Indonesia is an archipelago which is one of the countries with the longest beaches in the world. One of the great potentials of the sea can be used to produce freshwater in coastal areas. One of the processes of converting seawater into freshwater vapor is the distillation process. The freshwater vapor condenses and turns into water. Distillation is carried out by evaporating seawater so that the freshwater is separated from the salt. In this research, the distillation process is assisted by a solar power plant with photovoltaic panels. The hardware design consists of a solar panel, solar charge controller, battery, inverter, pump, electric heater, temperature sensor, and level sensor. The solar panel uses a total of 1200Wp with a voltage of 12 V. The battery uses a 12V 100Ah battery and a 1000W electric heater. Meanwhile, the pump power is 48W. From the test results, it was found that in one hour, 1.3 liters of freshwater were obtained with a total capacity of 10 liters of water. The use of solar photovoltaic in a distillation system would be better if combined with direct solar energy heating methods.

印度尼西亚是一个群岛，是世界上海滩最长的国家之一。海洋的巨大潜力之一可用于在沿海地区生产淡水。将海水转化为淡水蒸汽的过程之一是蒸馏过程。淡水蒸气冷凝并变成水。蒸馏是通过蒸发海水来进行的，从而使淡水与盐分离。在这项研究中，蒸馏过程由带有光伏板的太阳能发电厂辅助。硬件设计由太阳能电池板、太阳能充电控制器、电池、逆变器、泵、电加热器、温度传感器和液位传感器组成。太阳能电池板共使用1200Wp，电压为12V。电池使用12V 100Ah电池和1000W电加热器。同时，泵浦功率为48W。从测试结果中发现，一小时内获得1.3升淡水，总容量为10升水。如果结合直接太阳能加热方法，在蒸馏系统中使用太阳能光伏会更好。
