This study evaluates the actual performance of an 80.5 kWp rooftop PV system integrated with a Green Hydrogen Plant (GHP) at PLTGU Muara Tawar and validates the results using PVsyst simulation. The evaluation was conducted based on actual operational data during January–December 2025 using parameters of energy production, Performance Ratio (PR), Capacity Factor (CF), and Specific Yield. The results show actual energy production of 104,739 kWh/year with an average PR of 71%, CF of 15%, and Specific Yield of 1,301 kWh/kWp/year. PVsyst simulation predicted a PR of 82.39% with energy production of 120,566 kWh/year, resulting in a deviation of 11.39 percentage points in PR and 13.1% in energy production. The loss diagram analysis identified temperature effects (9.45%) as the main cause of deviation, followed by module mismatch (2.05%), inverter losses (1.81%), and ohmic wiring losses (1.02%). Field factors such as soiling, module degradation, and differences in actual irradiation with the Meteonorm database also contribute to the lower actual performance. This study recommends routine panel cleaning, layout evaluation to minimize mismatch, and module temperature monitoring to bring actual performance closer to its design potential.
