Sistem PLTS off-grid dengan kapasitas output 3090 Wp dirancang untuk memenuhi kebutuhan listrik nelayan di Pulo Aceh. Pulo Aceh, sebuah kepulauan yang terletak di ujung barat Aceh, menghadapi tantangan pasokan listrik karena ketergantungan pada Pembangkit Listrik Tenaga Diesel (PLTD) yang sering mengalami gangguan operasional. Sebagian besar penduduknya adalah nelayan yang membutuhkan listrik untuk penerangan saat melaut dan pengisian baterai peralatan mereka. Penelitian ini menganalisis efisiensi sistem dengan fokus pada panel surya, MPPT, inverter, dan baterai, menggunakan beban pemanas 1500 W sebagai pengganti aki (Lead Acid 12V,70A). Hasil pengukuran menunjukkan nilai intensitas tertinggi tercatat sebesar 913,2 W/m², sedangkan nilai rata-rata harian berkisar antara 400-800 W/m² dalam rentang pukul 10.00-15.00 WIB. Hasil analisis pengukuran efisiensi panel yaitu 17,3-18,0% (sesuai standar monocrystalline 15-22%) dan Performance Ratio 85-89% (sesuai standar 80-90%). Analisis penelitian memperlihatkan PLTS 3090 Wp mampu mengisi hingga 21 aki per hari dengan pola 3 × 8 jam, lebih efisien dibandingkan penelitian sebelumnya yaitu PLTS 1440 Wp yang hanya mengisi 12 aki. Faktor intensitas matahari dan temperatur panel terbukti memengaruhi performa sistem. Dengan demikian, PLTS 3090 Wp layak digunakan untuk mendukung aktivitas nelayan Pulo Aceh sebagai solusi energi terbarukan yang stabil dan berkelanjutan.

An off-grid solar power system with an output capacity of 3090 Wp is designed to meet the electricity needs of fishermen in Pulo Aceh. Pulo Aceh, an archipelago located at the western tip of Aceh, faces electricity supply challenges due to its dependence on Diesel Power Plants (PLTD) which often experience operational disruptions. Most of the population are fishermen who need electricity for lighting while at sea and charging their equipment batteries. This study analyzes the system efficiency by focusing on solar panels, MPPT, inverter, and battery, using a 1500 W heating load as a replacement for batteries (Lead Acid 12V, 70A). The measurement results show that the highest intensity value was recorded at 913.2 W/m², while the daily average value ranged from 400-800 W/m² in the range of 10:00-15:00 WIB. The results of the panel efficiency measurement analysis are 17.3-18.0% (according to the monocrystalline standard 15-22%) and the Performance Ratio is 85-89% (according to the standard 80-90%). Research analysis shows that the 3090 Wp solar power plant can charge up to 21 batteries per day with a 3 x 8-hour cycle, more efficient than previous research, namely the 1440 Wp solar power plant, which only charged 12 batteries. Factors such as solar intensity and panel temperature have been shown to affect system performance. Therefore, the 3090 Wp solar power plant is suitable for use in supporting the activities of fishermen in Pulo Aceh as a stable and sustainable renewable energy solution.
