Analytical performance monitoring of a 142.5kWp grid-connected rooftop BIPV system in Singapore

Comparative performance investigation of mono- and poly-crystalline silicon photovoltaic modules for use in grid-connected photovoltaic systems in dry climates

“…Another experimental performance study is that of Wittkopf et al [19]. In the frame of that study, the first zero-energy office building in Singapore used the 142.5 kWp p-Si grid-connected system on the roof of the building to meet its energy target.…”

Zigbee-based data acquisition system for online monitoring of grid-connected photovoltaic system

“…For PV system, measurements of the solar radiation, PV voltage and current are almost unavoidable. Depending on whether the PV system is stand-alone PV system (Benghanem, 2010;Forero et al, 2006;Gagliarducci et al, 2007;Krauter, 2004;Park et al, 2012;Ranhotigamage & Mukhopadhyay, 2011;Soler-Bientz et al, 2006) or a grid-connected PV system (Anwari et al, 2011;Ayompe et al, 2011;Boonmee, Plangklang, & Watjanatepin, 2009;Carullo & Vallan, 2012;López et al, 2012;Pietruszko & Gradzki, 2003;Wittkopf, Valliappan, Liu, Ang, & Cheng, 2012), a different sets of additional measurements are required. For the former, parameters related to battery and/or loads are usually needed; while for the latter, parameters related to the grid, i.e.…”

“…In (Park et al, 2012), Autobase is used for programming the PLC in the developed SCADA system. For numeric calculation and analysis, MATLAB (Benghanem, 2009b;Wittkopf et al, 2012) is a popular choice of software. System design software such as LabVIEW (Anwari et al, 2011;Benghanem, 2009a;Benghanem, 2010;Carullo & Vallan, 2012;Forero et al, 2006;Gagliarducci et al, 2007;López et al, 2012;Soler-Bientz et al, 2006) is commonly used, as it provides various comprehensive measurement and control tools in a single application package.…”

Solar façades: A review

“…Wittkopf et al [9] analyzed the performance of 142.5 kW P gridconnected BIPV systems installed on office buildings in Singapore by analyzing the measured values obtained over a period of 18 months using the International Electrotechnical Commission (IEC) standard 61,724, and they found that the average array yield was 3.86 h/d, and the resulting final yield was 3.12 h/d after the capture and system losses (0.58 h/d and 0.16 h/d, respectively) were deducted. The system and array efficiencies are 11.2% and 11.8%, respectively, and the nameplate PV module efficiency is 13.7%.…”
