What is the most common method of safety when handling PV modules on a roof in sunlight?

The most common method of safety when handling photovoltaic (PV) modules on a roof in sunlight is to ensure that the connectors are open. Open connectors prevent the flow of electricity from the modules, significantly reducing the risk of electric shock or arc flash incidents during installation or maintenance activities. When connectors are not engaged, the modules are effectively isolated from the electrical system, providing a safe working environment.

This practice is essential in the context of safe handling because even in bright sunlight, modules can generate significant voltage and current. By keeping connectors open, workers minimize the hazard associated with accidentally touching live parts or creating unintended electrical paths. Ensuring that connectors remain open is a proactive measure to prioritize electrician safety while working at height and under potentially hazardous conditions.
