Effects Of Lightning On Solar PV⚡

Added: 2026-05-16

[00:00:00]Here are some ways your solar plant can fail you in case of lightning.

[00:00:04]In many cases, lightning does not even need to hit your solar panels directly.

[00:00:08]When high search currents enter your DC string and exceed the diode limit, the bypass diodes fail and this causes hotspots to form in your solar panel, which reduces the module output over time. Surges can also travel through your DC cables and reach your sensitive components like damaging your inverter.

[00:00:25]When this happens, the inverter trips and the generation stops instantly. Even the module glass itself can develop micro cracks from rapid heating, which creates stress inside the glass.

[00:00:36]Moisture enters through these cracks and your module life starts reducing. This is just the beginning. Lightning can damage your solar plant in more ways if your protection isn't designed right.
