Lightning rarely hits solar panels directly, but nearby strikes can destroy inverters and controllers through induced voltage surges. Proper grounding, surge arrestors on both DC and AC sides, and surge capacitors reduce damage risk by over 95 percent in most installations. In solar photovoltaic power generation systems, the solar surge protective device (PV SPD, Photovoltaic Surge Protective Device) is a critical safety component specifically designed to protect electrical equipment from transient overvoltage damage. Proper surge protection is essential. Repairs are costly and may need full replacements. Its core function is to protect sensitive electronic equipment from transient overvoltages (surges) caused by lightning strikes, switching operations. Indirect Lightning Strikes Pose Greater Risk Than Direct Hits: While direct lightning strikes are rare, indirect strikes within several miles can induce dangerous voltages exceeding 4,000 volts in solar wiring.
