How Often Should You Clean Your Solar Panels?

Most experts recommend cleaning your solar panels every 6 months. However, this depends on several factors:

  • Location – If you live in a dusty or high-pollen area, more frequent cleaning is needed.
  • Weather Conditions – Areas with heavy rain naturally clean panels, but in dry climates, dirt builds up faster.
  • Nearby Trees – Leaves, bird droppings, and pollen can reduce solar panel performance.
  • Angle of Panels – Flat panels accumulate more debris than tilted ones.

🔹 General Rule:

  • Urban areas: Every 6–12 months
  • Dusty, rural, or high-pollen areas: Every 3–6 months
  • Near trees or bird activity: Every 3 months

Signs Your Solar Panels Need Cleaning

Not sure when to clean? Watch for these signs: ✅ Noticeable Drop in Energy Output – If your solar production drops, dirt could be the cause.
✅ Visible Dust, Dirt, or Bird Droppings – A quick look at your panels can tell you if they need cleaning.
✅ Water Streaks or Hard Water Deposits – After rain, water spots may form, reducing efficiency.

DIY Cleaning Tips

If your panels are easy to access, you can clean them yourself:

  • Use a soft brush or sponge with mild soap and water.
  • Avoid harsh chemicals or pressure washers that can damage the panels.
  • Clean early in the morning or late afternoon to prevent streaks.
