Abstract: Photovoltaic technology is widely used around the worlds in locations with scarce power generation options. It is used for various applications and Building Integrated Photovoltaic system is one of them. However, photovoltaic are still expensive compared to conventional methods of generating electricity. So, a careful design of the system is required to ensure economic viability. This study describes a preliminary investigation of a Solar PV System for residential applications in Bandar Sri Iskandar. Sizing procedures based on the peak sun hour concept is described for a Malaysian typical terraced house. Current and voltage measurements of the solar panel were carried out to predict the output under actual conditions at site.
