Solar energy is considered the most influential source for various sustainable applications and its utilization can effectively convert brackish water into freshwater. The present work explores a novel method of augmenting the water productivity of the desalination unit using sea-water as the feed water through integrating a parabolic trough collector (to preheat the water supplied to the still basin) and activated carbon pellet (a highly porous energy storage material) to improve the rates of evaporation and water production. Experimental results revealed that the full-day water yield was augmented by 50.21% for the modified desalination unit, as compared to the conventional unit. 24-Hours water yield of modified solar still was increased by 85.2% compared to the conventional unit, owing to the synergetic effect of the parabolic trough and porous carbon. However, the integration of the parabolic trough collector significantly reduced the energy and exergy efficiency of the modified unit. The economic analysis estimated that the cost of the produced clean water was 0.010 US $ per liter for the modified unit, with a payback period of 66 days. Moreover, it was found that the modified desalination unit configuration can reduce CO₂ emissions by 18.74 tons during its lifespan.

太阳能被认为是各种可持续应用最具影响力的来源，其利用可以有效地将咸水转化为淡水。目前的工作探索了一种通过集成抛物线槽式收集器（预热供应到静水池的水）和活性炭颗粒（一种高度多孔的能量）来提高使用海水作为给水的海水淡化装置的水生产率的新方法。储存材料）以提高蒸发率和产水率。实验结果表明，与传统装置相比，改进型海水淡化装置的全天产水量增加了 50.21%。改造后的太阳能蒸馏器24小时出水量比传统装置提高85.2%，由于抛物线槽和多孔碳的协同作用。然而，抛物槽收集器的集成显着降低了改进单元的能量和火用效率。经经济分析估算，改造后的机组每升生产净水成本为0.010美元，投资回收期为66天。此外，发现改进的海水淡化装置配置可以减少 CO₂在其使用寿命期间排放量减少 18.74 吨。
