What is the most typical hazard associated with PV systems?

The most typical hazard associated with photovoltaic (PV) systems is shock. When working with PV systems, various components can carry substantial electrical current. If direct contact is made with energized parts, it can result in electrical shock, which can cause severe injury or even be fatal. Workers and individuals around PV systems must be aware of potential shock hazards, especially during installation, maintenance, and repair of the system.

Electric shock is a prominent concern because a significant aspect of PV systems involves high voltages produced by solar panels, which increases the risk of accidental contact. Safety protocols such as proper grounding, use of personal protective equipment, and adherence to safety training significantly help reduce this risk. Thus, understanding the potential for shock and implementing safety measures is vital for anyone involved in the PV field.

While arc flash, lightning, and earthquakes are also serious hazards, they are less common in everyday scenarios compared to shock. Arc flash can occur due to faults in electrical equipment, lightning can strike the system resulting in surge damage, and earthquakes can affect the structural stability of installations. However, the immediate and frequent risk posed by electric shock makes it the most typical hazard associated with PV systems.
