Feasibility Analysis of Solar Power Generation System for Office Building in Academic Institution

Abstract

This paper study the potential of energy-saving through lighting located at the office building in an academic institution known as Politeknik Sultan Azlan Shah (PSAS). Exercise through energy audit has been conducted at 3 main academic building to identify energy usage of lighting. 3 academic building involved is Mechanical Engineering Department (MED), Civil Engineering Department (CED), and the Electrical Engineering Department (EED). This study analysis 5 types of lighting to identify which types of lighting use the highest amount of energy in academic buildings. The 5 types of lighting involved in this study are Fluorescent T8 36W, Fluorescent T8 18W, Compact Fluorescent (CFL) 24W, Metal halide (MH) 400W and Ttube 18W. Energy savings are calculated based on the installation of hybrid solar in 3 related buildings. From an energy audit, the energy-saving at-least 5% from previous data has been estimated through the installation of a solar photovoltaic (PV) system. Through feasibility analysis, it is found that energy-saving potential obtained in the year 2019 for MED, CED and EED are about 4299 kWh, 2,319 kWh and 3,269 kWh respectively. Besides, the energy bill saving obtained is about RM 1,569, RM 846 and RM 3,269 respectively for MED, CED, and EED.
