Abstract

Sebagaimana energi fosil telah mulai berkurang, maka sangat penting untuk memanfaatkan energi alternatif seperti energi surya. Suatu peralatan yang dapat digunakan untuk menangkap dan mengubah energi surya adalah kolektor surya. Dua kolektor surya identik digunakan dalam penelitian ini ditempatkan menghadap ke Utara dengan sudut kemiringan 15 °. Dimensi kolektor adalah 0,8 m x 1 m x 0,05 m. Salah satu kolektor yang terdiri dari 5 pipa paralel dan lainnya yang terdiri dari  7 pipa paralel. Air yang digunakan dalam percobaan ini  mengalir secara alami karena gaya gravitasi dari tangki yang lebih tinggi dan diatur  dengan katup dipasang pada sisi keluaran kolektor. Laju aliran air yang digunakan adalah 200, 250 dan 300 cc / menit dan diukur dengan menggunakan gelas ukur  dan stop watch. Hasil penelitian menunjukkan bahwa energi yang masuk ke kolektor, energi yang diserap oleh absorber dan air, naik dengan meningkatnya  waktu observasi dan mencapai nilai puncak pada sekitar pukul 02:30 Wita. Setelah itu, menurun. Pengaruh jumlah pipa adalah tidak signifikan.  Kata kunci: kolektor surya, absorber batu granit, performa kolektor

Abstract

As the fossil energy has been getting depletion, it is important to utilize alternative energies such as solar energy. An equipment that can be used for capturing and converting solar energy is solar collector. Two identical collectors used in this study were placed facing to the North with an inclination angle of 15°. The collector dimension was 0.8 m x 1 m x 0.05 m. One collector contained 5 parallel pipes and the other contained 7 parallel pipes.  The water used in the test was flowed naturally due to the gravity force from a higher tank and was adjusted using a valve fitted at the end of the collector. The water flow rates employed were 200, 250 and 300 cc/minutes and  measured using a volume meter and a stop watch. The results showed that the energy coming into the collector, energy absorbed by the absorber and water, increased with an increase in the observation time and reached the peak value at about  2.30 pm. After that, they decreased. The effect of the pipe number is significant and the performance of the collector containing 7 pipes is better than that containing 5 pipes.
