Abstract

Renewable energy is widely used to replace conventional energy as conventional energy has negative impact on environment. A few common renewable energy are solar energy, wind energy, biomass energy, geothermal energy, etc. Solar energy has been extensively used in Malaysia as this country has climate of hot and humid throughout the year. In this few years, it can be seen an increase in installation of solar farms and rooftop solar system in Malaysia. Rooftop solar system is more suitable for urban area as it is installed on buildings’ rooftop and does not required additional area. Thus, this project was conducted to design rooftop solar system in Faculty of Engineering, UNIMAS buildings. PVSyst 7.2 software was used to simulate and evaluate the design of grid -connected PV system while Meteonorm 8.0 for climate data collection. Apart from that, power demand was determined using Fluke 435 as sizing of PV system was based on power demand. In the simulation, types of solar panels were varied to investigate which gives best performance of PV system. Specifications of inverter were remained the same throughout the simulation. Results show that to meet power demand of the building, 105kW of PV system with 525 of Si-Mono 200Wp 24V and nine 9.0kW inverters gives the highest Performance Ratio and thus, such design was chosen for this project.
