How Often Should You Clean Your Solar Panels?

Solar panels are a smart investment—especially in sunny Busselton. But to keep them operating at peak efficiency, regular cleaning is a must. Dust, salt spray, bird droppings, and debris can all reduce the amount of sunlight your panels absorb, which means you’re not getting the energy savings you paid for.

In this blog post, we’ll answer the big question: How often should you clean your solar panels in Busselton? Plus, we’ll share why professional cleaning makes all the difference.

Why Clean Solar Panels Matter

Dirty solar panels don’t just look bad—they perform worse. Even a light layer of dust or grime can block sunlight, reducing your system’s efficiency by up to 20% or more. In coastal areas like Busselton, panels are also exposed to salt residue, which can cause long-term corrosion if not cleaned regularly.

Keeping your panels clean helps:

  • Maximise energy output
  • Extend the lifespan of your system
  • Protect your warranty (some warranties require regular maintenance)

So, How Often Should You Clean Them?

General Guideline: Every 6–12 months

For most homes in Busselton, a professional solar panel clean once or twice a year is ideal. However, this can vary depending on your location and environment.

Factors That May Require More Frequent Cleaning:

  • Near the coast – Salt spray can build up quickly
  • Under trees – Leaves, pollen, and bird droppings are common
  • In dry, dusty areas – Dust and dirt settle more often
  • Holiday homes – Long gaps between visits mean panels go unchecked

If your solar panels are exposed to any of these conditions, consider scheduling a clean every 4–6 months to ensure optimal performance.

DIY vs Professional Solar Panel Cleaning

While it’s possible to hose down panels from the ground, DIY cleaning rarely removes stubborn grime and often doesn’t provide even coverage. Worse, climbing onto a roof with cleaning tools can be dangerous without proper training and equipment.

At Modern Window Cleaning, we use pure water technology to gently but thoroughly clean your panels—chemical-free, streak-free, and safe for the surface. Our technicians clean from the ground using extendable poles, ensuring safety and efficiency without the risk of damage.

Signs Your Panels Need Cleaning

Not sure if it’s time? Look for:

  • Visible dust or bird droppings on the surface
  • Drop in power output (check your inverter or monitoring app)
  • Water streaks or salt residue after rain or coastal winds
