Functionalization of a 110 Wp Photovoltaic System for Computer Room Power Supply at SMK Muhammadiyah 2 Turi Sleman

Abstract

Sekolah Menengah Kejuruan Muhammadiyah 2 Turi Sleman has a photovoltaic system that powers the computer room. However, since 2022, the system has not been working correctly. This paper aims to restore the photovoltaic system’s functionality. The activities include checking the condition of the system’s components and taking corrective actions. During the inspection, it was found that the solar module was not installed outdoors, and the battery’s performance had decreased, showing a voltage of only 11.95 V. The solar module had been installed outdoors correctly. Performance tests revealed that the system can produce electrical energy, with the solar module generating an average open circuit voltage of 23.32 V in sunny weather. The battery repair resulted in an average voltage of 12.23 V. The photovoltaic system now functions as a power supply for the computer room.
