A common mistake when cleaning solar panels is using a pressure washer.

Why not use a pressure washer?

• The powerful jet can cause micro-cracks in the glass surface.

• Water can penetrate through the seals, leading to short circuits or delamination.

• High pressure damages coatings that are essential for light transmittance.

Safe alternatives

Always use:

• Soft osmosis water

• Special soft brushes or professional cleaning services

Conclusion

Use never a pressure washer on solar panels; you risk serious damage.
