Grounding is the most fundamental technique for protection against lightning damage. You can't stop a lightning surge, but you can give it a direct path to ground that bypasses your valuable equipmen. The weakest aspect of many installations is the connection to the earth itself. After all, you can't just bolt a wire to the planet! Instead, you must bury or hammer a rod of conductive, nonc. For building wiring, the NEC requiresone side of a DC power system to be connected—or “bonded”—to ground. The AC portion of such a system must also be grounded in the c. Array wiring should use minimum lengths of wire tucked into the metal framework. Positive and negative wires should be of equal length and be run together whenever possible. This wil. In addition to extensive grounding measures, specialized surge protection devices, and (possibly) lightning rods are recommended for sites with any of the following conditio.
[PDF Version]So, to properly protect your solar panels from lightning damage, you should install specialized lightning protection for solar panels devices. This helps prevent electrical surges that can potentially destroy panels and other system components. 1. Surge Protectors Here we'll discuss Surge Protectors.
Figure 5 shows an appropriate integrated lightning protection system for a sample solar power system located on a building at roof level, while figure 6 depicts a free field solar panel farm equipped with a lightning protection system.

Lightning is a common cause of failures in photovoltaic (PV) and wind-electric systems. A damaging surge can occur from lightning that strikes a long distance from the system or between clouds. But most lightning damage is preventable. In this article, you will learn how to protect your solar power system from lightning.
The installation of an external lightning protection system has the mission of avoiding direct impacts on the structure, and therefore in this case on the photovoltaic panels installed on its roof.
