Abstract

Pembangkit Listrik Tenaga Surya (PLTS) merupakan sumber Energi Baru Terbarukan (EBT) yang memiliki potensi besar di Indonesia karena ketersediaan radiasi matahari yang melimpah sepanjang tahun. Kinerja sistem PLTS dipengaruhi oleh berbagai faktor seperti sudut kemiringan panel, kondisi pemasangan, dan shading parsial. Penelitian ini bertujuan menganalisis pengaruh shading parsial 50% dan variasi sudut kemiringan panel (10°, 20°, 30°) terhadap kinerja PLTS 40 Wp pada konfigurasi Rooftop dan Ground-mounted, mengevaluasi produksi energi harian berdasarkan Peak Sun Hour (PSH), serta memvalidasi hasil dengan simulasi PVsyst menggunakan lima variabel bebas (sudut, shading, konfigurasi, intensitas radiasi, dan temperatur) yang diuji melalui regresi linear berganda. Penelitian dilaksanakan di Gedung FT UKI Jakarta Timur pada Maret–Mei 2026. Hasil menunjukkan konfigurasi Ground-mounted 10° menghasilkan performa terbaik dengan energi harian tanpa shading 94,379 Wh dan pencapaian PSH 49,16%, sedangkan pada kondisi kombinasi variasi sudut kemiringan dengan shading parsial 50% turun menjadi 81,432 Wh dan pencapaian PSH 42,41%. Analisis regresi menunjukkan sudut kemiringan sebagai prediktor paling dominan terhadap daya keluaran (Beta = -0,668, p < 0,001). Simulasi PVsyst menunjukkan tren yang konsisten dengan pengukuran lapangan meskipun nilainya lebih tinggi. "/" Solar Power Plants (SPPs) are one of the Renewable Energy (RE) sources with significant potential in Indonesia due to the abundant availability of solar radiation throughout the year. The performance of photovoltaic (PV) systems is influenced by various factors, including panel tilt angle, installation configuration, and partial shading. This study aims to analyze the effect of 50% partial shading and variations in panel tilt angles (10°, 20°, and 30°) on the performance of a 40 Wp photovoltaic system under Rooftop and Ground-mounted configurations, evaluate daily energy production based on Peak Sun Hours (PSH), and validate the results using PVsyst simulation with five independent variables (tilt angle, shading, installation configuration, solar irradiance, and temperature) analyzed through multiple linear regression. The research was conducted at the Faculty of Engineering Building, the Universitas Kristen Indonesia, East Jakarta, from March to May 2026. The results indicate that the Ground-mounted configuration with a 10° tilt angle achieved the best performance, producing 94.379 Wh of daily energy under unshaded conditions with a PSH achievement of 49.16%. Under the combined condition of varying tilt angles and 50% partial shading, the daily energy production decreased to 81.432 Wh, with a PSH achievement of 42.41%. Multiple linear regression analysis identified the panel tilt angle as the most dominant predictor of output power (Beta = −0.668, p < 0.001). The PVsyst simulation showed a trend consistent with the field measurements, although the simulated values were higher than the experimental results.
