five alternative hybrid configurations have been considered as to evaluate the best optimum system. Two economic and one environmental criterion was used to size the system. Two experts specialized in energy systems evaluated the criteria and proposed the suitable system. Battery, wind and PV capital cost multipliers have been considered as to perform sensitivity analysis. According to techno-economic analysis and expert opinion, PV/biogas/wind has been found to be the most appropriate system among these configurations. The system has a cost of electricity (COE) of 0.691 (USD/kWh) and emits only 4.43 kg of CO2 per year. The net present cost of the proposed system is 18% lower than the existing microgrid, and the model has lower emissions due to high renewable penetration. It was also found that integrating wind can significantly reduce battery capacity in the mini-grid. The proposed system consumes 34% less batteries than the existing system. Implementing this optimum system can result in greater benefit to the local people.

The tension between power supply and demand is exacerbated for the increasing global refrigeration demand year by year. Therefore, refrigeration system driven by solar energy becomes one of the promising approaches to reduce or partially replace conventional refrigeration systems driven by power grid under the pressure of environmental protection and building energy conservation. Classified by operation mode, solar refrigeration is mainly composed of solar thermal refrigeration, solar photovoltaic refrigeration, and hybrid system consisting of solar thermal and photovoltaic energy. [1][2][3] Nowadays, the cost-effective advantage of photovoltaic (PV) refrigeration is prominent for the low PV module price. Therefore, PV refrigeration can attract many scholars for not only its considerable economic. More importantly, PV refrigeration reduces the dependence on power grid so as to effectively alleviate the contradiction between power supply and demand. [4][5][6] Besides, vapor compression refrigerator and air conditioning are important household appliances to improve people`s living standards, so most of the research work were focused on the PV refrigeration system.
