Building Integrated Photovoltaics (BIPV) combines solar technology with building construction, allowing buildings to generate electricity and be more energy-efficient. BIPVs can replace traditional architectural glass in roofs, skylights, and facades, providing power generation, transparency, and insulation. This technology helps in creating smart cities and utilizing renewable energy sources. Although BIPVs are more expensive than solar thermal systems, they offer free and clean energy, maximizing a building's performance.
