While analyzing the advantages of BIPV (Building Integrated Photovoltaics), it is also necessary to recognize the current challenges it faces:
1. High initial investment cost: Compared with traditional building materials +BAPV, the cost per watt of BIPV is still relatively high, and it has a high initial capital.
2. High technical complexity: It requires close collaboration among multiple specialties, such as architectural design, structure, electrical engineering, and photovoltaic technology at the early stage of the project, which poses higher demands on both the design and construction parties.
3. Efficiency issues: To meet architectural aesthetic and functional requirements, the power generation efficiency of BIPV modules is usually lower than that of standard photovoltaic modules with the same area and the optimal tilt Angle.
4. Standards and norms need to be improved: As an interdisciplinary field, relevant building norms, electrical standards, fire protection norms, etc., are still in the process of continuous development and unification.
5. Post-maintenance and replacement: As a building structure, its repair and replacement are more complex than those of traditional BAPV systems, and maintenance channels and replacement plans need to be considered at the design stage.
Despite the current challenges in terms of cost and technology, with the continuous maturation of technology, the manifestation of scale effects, and the sustained strengthening of policy support, the advantages of BIPV will become increasingly prominent, and the market prospects are very broad.
