马来西亚通过向公众推广使用太阳能光伏等可再生能源，以减少对化石燃料能源的依赖，取得了进展。由于对高电费的关注，马来西亚玻璃市大学（UniMAP）热衷于安装太阳能光伏系统，作为其建筑节能计划的一项举措。本文的目的是技术和经济评估不同规模的太阳能光伏系统的大学建筑下的净能量计量（NEM）计划。该研究包括收集太阳能资源信息，建筑物的日负荷分布，光伏阵列与并网逆变器的尺寸以及使用PVsyst软件对所设计的系统进行模拟。根据所获得的结果，每年由负载产生和使用的太阳能的量在年总负载需求的5.10%和20.20%之间。系统产生的几乎所有太阳能都将由负载自行消耗。就获得的利润而言，该大学每年可以减少大约25到100万林吉特的电费，具体取决于规模的大小。有利的是，该大学可以通过每年避免高达2,000吨的二氧化碳排放来为环境保护做出贡献。
Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.
