[0002] With the progress and development of society and technology, new energy and clean energy are receiving increasing attention, and green building is also gaining importance in the construction industry. Using solar power to supply electricity for buildings has become one of the development options for green buildings. At the same time, prefabricated construction is also a development direction for green building. Prefabricated construction involves manufacturing most of the building's structure in a factory and then assembling it on-site. This shortens the construction period and reduces the environmental impact of construction. Prefabricated construction is currently mainly used in factory construction.
