The integration of renewable energy systems, particularly rooftop solar panels, in industrial buildings has increased as part of efforts to improve energy efficiency and sustainability. However, the installation of solar panels on a Pre-Engineered Building (PEB) introduces additional permanent loads that may affect structural performance. This study aims to evaluate the effect of solar panel installation on the structural performance of a PEB warehouse in Medan. The analysis was conducted by comparing the existing structural condition with the condition after the addition of a solar panel load of 0.15 kN/m². A structural model was developed using structural analysis software, while the evaluation considered the utilization ratio (UR) of selected structural members, including the main column, rafter haunch, roof purlin, rafter mid span, and end wall column. The results indicate that solar panel installation increases the utilization ratio of all evaluated structural members. The roof purlin experienced the highest increase, from 0.74 to 0.91, corresponding to 22.97%, while the rafter haunch showed the lowest increase of 11.54%. The critical structural member also shifted from the main column in the existing condition (UR = 0.79) to the roof purlin after solar panel installation (UR = 0.91). Nevertheless, the maximum utilization ratio remains below 1.00, indicating that the evaluated structural members remain within their design capacity. The findings demonstrate that rooftop solar panel installation can be implemented on PEB structures with appropriate structural assessment and load evaluation.
