Assessment of a Solar PV System Installation on the Roof of a Building

In recent years, there has been a growing trend to install solar panels on the roofs of buildings in Ulaanbaatar. These systems play an important role in improving the independence of electricity supply and reducing urban greenhouse gas emissions. Some roof surfaces in urban buildings are unsuitable for installing solar systems. This study assessed the suitability of solar energy resources and installing solar power systems on the roofs of buildings in urban areas. It also identifies factors affecting the roof that are suitable for installing a solar electrical system. The 15 kW system installed on the roof of the 8th building of the MUST was designed using PVsol software, and the results were developed. The solar energy level on the roof of the building is Ri = 0.78, indicating that it is a highly suitable roof for installing solar power systems.
