6 FAQs about [Rooftop photovoltaic panel lightning protection test report]

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.

Does a PV rooftop have a lightning surge test?

There is no circuit model or test for the PV Rooftop system dedicated to lightning surge studies, especially in aspects of SPD placement, selection of suitable ratings, cable length, and sizing, and number of SPDs required. Direct strikes may trigger fires and even explosions to the PV Rooftop installation.

Why is a sensitivity analysis necessary in a rooftop PV system?

A sensitivity analysis is necessary for the development of lightning overvoltage in a Rooftop PV system, bearing in mind the impact of lightning striking spot, the lightning current ampli-tude, the building height, the soil resistivity and the distance between the solar arrays and the external protection system.

Can Lightning affect a roof top PV system?

It has been shown that for buildings with roof top PV systems only the avoidance of lightning attachment to unprotected parts of the building is not sufficient. Lightning currents passing through the lightning protection system may still affect the PV power system through inductive coupling.

Can a PV rooftop system withstand lightning strikes in Malaysia?

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.
