Solar water desalination is the future alternative to overcome both pollution and water shortage issues. This study describes the effect of a low-cost cotton wick material on the performance of tubular solar still integrated with a parabolic concentrator solar tracking system. Outdoor experimental work was conducted in the real field under July climatic conditions of Ha'il city (995 m above sea level), Saudi Arabia. Results of the tubular solar still with and without the wick were compared to evaluate the achieved improvement of the developed device. Comparative analysis shows a higher performance for the wicked device with a significantly lower freshwater production cost. The use of the black cotton wick increased the device productivity and efficiency by 29.11% and 24.45%, respectively, and lowered water desalination production cost by 40.21%. The device with the wick was able to produce 5.1 L/m²day of water desalination with the 40.21% lower cost compared with that of the device without the wick. This productivity can satisfy the basic needs of one person during a day in small and isolated communities.

太阳能海水淡化是解决污染和水资源短缺问题的未来替代方案。本研究描述了低成本棉芯材料对仍与抛物面聚光太阳能跟踪系统集成的管状太阳能性能的影响。室外试验工作在沙特阿拉伯哈伊勒市（海拔995米）7月气候条件下在实场进行。比较了有和没有灯芯的管状太阳能蒸馏器的结果，以评估所开发设备所取得的改进。比较分析表明，具有显着降低淡水生产成本的 wicked 装置具有更高的性能。黑棉芯的使用分别使装置生产率和效率分别提高了 29.11% 和 24.45%，并将海水淡化生产成本降低了 40%。21%。带有灯芯的装置能够产生 5.1 L/m^脱盐2天，成本比不带灯芯的装置低40.21%。这种生产力可以满足一个人在小而孤立的社区中一天的基本需求。
