Kajian ini merupakan satu usaha untuk mereka bentuk model sistem fotovoltan (PV) tanpa grid. Proses pemodelan sistem PV ini berdasarkan persamaan matematik dan dijalankan sepenuhnya menggunakan MATLAB/Simulink sahaja. Sistem PV ini mengandungi tiga bahagian utama iaitu, tatasusunan PV, DC-DC converter rangsangan dan motor DC sebagai beban. Setiap bahagian direka bentukkan secara berasingan sebelum menggabungkan kesemua bahagian untuk menghasilkan satu sistem PV lengkap. Kuasa keluaran maximum untuk model ini ialah 10kW. Sistem PV bergantung kepada tahap sinaran,𝐺 dan suhu operasi,𝑇𝑐. Oleh yang demikian, sistem PV ini dianalisis dengan dua keadaan di mana keadaan yang pertama adalah sistem PV diuji dengan berbeza tahap sinaran,𝐺 dan suhu operasi,𝑇𝑐 yang tetap dengan kuasa keluaran 10.470kW (G=1), 5.903kW (G=0.75), 2.624kW (G=0.50) and 0.645kW (G=0.25). Keadaan kedua, di mana sistem PV telah diuji dengan suhu operasi,𝑇𝑐 yang berbeza dan tahap sinaran,𝐺 yang tetap dengan kuasa keluaran 10.470kW (Tc=25°C), 10.430kW (Tc=50°C), 10.350kW (Tc=75°C) and 10.230kW (Tc=100°C). Model sistem PV juga telah diuji dengan purata maksimum dan minimum tahap sinaran dan suhu operasi di Malaysia, dengan kuasa keluaran 10.830kW (G=1.056, Tc=32°C) untuk purata maximum tahap sinaran dan suhu operasi, manakala 0.713kW (G=0.254, Tc=27°C) untuk purata minimum tahap sinaran dan suhu operasi. Ini terbukti bahawa sistem PV ini boleh dipasang di Malaysia.

This research is an attempt to design a model of standalone photovoltaic (PV) system. The modelling process for PV system was based on mathematical equations and fully conducted using MATLAB/Simulink only. The system mainly consist of three main parts which, PV arrays, DC-DC Boost Converter and DC motor as load. Each parts was designed separately before connecting them together to form a complete PV system. The maximum output power for this model is 10kW. The PV system is depending on irradiation level,𝐺 and temperature,𝑇𝑐. Therefore, the PV system was tested and analysed with two condition where the first condition, the PV system was tested with different level of irradiation level,𝐺 and constant operating temperature cell,𝑇𝑐 where the output power obtained were 10.470kW (G=1), 5.903kW (G=0.75), 2.624kW (G=0.50) and 0.645kW (G=0.25). The second condition, where the PV system was tested with different operating temperature cell,𝑇𝑐 and constant irradiation level,𝐺 with the output power obtained were 10.470kW (Tc=25°C), 10.430kW (Tc=50°C), 10.350kW (Tc=75°C) and 10.230kW (Tc=100°C) The PV system model also has been tested with maximum and minimum average irradiation level and temperature in Malaysia, where the output power obtained were 10.830kW (G=1.056, Tc=32°C) for maximum average irradiation level and temperature, while 0.713kW (G=0.254, Tc=27°C). This result proved that the PV system can be installed in Malaysia.
