HARNESSING THE SUN: ASSESSING THE IMPACT AND EFFICIENCY OF SOLAR PANELS AT SAINT LOUIS COLLEGE

This study investigates the impact and operational efficiency of the solar photovoltaic (PV) system installed at Saint Louis College, focusing on reducing energy costs and carbon emissions. As part of the institution's broader sustainability initiatives, the solar PV system demonstrates the potential of clean energy integration in higher education. However, challenges related to seasonal variability and weather-dependent energy generation remain. A mixed-methods approach was employed to assess performance and identify areas for optimization—combining quantitative data on energy output, storage, and cost savings with qualitative insights gathered through stakeholder interviews and surveys. Conducted from December 12–16, 2024, in collaboration with the College Development and Sustainability Office, the case study revealed that the 200.34 kW system, installed in 2016 at the cost of Php 15,063,500, supplies roughly 33.3% of the college's total energy demand. Despite increased consumption due to on-site learning and new infrastructure, the system saves approximately Php 1,001,637.57 annually. With average maintenance costs of Php 92,500, the system remains financially viable and is projected to achieve a full return on investment by 2035. Key recommendations include appointing an in-house technical expert for timely repairs and enhancing system performance. The findings underscore solar energy adoption's financial and environmental advantages in academic institutions and suggest practical strategies for improved sustainability.
