Feasibility analysis of rooftop solar photovoltaic for non-academic building in an educational institution in Malaysia

Abstract

An educational institution is one of the sectors that consume a high amount of energy. An identify the energy consumption gives information to forecast the energy saving. The research aims to utilize rooftop solar photovoltaic (PV) at non-academic buildings in Malaysia’s educational institution. A detailed energy audit has been conducted at Politeknik Sultan Azlan Shah (PSAS) involving three non-academic buildings to identify the buildings’ energy usage. The three different building involved is the Islamic Centre (Mosque), Sports Centre, and Multipurpose Hall. The energy audit analysis is divided into four end-load groups comprising lighting, fans, air conditioning, and other equipment to identify each type of load’s energy consumption. Which equipment consumes the highest amount of energy in non-academic buildings in PSAS is determine. The results show that the highest energy consumption at the Islamic Centre and Multipurpose Hall is an air conditioner for a while Sports Centre is lighting equipment. Annual power generation and energy bill savings are calculated based on rooftop solar PV installation for self-consumption. From the feasibility analysis, the forecast of energy-saving for at-least 5% per year has been estimated. It significantly reduces the amount of carbon emission release to the environment.

Modeling and analysis of rooftop solar photovoltaic system for educational institution in Malaysia

“…The average peak sun hour in normal conditions is 4-6 hours, as mentioned the [11], while [12] states between 4.0 to 5.4 hours, depending on the location. Despite Malaysia's year-round hot and humid weather, the research's average peak sunlight hours were only calculated to be 4 hours [5,13]. Based on the results of most studies, which indicate that 4 hours is the lowest value, the calculation's reason for choosing this number is grounded in this.…”
