Comprehensive Assessment of Roof-Mounted Solar Photovoltaic Systems with Varying Tilt Angles: Case Study at the USTP Claveria Campus Gymnasium

Colleges and universities, including the USTP Claveria campus, face high electricity costs due to significant daily energy consumption for campus operations. This research addressed the gap in sustainable energy solutions by designing an optimal roof-mounted solar photovoltaic (PV) system to reduce reliance on utility electricity and mitigate carbon emissions. The study assessed the campus's energy consumption and roof space, evaluated solar energy potential using NASA POWER Project data, and designed a cost-effective and structurally viable PV system. Methodologies include site and building assessments, solar energy analysis, and system design utilizing Helioscope and AutoCAD software. Considering tilt angles of 6°, 9°, 11°, and 14°, the proposed 216 kW PV system, composed of 432 modules, is projected to generate 458,648.41 kWh annually. This energy output surpasses the campus's daily load requirements, offering scalability for future energy demands and potential distribution to the nearby community. Implementing this PV system will provide a sustainable, cost-effective solution to rising electricity costs and support USTP Claveria's sustainability goals while enhancing community energy resilience.
