Photovoltaic systems are at risk of lightning strikes due to their outdoor installation. Lightning can directly hit these systems or damage them through induction. To protect photovoltaic systems from lightning and overvoltage, appropriate protection systems must be used.

Types of protection systems:

• External protection system: It consists of a lightning rod, down conductor, and earthing system.
  • Lightning rod: It captures lightning and converts it into electrical current.
  • Down conductor: It conducts the electrical current from the lightning rod to the ground.
  • Earthing system: It disperses the electrical current into the ground and prevents it from spreading into the environment.
• Internal protection system: It protects the electronic equipment inside the photovoltaic system from induced voltages and overvoltage.
  • Equipotential bonding: This process involves connecting all metal parts of the photovoltaic system together to prevent potential differences between them and sparking and arcing.
  • Use of surge protection devices (SPDs): These devices protect electronic equipment from damage by diverting excess voltage to ground.
  • Maintaining a safe distance: This involves keeping a safe distance between the photovoltaic system and other conductive objects such as chimneys, antennas, and trees to prevent induction and damage to the system.

Choosing the right protection system:

The choice of the appropriate protection system for photovoltaic systems depends on various factors, including the size and type of system, the climatic conditions of the region, and the type of structure on which the system is installed. To select the right protection system, it is necessary to consult with experienced specialists and experts in this field.

Benefits of protecting photovoltaic systems:

• Increased system lifespan
• Reduced maintenance costs
• Prevention of outages and production losses
• Increased safety and reliability of the system
