A Comprehensive Guide on Solar Panel Cleaning

Optimal performance of solar panels is directly linked to their cleanliness. Over time, dust, dirt, leaves, and bird droppings can accumulate on the surface of your panels, hindering their capacity to absorb sunlight and convert it into energy. This is where solar panel cleaning comes into play.

In this guide, we will break down the process of cleaning solar panels, offering insights into effective maintenance practices that will help ensure maximum energy output. Remember, a clean solar panel is a happy and efficient solar panel.

Why Clean Solar Panels Matter

Solar panels are designed to absorb sunlight. The panels are equipped with photovoltaic cells that convert solar energy into electrical energy, which can then power your home. However, any obstruction on the panel surface can impact its ability to function efficiently.

Over time, grime and dust can build up on the panels. In addition, bird droppings and leaves can also cause shadows on the surface, affecting the amount of sunlight the panels can absorb. A decrease in light absorption can result in a drop in energy production. Therefore, cleaning solar panels is crucial to maintain their efficiency.

Frequency of Cleaning Solar Panels in Gold Coast, Australia 

In the sunny climate of Gold Coast, Australia, solar panels can often get dirty more quickly due to increased dust and occasional bird droppings. As a rule of thumb, you should inspect your solar panels at least once a month to assess the level of dust and grime build-up.

The Gold Coast sees an average rainfall of around 10 days per month throughout the year, with the summer months being the wettest. This natural rainfall can assist in cleaning your solar panels; however, it may not be enough to thoroughly remove accumulated dirt and debris. Therefore, a more intensive cleaning might be necessary approximately 2-4 times a year, or whenever you notice a significant reduction in your solar system’s efficiency.

Please keep in mind that this frequency could vary based on specific environmental factors, the tilt of your panels, and the presence of overhanging trees or birds.

DIY: Steps to Clean Solar Panels in Gold Coast, Australia 

Cleaning solar panels is not a complicated task and can often be done without the need for professional help. Here are some simple steps you can follow to clean your solar panels:

  • Safety first: Ensure that you can access your solar panels safely. If your panels are mounted on the roof, use a ladder with a safety harness, and always have someone spot you. If you cannot safely access your panels, consider hiring a professional service.
  • Determine the best time: The ideal time for solar panel cleaning is either early in the morning or late in the afternoon when the panels are not too hot. A cooler temperature helps prevent water from evaporating quickly and leaving marks on the panels.
  • Prepare your cleaning tools: You don’t need any special tools to clean your solar panels. A hose with a suitable nozzle, a bucket of water, and a squeegee or a soft cloth will do the job. Remember, do not use any abrasive tools or harsh chemicals, as these can damage the panels.
  • Start cleaning: Rinse the solar panels with water to remove loose dirt and dust. Next, use the squeegee or soft cloth dipped in the soapy water to gently wipe the surface of the panels. Always clean from the top downwards.
  • Rinse and dry: After cleaning, rinse the panels again with clean water to remove any soapy residue. Avoid letting the water dry on the panels as this can leave water marks.
  • Inspect the panels: While cleaning, it’s a good idea to inspect the panels for any potential damage. If you see cracks, chips, or any other signs of damage, contact a professional for further assessment.

Hiring a Professional Solar Panel Cleaning Service

While cleaning gold coast solar panels can be a simple DIY task, there are circumstances when hiring a professional service is the safest and most effective option. Professional cleaners are equipped with the necessary tools, safety gear, and expertise to clean the panels thoroughly and efficiently.

Professional solar panel cleaning services are particularly beneficial if your panels are mounted high on the roof or in difficult-to-reach areas. They also come in handy if there’s stubborn grime that’s hard to remove or when you simply don’t have the time for a DIY cleaning.

Safety Tips 

Whether you decide to clean your solar panels yourself or hire a professional, safety should always be your number one priority. Here are some safety tips to consider:

  • Avoid Climbing on the Roof: If possible, clean your solar panels from the ground using a long-handled tool. If you must climb the roof, use a secure ladder and safety equipment, like a harness.
  • Avoid Wet Conditions: It’s important not to clean your solar panels when it’s raining or when the roof is wet. A wet roof can be slippery and dangerous.
  • Do Not Use High Pressure Water: High pressure water can damage the solar panels. It’s best to use a regular hose with a suitable nozzle.
  • Turn off the Solar Panel System: Before cleaning, ensure that the system is turned off. This is a recommended safety measure to prevent any electrical incidents.
  • Consult the Manufacturer’s Cleaning Instructions: Different solar panels may require different cleaning methods. Always consult the manual or manufacturer’s instructions before cleaning.


Keeping your solar panels clean is an essential aspect of solar panel maintenance. It not only prolongs the life of your panels but also ensures they operate at optimal efficiency. Regular cleaning can lead to better solar power output and, in turn, more significant savings on your energy bills.

Remember, if your panels are hard to reach, or if you’re unsure about how to clean them properly, it’s best to hire a professional solar panel cleaning service. Happy cleaning!
