How to improve the effectiveness of lightning protection for residential systems?

To enhance the effectiveness of lightning protection for residential systems, the following points, in addition to usual lightning protection measures, should be considered: If the system has a large capacity or is located in an area with high lightning strikes, installing a lightning rod beside the solar array is necessary.

Can a lightning protection system be installed on a flat roof?

If a system is installed on a flat roof, it tends to ground via the inverter cover or connect to the building’s existing lightning protection system. Such lightning protection is potentially inadequate for areas with high lightning probability.

What is a lightning rod?

“Lightning rods” are static discharge devices that are placed above buildings and solar-electric arrays, and connected to ground. They are meant to prevent static charge buildup and the surrounding atmosphere’s eventual ionization. They can help prevent a strike and can provide a path for a very high current to ground if a strike does occur.
