6 FAQs about [How to connect the photovoltaic bracket to the lightning protection network cable]

How can a PV system protect against lightning?

The paper recommends modifying the system performance against lightning by the proper cable arrangement, using PV systems with a metal frame, using the efficient grounding system with low resistance, and keeping an appropriate distance between the external LPS and the PV system.

Can a PV mounting system carry a lightning current?

The metal components of the PV mounting system must be connected to the external lightning protection system in such a way that they can carry lightning currents (cop-per conductor with a cross-section of at least 16 mm2 or equivalent).

Do rooftop photovoltaic systems need a lightning protection system?

This guideline also requires that LPL III and thus a lightning protection system accord-ing to class of LPS III be installed for rooftop PV systems (> 10 kWp) and that surge protection measures be taken. As a general rule, rooftop photovoltaic systems must not interfere with the existing lightning pro-tection measures.

How does Lightning affect a PV system?

After studying the influences of lightning strikes on the PV system and modeling methods, it is mandatory to design a protection system for the PV system during lightning. The lightning protection system (LPS) is used to protect the PV system from damage and service interruption.

How to protect against lightning overvoltages?

The accurate analysis of lightning transients helps in selecting an effective and economic protection system. Moreover, the metal oxide surge arrester and the static synchronous compensator (STATCOM) were used to mitigate the lightning overvoltages [ 118 ].

Why is a mounting system connected to an external lightning protection system?

If the mounting system is directly connected to the external lightning protection system due to the fact that the separa-tion distance s cannot be maintained, these conductors be-come part of the lightning equipotential bonding system. Consequently, these elements must be capable of carrying lightning currents.
