Abstract This paper presented for the first time the performance of two identical active solar still at the summit of the Mount Tochal (35.6892°N, 51.3890°E) and Tehran (35.8842°N, 51.4199°E) at the height of 13,005 and 3871 ft respectively. The proposed system is a single-slope and single-basin solar still equipped with thermoelectric modules (TEM) as heater powered by photovoltaic (PV) panels. A Series of experiments in three consecutive days from 28.07.2018 to 30.7.2018 on the mountain and Tehran were performed simultaneously. The highest hourly yield at the summit and Tehran reach to 505 ml/h and 360 ml/h respectively. Results showed that the instantaneous efficiency on the mountain hits the highest point to about 66.5% which shows an improvement about 27.8% in comparison with Tehran. Also, total productivity at the summit is 42.5% higher than Tehran. Findings revealed that the overall heat transfer coefficient at the summit is slightly greater rather than Tehran. Temperature difference between water and glass at the summit significantly is higher than Tehran which leads to higher rate of condensation. Moreover, temperature of PV at summit is colder than Tehran that results in better performance of panel.

在海拔 13,000 英尺以上的山顶上对光伏驱动的主动式太阳能静水净化进行实验研究：一项比较研究

摘要 本文首次介绍了两个完全相同的活动太阳静止器在 Tochal 山顶（35.6892°N, 51.3890°E）和德黑兰（35.8842°N, 51.4199°E）海拔 13,005 和 3871英尺分别。所提议的系统是配备有热电模块 (TEM) 作为由光伏 (PV) 面板供电的加热器的单坡和单盆太阳能蒸馏器。从 2018 年 7 月 28 日到 2018 年 7 月 30 日，连续三天在山上和德黑兰同时进行了一系列实验。山顶和德黑兰的最高每小时产量分别达到 505 毫升/小时和 360 毫升/小时。结果表明，山上的瞬时效率达到最高点，达到约 66.5%，与德黑兰相比提高了约 27.8%。此外，山顶的总生产力为 42。比德黑兰高 5%。调查结果显示，山顶的整体传热系数略大于德黑兰。山顶的水和玻璃之间的温差明显高于德黑兰，导致冷凝率更高。此外，山顶光伏的温度比德黑兰低，这导致面板性能更好。
