Abstract

Abstract Auxiliary load in utility-scale PV plants acts as a parasitic load that diminishes the net energy yield exported to the grid. Utilizing solar carports offers a mitigation strategy; however, field-data-based performance studies in tropical climates remain limited compared to simulations. This research evaluates the technical performance and energy self-sufficiency of a 3.3 kWp solar carport at Sengkol PV Plant using field measurement data based on IEC 61724 standards. The analysis covers irradiation, temperature, energy yield, and load profiles. Measurements indicate the system achieved 100% Self-Consumption with no reverse power flow, contributing an average Self-Sufficiency of 10.65%. However, the Performance Ratio (PR) averaged 63.70%, indicating significant thermal losses due to power temperature coefficients when ambient temperatures exceeded 28.5°C. This study confirms that solar carport integration effectively supports the facility's base load, though passive thermal management strategies are recommended to optimize efficiency in low-roof installations
