Abstract: To replace fossil fuels that will run out at any time, it is important to improve the performance of solar energy which can be used to obtain electrical energy using photovoltaic systems. Photovoltaic system is a module that is used to absorb heat that is exposed to sunlight which is converted into electrical energy. The amount of potential sunlight that can be absorbed depends on the area of the cell and the absorption capacity of the solar cell to sunlight. The purpose of this research is the use of modules (solar panels) with a capacity of 100 wp that can absorb heat which is converted into electrical energy of 100 watts/hour which is later expected to be a substitute for conventional electricity which will be used for the refining process. The treatments were carried out by varying the drying time 0, 1, 2 and 3 days and the time for citronella oil refining operation for 2, 4 and 6 hours. In the Aceh area itself the sun shines at 10:00 WIB until 16:00 WIB. By using a solar cell that has a capacity of 100 wp for 6 hours a day when exposed to sunlight it can produce power of 600 watts/day. Therefore, this energy source is used for the oil refining process using a solar cell. 22 units of solar cells will be used, so in a day it can absorb 3,600 watts of electrical energy. The potential of electrical energy generated using solar cells can facilitate the process of refining essential oils. Testing of refined patchouli oil using the photovoltaic method for water content analysis. The best drying time is 3 days and the distillation time does not affect the water content produced, the value obtained is 11%. And the oil yield with a distillation time of 6 hours and a drying time of 3 days the value obtained was 2.47%. As for the analysis gas chromatography-mass spectrometry (GC-MS. The chemical compounds identified are patchouli alcohol namely 32.45% and 20.38% operating time for 2 hours and drying time for 3 days to produce patchouli oil products with good purity.
