Design Study of Solar Panel-Based Energy Trees as Clean Energy for Lighting Green Open Spaces

Abstract

Research aims to design and build an energy tree system as an eco-friendly lighting solution in the parking area of Campus 1 Swadaya Gunung Jati University, Cirebon City. This energy tree utilizes Solar Power Generation technology with a solar panel configuration resembling a tree, consisting of five polycrystalline solar panels with a total power of 110 WP (Watt Peak). The electrical energy generated from the solar panels is stored in a 12V/8Ah battery and then converted through an inverter into alternating current (AC). The method used in this research is an experimental method, which includes the stages of design, assembly, installation, and performance testing of the system. Testing was conducted over three consecutive days, from 09:00 to 16:00 WIB, aiming to evaluate the electrical output parameters, specifically the voltage and current, of solar panels. The system's maximum power output reached approximately 99.57W, with an average panel efficiency of 90.13% compared to the theoretical maximum capacity of 110WP
