Multi-pulley transmission self-adapting building photovoltaic skin

The adaptive building photovoltaic (PV) skin system, which uses a multi-pulley drive, utilizes a motor-driven steel cable to move a sliding frame to achieve flexible folding of PV units. This solves the problem of integrating PV panels with the building facade, achieving the energy-saving and carbon-reduction goals and aesthetic effects of zero-carbon buildings.
