Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or façades. [1] . The roof is covered with solar panels. [1] They are increasingly being incorporated into the. . PV systems can generate electricity at remote utility-operated "solar farms" or be placed directly on buildings themselves. Their fuel source is simple sunlight, and they produce electricity without the negative environmental consequences associated with other power generation methods. Unlike traditional solar panels mounted on rooftops, BIPV systems are incorporated into the building envelope—roofs, facades. . As the world moves toward cleaner, smarter, and more sustainable energy systems, Building-Integrated Photovoltaics (BIPV) is rising as a game-changer in both architecture and renewable energy.
