Surge Protection for Photovoltaic Systems

The SPD that is provided on the dc output must have a dc MCOV equal to or greater than the maximum photovoltaic system voltage of the panel. When lightning strikes at point A (see Figure 1), the solar PV panel and the

Models of major components in the PV systems including structure steels, wiring in panels, and PV cells are provided. The non-linear surge protective device (SPD) is also considered in the modelling.

Overvoltage Surge Protection–Technical Note

It is not necessary for lightning to strike the PV site to damage it; therefore, it is worthwhile to consider all the ways in which lightning can induce surge, including electrostatic and magnetic

6 FAQs about [Photovoltaic panel lightning arrester]

What is a lightning arrestor?

Lightning (surge) arrestors are designed to absorb voltage spikes caused by electrical storms (or out-of-spec utility power), and effectively allow the surge to bypass power wiring and your equipment.

Can a PV system be installed on a building with a lightning protection system?

If the PV system is installed on a building with an existing lightning protection system, the PV system must also be properly included in the lightning protection system. The inverters are classified as having Type III (class D) protection (limited protection).

What is a pluggable type 1 lightning arrester?

The pluggable type 1 lightning arrester from the Safe Protection Plus product family provides reliable system protection for two-position, isolated DC voltage systems with 1,000 V DC. With an optimized design and pluggability, it features advantages for installation and maintenance.

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 PV systems vulnerable to lightning?

Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].

Can lightning cause a photovoltaic system failure?

Lightning can cause photovoltaic (PV) system failures as lightning that strikes the system from a great distance away, or even between clouds, can generate high-voltage surges.
