UL3703: Standard intended for Photovoltaic Module Safety Overview: UL3703 addresses the safety requirements for photovoltaic (PV) modules and assemblies. It focuses upon ensuring that solar power modules can tolerate environmental conditions and operate safely more than their intended life expectancy. Key Points: Mechanised Integrity: Tests for strength against breeze, snow loads, and even mechanical stresses. Electric powered Safety: Ensures correct insulation, grounding, in addition to prevention of electrical hazards
