Abstract

Salah satu peralatan yang dapat memanfaatkan energi matahari adalah kolektor surya hybrid PV/T. Kolektor jenis ini merupakan gabungan antara panel surya dengan kolektor termal sehingga dapat menghasilkan energi listrik dan energi termal dalam waktu bersamaan. Namun jika terjadi peningkatan temperatur pada permukaan panel PV maka akan terjadi penurunan unjuk kerja dari panel PV tersebut.  Tujuan dari penelitian ini adalah untuk mengetahui sekaligus membandingkan unjuk kerja kolektor surya hybrid PV/T secara termal dan pressure drop berdasarkan perbedaan bentuk penampang pipa absorber. Penampang pipa yang dibandingkan adalah berbentuk persegi panjang dengan pipa bulat. Pendekatan atau tahapan penelitian yang dilakukan adalah melalui metode pengujian dan simulasi unjuk kerja kolektor PV/T. Proses pengujian diperlukan untuk mendapatkan data pembanding terhadap hasil simulasi yang dilakukan. Dalam penelitian ini metode pengujian unjuk kerja termal berdasarkan standar EN 12975 yang dilakukan secara indoor dengan menggunakan solar simulator. Proses simulasi menggunakan software CFD (Ansyst Fluent) untuk mengembangkan atau memprediksi unjuk kerja kolektor. Setelah proses validasi, Program Ansyst Fluent yang digunakan dapat diterima untuk mensimulasikan karakteristik kinerja kolektor PV/T karena terdapat perbedaan hasil eksperimen dengan simulasi sekitar 6 %. Lebih lanjut, hasil simulasi menunjukkan bahwa penggunaan pipa persegi mampu meningkatkan efisiensi termal kolektor PV/T dibandingkan dengan penggunaan pipa bundar. Namun terdapat kenaikan nilai pressure drop pada penggunaan pipa persegi lebih tinggi sekitar 11.49% dari pipa bundar.
