Solar power generation lightning protection system
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 safely discharges the surge into the earth. An electrical path to ground will constantly discharge static electricity. 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, noncorrosive.
