The rooftop solar panel systems not only brings clean electricity, but also helps to reduce the amount of heat shining directly on the ceiling, causing heat to the air inside the house. This paper has performed simulation models by using a computational fluid dynamics (CFD) in combination with Monte-Carlo method to determine the ceiling and solar panel temperature values in different climatic conditions of the Hanoi city, Vietnam. The analysis results show that installing solar panels on the roof can reduce up to 12.0oC for the inside air of the house, thereby saving electricity consumption from the use of air conditioners or ventilation fans during the hot season. In addition, this research also contributes to the temperature data of the panels in specific conditions in Hanoi, helping to ensure the safety and performance of the systems.
