Why Lightning Protection Matters for Solar-Integrated Buildings

As photovoltaic (PV) curtain walls become mainstream in modern architecture, lightning protection has emerged as a critical safety consideration. Imagine a sleek office tower where solar panels double as exterior cladding – while it looks futuristic, this integration creates unique electrical risks during thunderstorms. Let’s explore how to balance energy generation with robust lightning safety.

Industry-Specific Challenges

• Heightened exposure: Tall buildings with conductive metal frameworks
• Complex electrical pathways: Interconnected PV arrays acting as potential lightning channels
• Material compatibility: Balancing photovoltaic efficiency with lightning dissipation needs
