💡 Quick Answer: Ground-mounted systems and roof arrays in high-lightning areas (>25 strikes/km²/year) should have dedicated lightning protection. Small residential rooftop systems in low-risk areas often rely on proper grounding and surge protection devices (SPDs) as sufficient. Since the PV system is directly connected to the electrical installation of the building, lightning effects can have severe consequences: Comprehensive protection is therefore necessary and should be planned carefully. Risk analysis – Prerequisite for professional planning Professional planning. While comprehensive research shows solar installations are remarkably resilient to extreme weather, lightning represents one risk factor worth addressing. Due to their conductor loops and installation locations, these systems are at risk from. Photovoltaic arrays are typically installed on rooftops, near power transmission lines, constructed of aluminum frames, and must be free from objects that shade them. Optimum exposure to sunlight also means increased vulnerability during electrical storms.
