For most homes, rain keeps panels remarkably clean, and the cost of professional cleaning often exceeds any recovered production. Occasional inspection beats frequent cleaning.

When cleaning actually helps

  • Heavy dust or pollen is visibly reducing output
  • Bird droppings accumulate under roosting areas
  • Soft, frequent rainfall isn’t clearing debris

What to inspect annually

Check your monitoring for unexpected drops, look at panel condition, and confirm inverters and mounts are sound. Simple, infrequent checks catch most problems early.
