Rancang Bangun Alat Pengukur Panel Surya Monocrystalline Dan Polycrystalline Dengan Metode pulse Repair Battery Charger

Abstract

Salah satu tantangan global, termasuk di Indonesia, adalah masalah energi. Indonesia memiliki potensi energi surya sebesar 4,8 kWh/m²/hari, menjadikannya pilihan tepat untuk energi terbarukan, terutama di rumah tangga. Panel surya tipe monocrystalline dan polycrystalline umumnya digunakan, namun kinerjanya bergantung pada produsen dan kondisi pengujian. Pengujian standar dilakukan di bawah Standard Test Conditions (STC) berdasarkan IEC 61215, namun kondisi ini jarang terjadi dalam praktik sehari-hari. Efisiensi aktual panel dipengaruhi oleh faktor seperti lokasi, suhu, dan intensitas radiasi, yang menyebabkan perbedaan antara kinerja lapangan dan spesifikasi pabrikan. Penelitian ini bertujuan mengukur dan membandingkan kinerja kedua tipe panel menggunakan alat Pulse Repair Battery Charger. Metode eksperimental ini menghasilkan data yang dianalisis dalam tabel. Hasilnya menunjukkan bahwa panel monocrystalline dan polycrystalline memiliki kinerja suboptimal dengan efisiensi masing-masing 7,19% dan 7,29%. Nilai Fill Factor sebesar 0,2 menunjukkan masalah kualitas material. Untuk meningkatkan kinerja, diperlukan evaluasi lebih lanjut terhadap resistansi internal serta optimasi desain dan pemeliharaan pane.l One of the global challenges, including in Indonesia, is the issue of energy. Indonesia has a solar energy potential of 4.8 kWh/m²/day, making it an ideal choice for renewable energy, particularly in households. Monocrystalline and polycrystalline solar panels are commonly used; however, their performance depends on the manufacturer and testing conditions. Standard testing is conducted under Standard Test Conditions (STC) based on IEC 61215, though these conditions rarely occur in real-world operations. Actual panel efficiency is influenced by factors such as location, temperature, and radiation intensity, leading to discrepancies between field performance and manufacturer specifications. This study aims to measure and compare the performance of both panel types using a Pulse Repair Battery Charger. The experimental method produced data that was analyzed in tables. The results showed that both monocrystalline and polycrystalline panels have suboptimal performance with efficiencies of 7.19% and 7.29%, respectively. A Fill Factor value of 0.2 indicates material quality issues. To improve performance, further evaluation of internal resistance and optimization of panel design and maintenance is required.
