Abstract
Kebutuhan energi semakin lama semakin meningkat dan sumber energi utama yang digunakan saat ini mempunyai keterbatasan untuk memperbaruinya. Photovoltaic adalah komponen semikonduktor yang berfungsi mengkonversi energi matahari menjadi energi listrik. Cahaya matahari yang termasuk sumber energi primer tersedia sepanjang tahun di semua tempat di permukaan bumi. Tingkat penyinaran yang berbeda-beda menyebabkan daya keluaran dari photovoltaic bervariasi. Karakteristik V-I sel surya adalah nonlinier, berubah terhadap intensitas dan temperatur permukaan photovoltaic. Secara umum, terdapat titik yang unik pada kurva V-I atau kurva P-V, yang dinamakan Maximum Power Point (MPP). Titik MPP tersebut tidak diketahui namun dapat dicari dengan algoritma penjejak atau algoritma MPPT. Pada tugas akhir ini dilakukan perancangan penelusuran daya maksimum menggunakan kontrol logika fuzzy. Sistem penelusuran daya maksimum yang menggunakan modul BPSX-60 dapat menghasilkan daya 59,4W pada keadaan standard condition (intensitas 1000W/m2 dan temperatur 250C). Sistem penelusuran daya maksimum pada panel photovoltaic mampu menelusuri daya maksimum dengan kondisi lingkungan (intensitas cahaya matahari dan temperatur pada permukaan panel photovoltaic) yang berubah-ubah.
