Design installation and testing results of 1 kWp amorphous-silicon FS GCPV system at UiTM, Malaysia

Abstract

This paper focuses on a Grid-Connected Photovoltaic (GCPV) system of amorphous Silicon (a-Si) PV module technology with total PV capacity is about 1.179 kWp. This a-Si FS GCPV system is located near to the Green Energy Research Centre (GERC) Building at Universiti Teknologi MARA (UiTM) Shah Alam, Malaysia. This a-Si FS GCPV system installation was referred to Malaysian Standard MS1837:2010 and designed based on initial data values. These days, various of the GCPV system applications in Malaysia using thin-film PV module technology was designed at stabilised data values. So, this a-Si PV system is conducted to study the PV performances and behaviors under Malaysia's perspective. After the observation period, a-Si FS GCPV system performs in good condition. The PV system generated 644.40 kWh electrical energy during the first six months of operation (June-December 2011) and the average daily energy yield of 3.03 kWh. The average monthly final yield was found to be 78.0 kWh/kWp, while the range of the initial/stabilized performance ratios between 55.8% to 78.2% and 73.0% to 102.4%.Index Terms-amorphous-Silicon (a-Si); Free-standing (FS); Grid-connected inverter; Initial system design; Photovoltaic (PV); Thin-film (TF).

“…However, the real installed inverter has AC nominal inverter power of 4200W bigger than the maximum estimation of SEDA's method which is 3840W. The analysis of the findings shows that the installed inverter is oversized about 9% from the maximum estimation of nominal inverter power, hence there is no possibility of clamping power occurrence [25]. Thus, the inverter will operate well and has longer lifespan.…”
