  • Using specialised solar panel cleaning equipment

Solar Panel Cleaning FAQs

Ideally, it would be best to have your Melbourne property’s solar panels cleaned twice a year (once every six months) to maintain their high efficiency. Since your goal is to maximise solar panels system’s output, lower energy bill, and safeguard your solar investment to reap long-term benefits, you can even consider having solar panels cleaned by experts once every four months – especially when considering other factors that can influence the frequency of cleaning, such as:

  • If there’s a noticeable drop in energy production, it could be a sign that the panels need cleaning
  • Angle of panels is important, as flat solar panels tend to accumulate more debris than tilted ones.
  • Melbourne’s unpredictable weather conditions (four seasons in one day) surely come into play
  • Panels near trees can accumulate tree sap or bird droppings, necessitating more frequent cleaning
  • Areas with high industrial pollution or construction activities might require more regular cleaning
  • Some solar panel manufacturers might have specific cleaning intervals to ensure optimal performance

Pro Tip For You: We genuinely believe in helping you get the most out of your investment. While it might be tempting to opt for DIY methods or skip solar panel cleaning for months to save a bit, it is important to remember that your solar system is a valuable asset.

Well, the time required for solar panel cleaning can vary based on several factors. On average, it takes approximately 1-2 hours to clean 10 solar panel modules. However, the duration can change depending on the following considerations:

  • Pre-inspection Time: Sometimes, a preliminary inspection is needed to assess the condition of the panels and devise a cleaning strategy.
  • Level of Dirt Accumulation: Solar panels with heavier dirt or debris accumulation may take longer to clean compared to those with minimal soiling.
  • Accessibility of Panels: Panels installed at challenging angles on the roof might require additional time for safe and thorough cleaning.
  • Presence of Persistent Stains: Marks like bird droppings, sap, or hard water stains might need specialized treatment, prolonging the cleaning time.
  • Frequency of Cleaning: Panels that are cleaned more regularly might be quicker to clean than those that have been neglected for longer durations.

These are some telltale signs that clearly suggest you need to call Mr Window Cleaning® for a comprehensive solar panel cleaning service:

  • Decreased Energy Output: One of the most obvious signs is when you start noticing a reduction in your solar panels’ efficiency or a drop in the energy they produce.
  • Visible Dirt and Debris: If you see layers of dust, bird droppings, or other debris on the surface of the panels, it’s time to consider a cleaning.
  • Moss, Mould, or Algae Growth: In humid conditions or shaded areas, moss, mould, or algae can grow on solar panels. This not only affects efficiency but can also damage the panels over time.
  • Water Staining: Over time, rain or hard water can leave stains on your solar panels, especially if they are tilted at a shallow angle. These stains can reduce the efficacy of the panels.
  • It’s Been Over A Year: If you haven’t had your panels cleaned in the last year, it’s recommended to have them checked and cleaned by a professional. Regular maintenance can prolong the life and efficiency of your panels AND save you lots of money!

Identifying the signs early on can prevent a decline in the efficiency of your solar panels and save on potential costs in the long run. Melbourne’s varied climate and environmental factors make regular solar panel cleaning essential.

Unfortunately, yes! When you clean the panels yourself, there’s a risk of causing scratches or other damages using improper tools or techniques. These damages can compromise the panel’s performance. Moreover, many leading solar panel manufacturers have a specific condition in their warranty: only professional cleaning will keep the warranty intact.

Therefore, if you choose the DIY route, you might inadvertently void the warranty. It’s crucial to consult your warranty terms before deciding on a cleaning method to ensure your panels remain protected. The best course of action would be to call the pros at Mr Window Cleaning® to do the job in a completely safe, mess-free, and affordable manner.

Absolutely not! Unlike some solar panel cleaning companies, we steer clear of using pressure washers for cleaning solar panels. The reason is straightforward: pressure washers can be incredibly forceful, potentially causing damage to the delicate surface of the solar panels. Any damage or even minor abrasions can compromise the panels’ performance and efficiency. Taking such risks with valuable equipment is not in our practice.

Instead, our preferred method is the Pure Water System. This system is not only highly effective at removing grime and dirt but is also gentle on the panels, ensuring their longevity.
