“…This system can generate 100 litres of fresh water daily with an SEC of 3.6 kWh/m 3 , using 2 m 2 panels in different weather conditions. Xinxin et al [102] designed three solar still systems with different glass angles integrated with a concentrated parabolic PVT system, as depicted in Figure 13c. The researchers found that higher solar irradiation increases freshwater generation, electrical efficiency, and thermal efficacy.…”

The growing demands of modern life, industrialization, and technological progress have significantly increased energy requirements. However, this heightened need for energy has raised concerns about its impact on the environment and the rising costs associated with it. Therefore, the engineering sector is actively seeking sustainable and cost-effective energy solutions. Among the promising innovations in solving the problem is the photovoltaic thermal system (PVT), which aims to capture electrical and thermal energy from solar radiation. Despite its potential, the application of PVT systems is currently limited due to the unpredictable nature of solar energy and the absence of efficient thermal energy storage capabilities. To address these challenges, researchers have explored the use of phase change materials and nano-improved phase change materials (NEPCMs) to optimize energy extraction from solar systems. By incorporating these materials, the PVT system can maximize energy utilization. This article provides a comprehensive overview of the potential applications of PVT techniques in both industrial and building settings. It also offers a detailed assessment of their commercial and environmental aspects. The research findings highlight several advantages of PVT systems, including reduced electricity consumption, efficient utilization of cooling and heating loads during off-peak periods, improved temperature stability, and enhanced thermal comfort. Furthermore, the integration of NEPCMs in PVT systems has demonstrated superior thermal performance, enabling 8.3% more heat energy storage during charging and 25.1% more heat energy release during discharging. Additionally, the implementation of solar-assisted combined heating and power systems showed the potential to prevent the emission of 911 tons of CO2 per year compared to conventional PV systems. These systems offer a promising pathway towards mitigating environmental impacts while meeting energy demands. Overall, this review article serves as a valuable resource for fellow researchers by providing detailed insights into the viability of PVT systems for various applications in the industrial and building sectors.

“…The yield of pure water is also increased by concentrating the solar irradiation level. [ 30 ] Ashok Kumar Singh and Samsher performed techno–environ–economic–energy and exergy analysis and investigated the solar desalination system with an evacuated annulus tube along with the modified parabolic concentrator. 5.4 kg m −2 of daily yield was achieved at the production cost 0.005$ L −1 .…”

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.

“…At the same time, they can also provide a certain energy output when applied to non-energy buildings (Parupudi, et al, 2020). When LCPV systems are used in the field of seawater desalination, studies have shown that the total output of fresh water will increase significantly during the day, and the solar radiation intensity can effectively improve the thermal efficiency of the system (Xinxin, et al, 2019). Through software simulation, it can be known that considering the factors of incident angle and concentration ratio, different degrees of deformation of the compound parabolic concentrator (CPC) will have a certain impact on the CPC concentration (Xu, et al, 2018).…”

Photovoltaic panels can directly convert solar energy into electricity, but temperature will have a certain impact on the efficiency of photovoltaic cells. Especially under the condition of nonuniform energy flow density of high-power concentration, it is of great significance to maintain the temperature uniformity of cells. Therefore, based on the radiation under nonuniform heat flux density, four heat exchangers were proposed: single-channel serpentine flow, multi-channel flat plate, full jet, and single-jet nozzle. Taking into account the uniformity of the cell temperature, the single-jet nozzle and single-channel serpentine flow can better maintain the uniformity of the temperature field compared with other heat exchangers. Especially under high-concentration energy flow density, considering the quality of heat and electricity, the performance of the four-jet nozzles is the best from the perspective of exergy efficiency. Under the condition of four-jet nozzles, the electrical efficiency and thermal efficiency of the cell can be maintained at about 29 and 62.5%, respectively, and the exergy efficiency of the system can reach 31%.
