Simulation and Economic Analysis of Photovoltaic Rooftop System on the Female Dormitory

Solar energy is an ordinary type of renewable energy accustomed to produce electricity. However, the photovoltaic system may confront risks and uncertainties for operation. King Mongkut’s University of Technology North Bangkok, Rayong campus (KMUTNB), situated in an area which is suitable for photovoltaic installation, plans to expand their alternative energy proportion. This research focuses on the design and economic feasibility of the photovoltaic rooftop system on the female dormitory. By using the System Advisor Model (SAM) program simulation, the total capacity of the panels is found to be about 198.23 kWp with a total electricity production of about 281.827 MWh per year. The economic results revealed that the photovoltaic rooftop system has the potential to produce electricity at a competitive price. The cost of energy is obtained for 0.1297 USD per kWh throughout the project’s life, meaning that the project would serve as a means of reducing 3,535.7327 tons of carbon dioxide equivalent
