Modul fotovoltan adalah antara salah satu teknologi tenaga boleh diperbaharui yang
mahal dan mempunyai tingkah laku yang kompleks serta ciri-ciri tidak linear dalam keadaan
persekitaran yang berbeza. Oleh itu, simulasi reka bentuk model adalah penting untuk
menentukan hubungan antara arus, voltan dan kuasa modul fotovoltan pada keadaan persekitaran
yang berbeza. Dalam projek ini, satu model fotovoltan diod tunggal direka dengan menggunakan
perisian Matlab / Simulink blok untuk mensimulasikan prestasi modul fotovoltan rujukan.
Fotovoltan BP275F dipilih sebagai modul fotovoltan rujukan kerana ia telah digunakan secara
meluas di Pusat Pengajian Kejuruteraan Elektrik dan Elektronik, (SEEE), USM. Data sinaran
solar dan suhu dikumpulkan selama 7 hari menggunakan panel fotovoltan yang terletak di atas
bumbung SEEE. Lima parameter yang digunakan untuk mereka bentuk model fotovoltan dalam
projek ini adalah arus tepu ke belakang, arus foto, factor idealistis diod, rintangan siri dan
rintangan selari. Hasil simulasi menunjukkan bahawa ciri-ciri I-V dan P-V model fotovoltan ini
selari dengan dengan helaian data modul fotovoltan. Kesan perubahan sinaran solar dan suhu
kepada model fotovoltan juga dikaji dan ianya terbukti bahawa ciri-ciri model fotovoltan selari
dengan teori. Kemudian, model fotovoltan ini digunakan untuk menganalisis berdasarkan
keadaan persekitaran di SEEE menggunakan sampel data purata untuk setiap jam. Pada waktu
kemuncak sinaran cahaya, modul fotovoltan dijangka boleh menghasilkan kuasa maksimum
sebanyak 54.12W dan kuasa minimum sebanyak 31.56W. Fotovoltan ini dianggarkan dapat
membekalkan kuasa sebanyak 417.8Wh dalam sehari di Pusat Pengajian Elektrik dan Elektronik
(PPKEE), USM.

Photovoltaic (PV) module is one of the most expensive renewable technologies which
has complex behavior and nonlinear characteristics in different surrounding conditions.
Therefore, the design of a simulation model is necessary to determine the relationship of current,
voltage and power of PV module at different surrounding condition. In this project, a single diode
model of PV module is designed by using Matlab/Simulink block to simulate the performance of
selected module which is BP275F PV module. This module is selected as the reference PV module
as it has been widely used at the School of Electrical and Electronic Engineering, (SEEE), USM.
The data for solar irradiance and temperature are collected from PV panels located at roof top of
SEEE for 7 days. The five parameters that are used to design the PV model in this project are
reverse saturation current, photocurrent, diode ideality, series resistance and parallel resistance.
The simulation results show that I-V and P-V characteristics of this PV model matched closely
with the PV module datasheet. The effect of variation of solar irradiance and temperature to the
PV model are analyzed and it is proved that the characteristics of this PV model matched well
with the theory. Therefore, this model can be used to estimate the performance of PV module at
different surrounding condition. Then, the PV model is used to analyze the behavior of
surrounding irradiance and temperature at SEEE using sampled average data for every hour. The
result from the data collection shows that this PV module can produce power with maximum
value 55.51W and minimum value 36.18W at peak hours. It is estimated that PV module can
gives output power of 417.8Wh in a day at the School of Electrical and Electronic Engineering,
(SEEE), USM.
