Data masukan :
Rerata kecepatan angin (Vm) = 4,8 m/s
Daya turbin yang digunakan = 1 Kw
Rated Speed (Vr) = 6 m/s
Cut - Out Speed (Vf) = 10 m/s
Rasio Cut-Out/Rated Speed = 10 : 6 m/s
(Vf/Vr) = 1.67 m/s
Rasio Av Speed/Rated Speed = 4,8 : 6 m/s
(Vm/Vr) = 0,8 m/s
Daya Output = 0,46 Kw
Daya Output Rerata = 0,46 x Rated Output
= 0,46 x 1
= 0,46 Kw
Annual Energy Generation = 0,46 x 24 x 365 Kwh
= 4029,6 Kwh
Jika 1 Kw dihargai Rp 1000,00
Pendapatan tiap tahun 1000 x 4029,6 = 4.029.060,00
1 Unit generator x Rp 8.000.000,00 = 8.000.000,00
Pembuatan Pondasi Tower = 2.000.000,00
Pembuatan Tower = 3.000.000,00
Biaya perawatan 10 tahun = 20.000.000,00
= 38.560.800,00
Biaya lain-lain (array loses, etc) 10% = 3.856.080,00
Total = 42.416.880,00
Investasi = 42.416.880,00
Interest Bank 12 % = 5.090.026,00
Total = 47.506.906,00
Pendapatan 10 tahun dari energy kincir angin
= 4.029.060,00x 10
= 40.290.060,00
Kesimpulan :
Investasi TIDAK LAYAK
Investasi akan layak bila harga > Rp. 1.380,00/Kwh
