How to Protect Solar PV Systems from Lightning

Direct lightning strikes pose the most immediate and severe threat to PV systems. When lightning strikes a solar panel or nearby structure, it can cause catastrophic damage, including: Damage to Components: The high-energy surge can destroy critical electronic components such as inverters, battery management systems, and connecting cables.

Choosing the Right DC SPD for Solar Applications

However, the reality is without surge protection, even the slightest voltage spike can damage every electronic device that draws power from the solar panel array. Additional to that, without lightning protection, any investment you make in energy efficiency will be useless, as lightning is one of the leading causes of solar panel failure.

Like all electrical devices, PV systems are also sensitive to overvoltages: components such as inverters, PV panels, battery storage systems, and cables can all suffer damage. Effective protection against overvoltages therefore increases the operational safety of the system and also provides security for the owner.

Solar Lightning and Lightning Protection

The frames and mounts on panels are usually grounded (sometimes more by accident than design), and that often diverts the lightning directly to ground, saving the panels. Also, the battery banks on most off-grid PV systems act as a fairly good surge arrestor if you have good connections and a good ground - but it may take out the controller on it''s way.

If it is greater than 10 metres, a second SPD is necessary and should be located in the box close to the solar panel, the first one is located in the inverter area. To be efficient, SPD connection cables to the L+ / L- network and between the SPD''s earth terminal block and ground busbar must be as short as possible – less than 2.5 metres (d1+d2<50 cm).
