Abstract

The increasing demand for clean electrical energy in Indonesia highlights the need to optimize solar power generation technologies. Bifacial photovoltaic (PV) panels offer higher energy yield by utilizing solar radiation from both front and rear sides; however, their performance is strongly influenced by reflective properties of the surface beneath the panel. This study aims to analyze the effect of reflective surface variations with different albedo values on the power output and efficiency of bifacial solar panels under tropical rainy season conditions. An experimental method was employed using three identical bifacial PV modules (545 Wp) installed above asphalt, paving block, and white-painted surfaces. The modules were installed with a tilt angle of 8°, an azimuth angle of 0° (facing north), and a height of 60 cm above the surface. Measurements of solar irradiance, voltage, and current were conducted at irradiance levels ranging from 203 to 1001 W/m². Data were collected three days with same conditions and parameter in November 2024 during the period time from 09:00 to 15:00. The results show that to enhance rear-side irradiance, as indicated by the increase in output power observed in this study, leading to increased output power and efficiency. The white-painted surface produced the highest performance, achieving an average power increase of approximately 9.6% and a maximum efficiency of 16.3% compared to asphalt and paving block surfaces. These findings indicate that high-albedo surfaces are an effective solution for improving bifacial solar panel performance, particularly in wet tropical climates such as Bandung, Indonesia.

Abstract

Pengabdian kepada masyarakat di Sekolah Alam Tasdiquul Insan, Desa Curuggrendeng, Subang, Jawa Barat, dilakukan melalui pemanfaatan Pembangkit Listrik Tenaga Surya (PLTS) hybrid sebagai alternatif sumber listrik utama guna mendukung kegiatan belajar mengajar. Program ini dilatarbelakangi oleh kebutuhan akan ketersediaan energi listrik yang stabil dan berkelanjutan di lingkungan sekolah. Metode yang digunakan adalah penerapan teknologi tepat guna melalui tahapan persiapan, perancangan sistem, pemasangan alat, pengujian, pelatihan, serta dokumentasi kegiatan. Sistem PLTS yang diterapkan menggunakan panel surya sebagai sumber utama energi listrik yang dikonversi melalui inverter hybrid dari arus DC ke AC untuk memenuhi kebutuhan beban utama sekolah, seperti lampu, proyektor, dan laptop. Energi listrik yang dihasilkan secara berlebih akan disimpan dalam baterai untuk digunakan pada malam hari maupun saat kondisi cuaca mendung atau hujan. Hasil pengujian menunjukkan bahwa inverter berkapasitas 1,2 kW mampu menghasilkan daya sebesar 834,17 W atau sekitar 92,7% dari kapasitas nominal dengan faktor daya sebesar 0,98, yang menunjukkan kinerja sistem yang efisien dan stabil. Pemanfaatan PLTS ini menjadikan sekolah lebih mandiri dalam penyediaan listrik sekaligus sebagai media edukasi energi terbarukan yang ramah lingkungan dan berkelanjutan bagi peserta didik.
