Abstract

Solar Power Plants (PLTS) are renewable-based electricity systems for areas not yet reached by the national grid. This study aims to design and test a small-scale PLTS system for lighting a farm house in Selayar Regency. The system consists of a 100 Wp solar panel, a PWM 10A charge controller, LiFePO4 batteries, and 30–40 W LED loads. The research method includes system design, assembly, and performance testing. The results show that the solar panel produced a voltage of 13.2–13.6 V, solar radiation intensity of 560–1235 W/m², and an average efficiency of 11.71%. The system meets daily energy needs of 1.260 Wh and provides lighting for 12 hours per night. This PLTS system proves effective as a clean energy solution for remote areas

Abstract

Penelitian ini membahas pemanfaatan panas buang knalpot sepeda motor menggunakan Thermoelectric Generator (TEG) sebagai sumber energi alternatif. Sebanyak 12 modul TEG tipe SP1848-27145 dipasang pada pipa knalpot dengan media plat aluminium dan heatsink. Pengujian dilakukan pada kondisi motor diam dan berjalan dengan variasi putaran mesin 2000 rpm, 2500 rpm, dan 3000 rpm. Tegangan tertinggi sebesar 7,59 Volt diperoleh pada kondisi motor diam tanpa beban pada putaran 3000 rpm, sedangkan daya tertinggi sebesar 3,78 Watt terjadi pada kondisi berbeban di 2500 rpm. Hasil menunjukkan bahwa panas buang knalpot dapat dikonversi menjadi energi listrik melalui TEG sebagai sumber energi tambahan. Namun, diperlukan optimalisasi sistem pendinginan dan jumlah modul untuk meningkatkan efisiensi dan kestabilan daya.

Abstract

This study aims to develop a design for a Public Electric Vehicle Charging Station of the fast-charging type for two-wheeled vehicles powered by a Solar Power Plant. The system is designed to support the clean energy transition and provide a sustainable charging solution. The Electric Vehicle Charging Station is assembled using a single solar panel with a capacity of 375 WP, a 12V 100Ah storage battery, an MPPT 60A controller, a 1200W 20A boost step-up converter, a 24V DC fan, a diode, and a battery capacity module. The test results show that the lithium-ion battery with an initial voltage of 48V and an initial charging current of 2.57A reached full charge (52V) within 1 hour and 30 minutes, while the SLA battery with an initial voltage of 52V and an initial charging current of 0.56A reached 52.8V in 3 hours and 10 minutes. The system demonstrated component stability, particularly in the boost converter, and operated effectively with a constant input power of 81.33W. However, the 12V 100Ah storage battery capacity was insufficient to charge more than one battery, indicating the need for a larger storage capacity.
