Building-Integrated Photovoltaics: A Technical Reality Check (heise.de)

• Rooftop PV maximizes annual energy generation
• Façade PV enhances daily production alignment
• Technical and regulatory barriers limit deployment

"Building-integrated photovoltaics (BIPV) offer improved generation profiles throughout the day compared to rooftop systems, which prioritize total annual yield. While technology has matured, widespread adoption is constrained by high installation costs and complex building physics requirements that limit architectural scalability and financial viability."
