Abstract

Salah satu solusi utama untuk memenuhi kebutuhan listrik adalah penggunaan panel surya (PV), yang menjadi pilihan dalam transisi menuju energi bersih dan berkelanjutan. Namun, efisiensi panel surya sering menurun akibat peningkatan temperatur yang disebabkan oleh paparan sinar matahari, sehingga mengurangi konversi energi hingga 0,4% per derajat celcius. Penelitian ini bertujuan untuk menganalisis pengaruh sistem pendinginan berbasis fluida air dan media berpori alami, yaitu serat pisang dan serat kelapa sawit, terhadap distribusi temperatur dan efektivitas pendinginan panel surya pada variasi kecepatan aliran fluida. Hasil simulasi menunjukkan bahwa sistem pendinginan dengan air dan material berpori secara signifikan dapat menurunkan temperatur permukaan panel surya dibandingkan dengan panel tanpa sistem pendingin. Penerapan sistem pendinginan berbasis air menurunkan temperatur menjadi 49,83°C, sedangkan penurunan lebih besar terjadi saat menggunakan material berpori, dengan serat pisang mencatatkan temperatur sebesar 42,52°C dan serat kelapa sawit menunjukkan nilai terendah yaitu 42,11°C. Secara umum, efektivitas pendinginan meningkat seiring bertambahnya kecepatan fluida, dengan rata-rata peningkatan efektivitas berkisar antara 8% hingga 15% di setiap kenaikan kecepatan. Serat kelapa sawit menunjukkan efektivitas pendinginan tertinggi dibandingkan air dan serat pisang, sehingga dapat menjadi alternatif yang lebih baik dalam menurunkan dan menstabilkan temperatur panel surya.

One of the main solutions to meet electricity demand is the use of solar panels (PV), which has become a preferred option in the transition toward clean and sustainable energy. However, the efficiency of solar panels often decreases due to temperature increases caused by sunlight exposure, reducing energy conversion by up to 0,4% per degree Celsius. This study aims to analyze the effect of a cooling system based on water fluid and natural porous media, namely banana fiber and oil palm fiber, on the temperature distribution and cooling effectiveness of solar panels at varying fluid flow rates. The simulation results show that cooling systems using water and porous materials can significantly reduce the surface temperature of solar panels compared to those without cooling systems. The implementation of a water-based cooling system lowers the temperature to 49,83°C, while a greater reduction occurs when using porous materials, with banana fiber recording a temperature of 42,52°C, and oil palm fiber showing the lowest value at 42,11°C. In general, cooling effectiveness increases with higher fluid velocity, with an average improvement ranging from 8% to 15% at each velocity increment. Oil palm fiber demonstrates the highest cooling effectiveness compared to water and banana fiber, making it a better alternative for lowering and stabilizing solar panel temperatures.
