double-edges of BIPV

1. Key Advantages ✅ Space-Saving – Doubles as roofing/facade material without extra land use   ✅ Aesthetic Appeal – Customizable colors, transparency and shapes for architectural integration   ✅ Economic Benefits – Saves conventional construction costs while generating electricity   ✅ Policy Support – Qualifies for green subsidies and meets building solar mandates (e.g., EU's 40% coverage rule)   ✅ Durability – Weather-resistant designs last 25-30 years     2. Key Challenges   ⚠ Higher Cost – 20-40% more expensive than standard PV systems ⚠ Installation Complexity – Requires precise architectural coordination and specialized maintenance ⚠ Efficiency Trade-off – Generates 10-20% less power due to fixed angles and light transmission needs ⚠ Adoption Barriers – Still gaining acceptance among builders and developers
