6 FAQs about [Photovoltaic bracket lightning protection network]

How to reduce Lightning transient effects on PV system?

To reduce the lightning transient effects on the PV system, some protection measurements were proposed, including the grounding of the metal parts, providing external lightning protection such as the air termination rod, or using SPDs . The lightning effects on a large-scale PV plant with the existence of LPS was studied before [

Do lightning transient effects affect PV arrays during lightning strike?

The lightning transient effects on PV arrays are studied based on the system modeling to assess the recommended LPS designs studied in the literature. The paper also gives some recommendations about the modeling methods and protection of PV systems during lightning strike. 1. Introduction

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 ].

What is lightning induced voltage in a photovoltaic system?

Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.

Are lightning protection systems effective?

Experience shows that where lightning protection systems are installed, more often than not their design is poor and the protection they provide, ineffective. The problem becomes more serious for the industry, as the number of photovoltaic power plants increases.

Does a photovoltaic system need a discreet protection device?

When located outside the existing zone of protection on a building (see electro-geometrical pattern), a photovoltaic system needs a discreet protection device to protect it against lightning strikes. Two common situations are described in Figure 1.
