One of the factors for the long endurance of high altitude long endurance (HALE) of an unmanned aerial vehicle (UAV) that belong to Institut Teknologi Bandung, Indonesia or called as HALE UAV ITB is the design of battery and solar panel. This paper discusses the method to calculate battery and solar panel requirements for HALE UAV ITB to fly for more than 24 hours at 20.000 feet. Several designs, configuration, and type of solar panels are analysed to fulfil HALE UAV ITB requirements. The variable compared is solar panel area, weight, and types. As a result, the use of Monocrystalline Silicone solar cell was found to be much more efficient than Polycrystalline Silicon, CIGS Thin Film, and Amorphous Silicon Thin Film with power generated per area of 224 Watt/m2 and power per weight of 436 Watt/kg. The minimum area required for a Monocrystalline Silicone type solar cell to generate power is 5.94 m2 with a total cell weight of 5.31 kg.

印度尼西亚万隆技术研究所（Institut Teknologi Bandung，Institut Teknologi Bandung）或称为HALE UAV ITB的无人机（UAV）的高空长航时（HALE）长航时的因素之一是电池和太阳能电池板的设计。本文讨论了计算 HALE UAV ITB 在 20.000 英尺高空飞行超过 24 小时的电池和太阳能电池板要求的方法。分析了几种太阳能电池板的设计、配置和类型，以满足 HALE UAV ITB 要求。比较的变量是太阳能电池板面积、重量和类型。结果，发现使用单晶硅太阳能电池比多晶硅、CIGS 薄膜和非晶硅薄膜的效率高得多，单位面积发电量为 224 瓦/平方米，单位重量功率为 436 瓦/公斤.
