There are 113 sites with total PV capacity power, of 1008.73 kWp GCPV systems are monitored by the Photovoltaic Sys- tem Monitoring Centre (PVSMC). This paper focus on the PV system performances under Malaysian Building Integrated Photovoltaic (MBIPV) project which relates the performance of the system failures due to technical and environmental factors. Both factors will contribute to the reduction of the PV system performances in terms of final yield. It would later lead to energy inefficiency as the energy harvested from PV array will be wasted which later cause the time taken for en- ergy payback period of the system to be lengthen. Proper and sufficient practical knowledge in designing a GCPV system is needed in order to achieve maximum energy production. A database with minimum period of 4 years was selected as the benchmark for problem identification at PVs site in hot and humid climate. All issues affecting the system performances and BOS component of the GCPV system for optimization purpose. %K Photovoltaic (PV) %K Grid-Connected (GC) %K Malaysian climate %K Building Integrated Photovoltaic (BIPV) %U http://article.sapub.org/10.5923.j.ep.20120203.03.html
