5.8 GROUNDING AND LIGHTNING PROTECTION
Lightning can damage solar pump systems if the following precautions are not taken. A proper
connection to ground (earth) is important as it allows static electricity to discharge to earth—helping
to prevent the attraction of lightning. In case of a nearby lightning strike, a well-grounded solar array
support structure provides a path to conduct an induced surge of current around the electrical
circuitry, preventing damage in most cases.
