Proposed Solar Energy Plan in NDDU-Glamang Campus

This study explored the viability, economic potential, and environmental impact of implementing a solar photovoltaic (PV) system at Notre Dame of Dadiangas University – Glamang Campus (NDDU-GC). Using secondary data and institutional energy records, the research estimated that a 344-kW system, composed of 860 panels installed on a 1,723.459 m² rooftop, could generate between 450,775 and 565,020 kWh of electricity annually. The estimated installation cost was PHP 18.92 million, with projected annual savings of PHP 6.01 million based on prevailing electricity rates. The investment was projected to break even within three to five years. The transition to solar energy was also expected to reduce carbon emissions by over 360,000 kg per year, bringing notable environmental benefits, such as decreased fossil fuel reliance and lower greenhouse gas emissions. In addition to economic and environmental gains, the project supported local employment by requiring full-time maintenance personnel. The findings emphasized the potential of academic institutions to lead in clean energy initiatives and climate action. It was recommended that NDDU-GC expand solar adoption across additional campus facilities and use the project as a platform to strengthen environmental education. Promoting awareness through campus-wide campaigns, integrating sustainability topics into academic programs, and engaging both internal and external stakeholders were also encouraged. Finally, it was advised that system performance be continuously evaluated, and future innovations—such as energy storage or smart grid integration—be considered to enhance long-term efficiency and sustainability further.
