A Brazilian roofer cleaning solar panels contacted a high-voltage line, fell and fractured bones; his helper jumping to assist also sustained lower-limb injuries.

Social Context

This parallels China’s ‘Green Energy Worker Safety Directive’ (2023), mandating insulated tools, lockout-tagout procedures, and mandatory spotters for rooftop PV maintenance. Chinese solar firms operating abroad must comply with host-country electrical codes plus home-country safety baselines.

Safety Tip

Always de-energize solar arrays before maintenance—and use Class 00 rubber gloves tested to 1,000V, verified monthly per IEC 61482 standards.
