1) It is generally recommended to install lightning protection devices (such as lightning rods /
lightning protection belts and down conductors) to prevent lightning from hitting the PV array.
2) Lightning protection devices and down-conductors and related equipment in photovoltaic
systems (including photovoltaic panels, inverters, cables, power distribution equipment) should
maintain a safe separation distance S.
Suggested value of S: According to the general 5 storey height (about 15m) building roof, S
takes 2.5m enough, the distance S have relationship with the building height.
A. When the safety distance S is satisfied:
The position of the figure should be equipped with a lightning protection module. In general,
it is recommended to install Type II in position (l) and Type I in position ©.
B. When the safety and safety distance S is not met:
In addition to position 3, Type I lightning protection module should be installed in Figure
3) The lightning down conductor and the equipment ground wire eventually sink at a total
ground point, but the two cannot share the wire. That is, the equipment grounding wire should
be pulled separately, and the wire diameter requirement >6mm
2
when the safety interval dis-
tance S is satisfied.
