Status of a grid-connected MBIPV project in Malaysia

Abstract

This paper discussed the current status of a grid-connected photovoltaic (PV) system installed in Malaysia. There are 97 locations with capacity of array power, which is 857.92 kWp grid-connected PV systems are monitored by the Photovoltaic System Monitoring Centre (PVSMC), UiTM. Since monitoring the performances for grid-connected system, there are several sites had been detected facing problems involve technical problem like an inverter fault, sensor fault and environmental problem such as shading effect and lower energy. All the problem will be affected the PV system performances in terms of final yield and performance ratio thus it will be inclined the data availability problem. Furthermore, it could waste the energy produced by PV array and energy payback period. An established practical knowledge in designing a PV system need to be taken seriously in order to avoid improper design before installation to maximize the energy production. It is very important to structure proper design and sizing procedures, identify the factors which affect the performances and component sizing for PV system to optimize and utilize the energy production before any actual implementation of solar power energy system installed.
