<![CDATA[The performance of grid-connected photovoltaic (PV) systems is influenced by several technical and environmental factors, particularly solar irradiance, inverter performance, and installation site characteristics. This study aims to analyze the performance of a 60 kWp grid-connected photovoltaic system based on solar irradiance, inverter efficiency, and site suitability at PT. Bernadi Utama. The research was conducted using operational monitoring data collected from the installed PV system and simulation results generated using PVsyst 7.4. The evaluated performance parameters included Global Horizontal Irradiance (GHI), AC and DC power, inverter efficiency, energy production, and Performance Ratio (PR). In addition, site suitability was assessed through shading analysis and solar resource availability to determine the feasibility of the installation location. The results indicate that solar irradiance is the primary factor affecting photovoltaic power generation, where higher irradiance levels produce greater electrical output. The inverter demonstrated stable performance during the observation period, while the performance ratio remained within an acceptable range for grid-connected photovoltaic systems. Furthermore, the comparison between measured and simulated results showed good agreement, indicating that the PVsyst model can reliably predict system performance. Overall, the installation site exhibited favorable solar resource availability and minimal shading, supporting efficient and stable long-term photovoltaic operation.]]>
