In China, entire skyscrapers are being wrapped in building-integrated photovoltaics (BIPV)—solar panels embedded directly into walls, windows, and facades. These high-rise buildings now function as vertical power plants, generating electricity while occupying no additional land. Vertical solar is especially valuable in dense cities where rooftop space is limited. Modern BIPV panels are designed to be lightweight, semi-transparent, and aesthetically integrated into architecture, allowing building
