“…Therefore, care must be taken during the design process of SS, especially in the MSSs, to reduce the thermal energy losses by using prober insulations with lower thermal conductivity. 21 The diurnal exergy efficiencies of the CSS components, i.e., the basin liner, the glazier cover and the saline water, are 11.89%, 17.66% and 63.61%, respectively; these values are increased for the CuO nanofluid still and reach 13.40%, 23.18% and 80.83% for the basin liner, the glazier and the saline water, respectively. Moreover, these values are increased for the graphite nanofluid still and reach 12.32%, 23.76% and 93.35% for the basin liner, the glazier cover and the saline water, respectively, as shown in Fig.5-b.…”

“…Due to low yield of the SSs, many investigators introduced several scrupulous designs to enhance the output by enhance the evaporation rate of water. Researchers suggested different designs to improve the SSs' performance, such as double slope [3], stepped SS [4,5], SS with phase change materials (PCMs) [6][7][8][9] wick SS [ 10 -12 ] , hybrid SS [13][14][15], stepped SS with continual water circulation [ 3 ] , wind speed [16], SS with storage materials [17,18], SS with nanoparticles [19], SS with PV/T [20][21][22] , and SS with vertical ripple surface [23].…”

“…The same method has been used by several authors in similar studies dealing with exergy analysis of solar stills with PCMs as thermal storage [62][63][64]. This process of exergy of a system is irreversible due to the generated entropy and the exergy can only be preserved if the process is reversed.…”

The application of thermal storage materials in solar systems involves materials that utilize sensible heat energy, thermo-chemical reactions or phase change materials, such as hydrated salts, fatty acids paraffin and non-paraffin like glycerol. This article reviews the various exergy approaches that were applied for several solar systems including hybrid solar water heating, solar still, solar space heating, solar dryers/heaters and solar cooking systems. In fact, exergy balance was applied for the different components of the studied system with a particular attention given to the determination of the exergy efficiency and the calculation of the exergy during charging and discharging periods. The influence of the system configuration and heat transfer fluid was also emphasized. This review shows that not always the second law of thermodynamics was applied appropriately during modeling, such as how to consider heat charging and discharging periods of the tested phase change material. Accordingly, the possibility of providing with inappropriate or not complete results, was pointed.

Present communication is an attempt to explore the best PV technology suitable for PVT solar drying system through environmental and economic feasibility. Experimental setup for one of the PV technology (c‐Si) has been taken for experimental validation with theoretical model. Further, the environmental feasibility and environ economic evaluation for drying system having roof with various PV namely, c‐Si, p‐Si or m‐Si, a‐Si, CdTe, and CIGS have been evaluated through energy matrices (EPBT, EPF, and LCCE), CO2 emission, net CO2 mitigation and carbon credit earned which is based on energy and exergy output of the system on yearly basis. The economic analysis has been carried out with experimental data taken on c‐Si PVT drying system by considering grapes as a crop. Cogeneration efficiency has been calculated for different PV technologies and found to be highest for c‐Si PV technology that is, 61.71%, 77.98%, and 12.25% based on energy (electrical and thermal) gain, equivalent (overall) energy gain, and exergy gain, respectively. LCCE on energy basis reveals that for the five‐year system life, c‐Si and CIGS have equal efficiency but after five years, c‐Si is best. Cogeneration efficiency of system on the basis of energy (electrical + thermal) gain, equivalent (overall) energy gain and overall exergy gain found to be maximum with c‐Si PV technology that is, 61.71%, 77.98%, and 12.25%, respectively.
