Abstract

Panel surya menghasilkan listrik bersih, tetapi efisiensinya dapat dipengaruhi oleh faktor-faktor seperti suhu. Penelitian ini bertujuan untuk menyelidiki bagaimana menambahkan sistem pendingin ke panel surya memengaruhi output dayanya dan cara perpindahan panas. Penelitian dilakukan dengan menggunakan metode eksperimental untuk memperoleh data intensitas radiasi matahari, tegangan, arus, nilai efisiensi konversi dari panel surya, Penelitian ini menggunakan empat panel surya Monokristalin 100Wp NMS100W dengan variasi (a) tanpa kipas angin; (b) 3 kipas berukuran 60x60mm; (c) 3 kipas berukuran 120x120mm; dan (d) 6 kipas berukuran 60x60mm dengan interval waktu masing-masing satu jam pada pukul 10:00, 11:00, 12:00, 13:00, dan 14:00 WIB. Berdasarkan hasil penelitian, nilai output daya dalam variasi (b), (c), dan (d) menghasilkan rata-rata 69,21 W, 70,44 W, dan 70,14 W. Nilai efisiensi konversi dalam variasi (a), (b), (c), dan (d) menghasilkan rata-rata 15,29%, 16,69%, 16,93%, dan 16,87%. Suhu panel surya dapat dijaga secara efisien dalam variasi (a), (b), (c), dan (d), yaitu 51,40°C, 42,90°C, 42,09°C, dan 42,73°C. Nilai efisiensi dalam variasi (a), (b), (c), dan (d) menghasilkan rata-rata 15,29%, 16,69%, 16,93%, dan 16,87%. Nilai energi total (Wgenerated) dalam variasi (a), (b), (c), dan (d) menghasilkan rata-rata 318,74 Wh, 346,07 Wh, 352,18 Wh, dan 350,69 Wh. Konsumsi energi listrik yang dibutuhkan dalam variasi (b), (c), dan (d) adalah 162 Wh, 180 Wh, dan 324 Wh. Nilai energi bersih (Wnett) dalam variasi (a), (b), (c), dan (d) menghasilkan rata-rata 318,74 Wh, 184,07 Wh, 172,18 Wh, dan 26,69 Wh. Konfigurasi dengan 3 kipas 12x12 mendapat manfaat dari luas permukaan konveksi paksa yang lebih tinggi dan panjang karakteristik yang berkurang di area yang mengalami konveksi bebas, yang secara kolektif meningkatkan koefisien konveksi secara keseluruhan. Meski begitu, penggunaan kipas mempengaruhi daya keluaran, efisiensi konversi, penurunan suhu, efisiensi, dan penyerapan energi listrik pada panel fotovoltaik.

Solar panels generate clean electricity, but their efficiency can be impacted by factors like temperature. This study aims to investigate how adding a cooling system to solar panels affects their power output and the way heat transfers. The research was conducted using an experimental method to obtain data on solar radiation intensity, voltage, current, conversion efficiency values from solar panels, This research uses four NMS100W Monocrystalline 100Wp solar panels with variations of (a) without fans; (b) 3 fans of 60x60mm size; (c) 3 fans of 120x120mm size; and (d) 6 fans of 60x60mm size with each one-hour time interval at 10:00, 11:00, 12:00, 13:00, and 14:00 WIB. Based on the research results, the power output value in variations (b), (c), and (d) produces an average of 69.21 W, 70.44 W, and 70.14 W. The conversion efficiency value in variations (a), (b), (c), and (d) produces an average of 15.29%, 16.69%, 16.93%, and 16.87%. The temperature of the solar panel can be maintained efficiently in variations (a), (b), (c), and (d), namely 51.40°C, 42.90°C, 42.09°C, and 42.73°C. The efficiency values in variations (a), (b), (c), and (d) resulted in an average of 15.29%, 16.69%, 16.93%, and 16.87%. The total energy value (Wgenerated) in variations (a), (b), (c), and (d) resulted in an average of 318.74 Wh, 346.07 Wh, 352.18 Wh, and 350.69 Wh. The electrical energy consumption required in variations (b), (c), and (d) are 162 Wh, 180 Wh, and 324 Wh. The net energy value (Wnett) in variations (a), (b), (c), and (d) resulted in an average of 318.74 Wh, 184.07 Wh, 172.18 Wh, and 26.69 Wh. The configuration with 3 12x12 fans benefits from a higher forced convection surface area and a reduced characteristic length in areas experiencing free convection, which collectively increases the overall convection coefficient. Even so, the use of fans affects the output power, conversion efficiency, temperature drop, efficiency, and absorption of electrical energy in photovoltaic panels.
