Solar Lightning Protection System Installation
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 equipment and saf. 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.
