Abstract
Peningkatan kebutuhan energi global dan ketergantungan pada bahan bakar fosil telah mendorong urgensi pengembangan Energi Baru Terbarukan (EBT) untuk mendukung transisi menuju sistem energi yang lebih berkelanjutan. Salah satu sumber energi terbarukan yang menjanjikan adalah energi surya karena potensi paparan sinar matahari di Indonesia mencapai ±12 jam per hari. Namun, panel surya hanya mampu mengonversi 15-20% energi matahari menjadi listrik. Sisa energi matahari yang diserap akan menyebabkan peningkatan suhu panel surya dan akan menurunkan efisiensi hingga 0,65% per kenaikan suhu 1°C. Maka dari itu, perlu dilakukan penelitian yang bertujuan untuk meningkatkan efisiensi konversi panel surya monocrystalline melalui penerapan sistem pendingin berbasis Nano Enhanced Phase Change Material (NePCM). Material yang digunakan adalah campuran paraffin wax dengan nanopartikel Aluminium Oksida (Al2O3). Metode eksperimen dilakukan dengan tiga konfigurasi utama, yakni panel surya tanpa sistem pendingin, dengan pendingin berbasis PCM murni, dan dengan pendingin berbasis NePCM menggunakan variasi kadar nanopartikel sebesar 1%, 2%, dan 3%. Eksperimen dilakukan di Atap Gedung Departemen Teknik Mesin ITS, Surabaya, dengan melakukan pengambilan data temperatur atas, temperatur bawah panel surya, dan temperatur cover PCM, intensitas radiasi matahari, serta arus dan tegangan keluaran menggunakan alat ukur dan rangkaian sensor yang terhubung dengan data logger. Data yang diperoleh kemudian diolah untuk menganalisis pengaruh PCM dan NePCM terhadap performa panel surya. Hasil pengujian menunjukkan bahwa PCM dan NePCM mampu menurunkan temperatur panel surya. Variasi NePCM 3% memberikan hasil terbaik dengan rata-rata temperatur sebesar 47,25 °C. Penambahan nanopartikel juga meningkatkan daya luaran harian, di mana NePCM 3% menghasilkan daya luaran tertinggi sebesar 72,18 W. Efisiensi konversi energi tertinggi juga dicapai oleh NePCM 3% sebesar 22,69%. Secara keseluruhan, peningkatan kadar nanopartikel dalam PCM terbukti mampu meningkatkan kinerja panel surya.

The increasing global energy demand and dependence on fossil fuels have driven the urgency for the development of Renewable Energy (RE) to support the transition toward a more sustainable energy system. One of the promising renewable energy sources is solar energy, as Indonesia experiences sunlight exposure of approximately 12 hours per day. However, solar panels can only convert 15-20% of solar energy into electricity. The remaining absorbed solar energy causes an increase in the solar panel temperature, reducing efficiency by 0.65% for every 1°C rise in temperature. Therefore, research is needed to enhance the conversion efficiency of monocrystalline solar panels through the application of a cooling system based on Nano Enhanced Phase Change Material (NePCM). The material used is a mixture of paraffin wax with Aluminum Oxide (Al2O3) nanoparticles. The experimental method involved three main configurations: solar panels without a cooling system, panels with a pure PCM-based cooling system, and panels with a NePCM-based cooling system using nanoparticle concentrations of 1%, 2%, and 3%. The experiment was conducted on the rooftop of the Department of Mechanical Engineering at ITS, Surabaya, by collecting data on panel and PCM temperature, solar radiation intensity, current output, and voltage output, recorded using measurement instruments and a sensor system connected to a data logger. The results show that the use of PCM and NePCM contributes to lowering the panel temperatures. The 3% NePCM variation recorded the lowest average temperature of 47,25 °C. It also yielded the highest average daily power output of 72.18 W. The highest conversion efficiency, 22.69%, was also obtained from the 3% NePCM variation. Overall, increasing the concentration of nanoparticles in the PCM contributes to enhances the performance of solar panels.
