This paper presents a detailed target-oriented performance assessment of a 232.5 kWp grid-connected solar PV (GCPV) system installed on a commercial building in Malaysia. Technical and meteorological data for 2019, in 5-min intervals, was retrieved from the solar data logger. The GCPV system generated about 301.5 MWh of energy in 2019, almost achieving the stated target of 305.0 MWh. While most months in 2019 successfully achieved the set monthly target, some did not due to low solar irradiance. The Performance Ratio (PR), Capacity Utilization Factor (CUF), system efficiency, and Levelized Cost of Energy (LCOE) were found to be 85.4%, 14.85%, 9.15%, and 0.396 MYR/kWh, respectively. The PR of the present GCPV system was higher than other GCPV systems surveyed. Approximately 177 metric tons of CO₂ emissions were saved during the year after installing the GCPV system. In addition, performance models, based on the key factors of solar irradiation and PV module temperature that affect the yield and power output of the GCPV system, were developed and tested statistically. The findings of this study should be of use to solar energy customers and stakeholders.

本文对安装在马来西亚一幢商业建筑上的232.5 kWp并网太阳能PV（GCPV）系统进行了详细的针对目标的性能评估。从太阳数据记录器中检索了2019年的技术和气象数据，间隔为5分钟。GCPV系统在2019年产生了约301.5 MWh的能源，几乎实现了305.0 MWh的既定目标。尽管2019年的大多数月份都成功实现了每月设定的目标，但有些月份并不是由于太阳辐照度低而造成的。发现性能比（PR），容量利用率（CUF），系统效率和能源平均成本（LCOE）分别为85.4％，14.85％，9.15％和0.396 MYR / kWh。当前GCPV系统的PR高于调查的其他GCPV系统。约177公吨的CO ₂安装GCPV系统后，一年内节省了排放。此外，基于影响GCPV系统产量和功率输出的太阳辐射和PV组件温度的关键因素，开发了性能模型并进行了统计测试。这项研究的结果应该对太阳能客户和利益相关者有用。
