Quick Answer
Lightning damage can manifest as burns, charring, or melting on solar panels, inverter components, or wiring. It may also cause electrical malfunctions or complete system failure. Careful inspection is necessary to identify potential lightning strikes.
Identifying Visual Signs of Lightning Damage
Inspect solar panels for burn marks, charring, or melted plastic, as well as discoloration or bubbles in the panel’s surface. Check inverter components for signs of electrical arcing, such as melted or carbonized areas, or blown fuses. Look for loose connections or damaged wiring, which can indicate a lightning strike. In some cases, lightning damage may cause a complete short circuit, resulting in a blown fuse or tripped circuit breaker.
Assessing System Performance
Monitor system performance after a lightning storm, paying attention to any unusual behavior or decreased efficiency. Solar panel output may be affected if the inverter or panel components have been damaged. Inverters may display error messages or warning lights, indicating a problem with the system. Check the inverter’s logs or data for any anomalies that may indicate lightning damage.
Mitigation and Repair
If lightning damage is suspected, disconnect the system from the grid and do not attempt to use it. Contact a qualified solar technician to assess and repair the damage. They will use specialized equipment, such as thermal imaging cameras, to detect any hidden damage. Repair will involve replacing damaged components, such as solar panels, inverters, or wiring, and verifying that the system is functioning correctly.
