Abstract:
This research aims to assess the suitable rooftop area with a potential for solar PV rooftop installation in the case study area of Chulalongkorn University. Determine the suitable buildings with potential by applying the limitations of solar rooftop such as roofing structural and shading that affects system energy production. Employ the geographical information system and software to evaluate the total rooftop area and the technical potential of the PV system. In conclusion, the result represents that 87 out of 216 buildings in Chulalongkorn University are suitable for solar PV installation. The total rooftop area is approximately 115,400.99 sq.m. However, only 23,076 PV panels are applicable for installation (approximately 46,590.44 sq.m). Therefore, the overall annual energy production of all buildings is approximately 13,473.03 MWh. The system annual production can reduce the energy approximately 26.49 percent of the total energy consumption in the campus and save around 66,556,768.2 THB per year.
