Abstract: This study examines the energy generation and long-term sustainability of the solar photovoltaic (PV) system at Notre Dame of Dadiangas University (NDDU), which has been operational since 2017. The research evaluates energy production trends from 2021 to 2023, highlighting a gradual decline in output due to aging components, environmental factors, and maintenance challenges. Key issues include dust accumulation, high temperatures, and shading from nearby structures, which have contributed to efficiency losses. Additionally, the study identifies difficulties in replacing damaged panels, as the original models are no longer available, limiting system upgrades. Findings suggest that preventive maintenance, automated cleaning, and panel repositioning could enhance performance. Moreover, the study underscores the need for a more efficient maintenance approval process to minimize delays that impact energy production. Addressing these challenges is essential to ensuring optimal system performance and long-term sustainability. The study provides valuable insights into institutional solar energy management, offering recommendations that support energy efficiency and sustainability goals. By implementing strategic interventions, NDDU can maximize the lifespan of its solar PV system, reinforcing its commitment to renewable energy.
