6 FAQs about [Photovoltaic inverter lightning protection level measures]

Do PV systems need lightning protection?

With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.

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 will a lightning protection system affect PV power generation?

All this kind of destruction will undoubtedly affect the economic aspects or the return on investment that could be earned from PV power generation as well as the cost of repair or replacement to recover from the damage, all of which can be mitigated by implementing a lightning protection system (LPS) .

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).

Why is lightning protection important for photovoltaic installations?

The lightning protection of photovoltaic installations is of great importance, in order to warrant the uninterrupted operation of the system and avoid faults and damages of the equipment. Atmospheric discharges influence the proper operation of the photovoltaic generators and their installation, involving also sensitive electronic equipment.

How to protect a PV system from lightning discharges?

In case that a PV installation is protected against lightning discharges by an external LPS, the above distance s between the PV equipment and the parts of the LPS should be respected, in order to avoid sharing of discharge currents through the metallic components of the PV system.
