Dirty solar panels can produce significantly less energy than clean panels.

Average losses due to dirt

• Light dust and pollen: 2% to 5% loss

• Heavy soiling (bird droppings, sand): up to 20% loss

• In extreme cases even higher, depending on location and circumstances

Why dirt has such a big impact

Dirt blocks direct sunlight and causes uneven cell loading, which reduces efficiency.

Conclusion

Even light soiling can noticeably reduce efficiency. Regular cleaning pays off!
