Feasibility Analysis of Rooftop Solar Power Generation System in Academic Institution

This research examines the possibility of energy savings using lighting in an academic institution, the Politeknik Sultan Azlan Shah (PSAS), Malaysia. Three of PSAS's primary academic buildings underwent an energy audit to see how much energy was used for lighting. The 3 academic buildings involved are the Mechanical Engineering Department (MED), the Civil Engineering Department (CED), and the Electrical Engineering Department (EED). To determine which lighting types in academic buildings, consume the most energy, this study examines five distinct lighting options. Fluorescent T8 36W, Fluorescent T8 18W, Compact Fluorescent (CFL) 24W, Metal Halide (MH) 400W, and Ttube 18W are the five lighting kinds involved in this study. The calculation of energy savings is predicated on the installation of hybrid solar systems on the three buildings. Based on the energy audit findings, it is predicted that installing a hybrid system that includes a rooftop solar photovoltaic (PV) system will save energy by at least 5% compared to data from the previous year. Potential energy savings in 2019 respectively for MED, CED, and EED obtained through feasibility studies are about 4299 kWh, 2,319 kWh, and 3,269 kWh. Meanwhile, the energy cost savings obtained for MED, CED, and EED are approximately RM 1,569, RM 846, and RM 3,269 respectively.
