Prefabricated buildings include prefabricated PC (precast concrete), prefabricated steel structures, and modular buildings (including two major product series: PC and steel structures). Modular buildings, through a systematic solution of "standardized design, factory production, assembly construction, and information management," create "good houses" that not only meet the Ministry of Housing and Urban-Rural Development's "6633" standards but also benchmark against international standards, achieving efficient control and quality traceability throughout the entire lifecycle of building industrialization, and significantly improving construction efficiency and building quality.

Modular building is a modern construction solution based on factory prefabrication and on-site assembly. By producing standardized modules in a controlled manufacturing environment and transporting them to the site for installation, this approach improves construction efficiency, quality consistency, and resource utilization. Compared with conventional construction methods, modular building offers advantages in faster delivery, reduced on-site work, better cost control, and more sustainable project execution. It is widely applied in residential, commercial, educational, healthcare, and hospitality projects.

Rooftop photovoltaic modules absorb sunlight during the day to generate direct current (DC) green electricity, which is then converted into alternating current (AC) green electricity for direct use by household loads. String/modular energy storage systems store the green electricity not consumed during the day and discharge it at night for nighttime use.
