PHOTOVOLTAIC POWER SYSTEM DESIGN FOR CARAGA STATE UNIVERSITY CABADBARAN CAMPUS, AGUSAN DEL NORTE, PHILIPPINES

This study proposed a segmented photovoltaic power system design for Caraga State University Cabadbaran Campus (CSUCC), Agusan del Norte during the Academic Year 2017 – 2018. Descriptive – Evaluative method of research was employed with energy audit as the primary tool in assessing the recent situation on energy demand and other energy related aspects in the Campus. A survey on the presence of energy conservation initiatives was also undertaken to assess its effect on energy demand. Based on the result of the utility bill audit conducted, the electric bills showed the total electric power consumption of CSUCC for the entire year 2017 was 157,048 Kw/hr. and paid the total amount of P1, 339,782.79. On the conducted walk through audit on the potential loads, the total end use of Caraga State University Cabadbaran Campus (CSUCC) was 267,290 kilowatts. The Other Equipment and Devices (OED) were accounted for 58 percent of the total potential loads. About 33 percent were consumed by the Ventilation and Air-Conditioning units (VAC) while Lighting Fixtures (LF) were accounted for 9 percent of the overall potential loads. Observation of both the faculty and staff on the presence of energy conservation initiatives at CSUCC with 25 respondents in each group selected from the total population using purposive sampling technique disclosed that the average weighted mean of the faculty's observation was 1.62 with a verbal interpretation of Not Observed while the staff's observation had an average weighted mean of 1.58 also with a verbal interpretation of Not Observed. It showed that both faculty and staff were consistent in their observation that most of the listed energy conservation initiatives were not present or practiced at Caraga State University Cabadbaran Campus thus contributing to the steady increase in energy consumption. Findings of the study born out a conclusion that Caraga State University Cabadbaran Campus (CSUCC) generally doesn't have concrete energy conservation initiatives that would help curtail its rising consumption of electricity thus a Photovoltaic Power System is heavily recommended for adoption. It would also help sustain the operation of the frontline offices of the university especially during power interruptions.
