A Feasibility Study on the Installation of Solar Photovoltaic (PV) Rooftop System for the Pangasinan State University

Abstract

Pangasinan State University particularly the Urdaneta City Campus, Sta. Maria Campus, Binmaley Campus, and Infanta Campus uses more than590,000-kilowatt-hours (kWh) of electricity annually. The PSU is searching for ways to lessen the cost and effect on the environment-related with their activities. One feasible alternative is solar energy use to produce electricity on the four (4) campuses. Solar power, however, is a complex issue for an enormous project in particular. Taking the time to assess alternatives before starting a project of this scale, it is possible to save money and effort in the future. This research is intended to verify the probability and connected benefits from solar PV rooftop system installation equals to the generation capacity on its campuses. Solar PV data were determined to compute the complete estimated quantity of electricity each solar power system would generate yearly. Cost information was used to evaluate each system’s cost from the Solar Philippines and the cost of electricity per kWh from each and every solar energy system and from different distribution utility for each campus. Another, University space and energy usage data particularly from the Office of the University Engineer were used to verify the size and capacity of the required solar power systems and the accessibility of campus space. Additionally, talks and consultations with the Campus Executive Directors, Coordinator for Physical Facilities, and the Campus Accountant were used to assess both financial and non-financial advantages from the university's use of solar. A solar photovoltaic rooftop system, the cheapest choice has been proven, with a nine and a half (9.5) years payback period and a cost of 10 PHP (Philippine Peso) per kWh. With the available at the moment,3,360 square meters of rooftop space that can be used, up to 336,000 kWh or 57% of the four (4) campuses,2018electricity usage could be produced with solar energy. Non-financial advantages include decreased environmental impact, possibilities for teaching and learning, a symbol of sustainability engagement, energy security, and brand advertising. The University cannot produce 100% of its energy from solar power installations on campuses. Furthermore, compared to current electricity rates, solar electricity is somewhat expensive. Nevertheless, having a power purchase agreement with the Solar Philippines Inc., (SPI), and the University can install solar PV rooftop system at no cost at all and will also have an outright saving of 38% on a monthly electrical bill, and given the non-financial benefits, solar PV rooftop system installation on the said four (4) campuses should be considered by the University.
