Solar Panel Cleaning FAQs
If you have invested in solar panels, you will undoubtedly want to protect your investment by keeping them in good condition. But how can you maintain your solar panels and ensure they continue to run at maximum efficiency? Regular solar panel cleaning is crucial!
At Sydney Gutter Clean, we bring over 25 years of expertise in gutter maintenance and solar panel cleaning. Whether you need a dedicated solar panel cleaning service or prefer to combine it with gutter cleaning, we’re here to help!
In this FAQ guide, we’ll address the most common questions we get about solar panel cleaning—from how often they need to be cleaned to the tools and techniques recommended for optimal maintenance! Whether you’re considering a DIY approach or hiring our professional solar panel cleaning services, this guide will give you the knowledge you need to care for your solar panels correctly.
Do I Really Need To Clean My Solar Panels?
Yes!
Cleaning your solar panels is key if you want to protect your investment, and there are many benefits to doing so.
Over weeks and months, lots of dirt can build up on your solar panels. Regular PV solar panel cleaning helps improve the energy efficiency of your solar panels by cleaning away the dirt and debris that reduces energy absorption! It also prevents the lifespan of your solar panels by preventing long-term damage from stains and corrosion.
Solar panels are a significant investment, and cleaning them properly helps maximise your Return on Investment (ROI).
How Often Do Solar Panels Need Cleaning?
How often your solar panels need cleaning will depend on where you live, the climate, and the environmental conditions.
It is usually recommended to clean your panels every 6 to 12 months if you want them to perform optimally!
But if you live in a very dusty area, near construction sites, or your property has a lot of bird activity or pollen, more frequent cleanings could be needed. If your home or business is located near the coast, you may also experience salt buildup, which can reduce efficiency over time, so your panels will need extra care and attention!
Seasonal factors can also influence how often your solar panels need cleaning. For example, after the spring months, when there is a lot of pollen or following a dust storm or wildfire, your panels may require immediate attention. It’s wise to keep an eye on your solar panels over the year and look out for signs like reduced energy production or visible dirt buildup. You can rely on Sydney Gutter Clean any time of the year for effective and professional solar panel cleaning!
What Happens If Solar Panels Are Not Regularly Cleaned?
If your solar panels are not cleaned regularly, their energy production can be seriously affected.
Dirty solar panels can experience efficiency losses of up to 25%, and in extreme cases, such as areas prone to dust storms, efficiency losses can reach up to 30%.
Bird droppings, in particular, can cause "hot spots" that damage solar cells if they are not cleaned. Industrial pollution and pollen can lead to permanent staining, which reduces efficiency even more over time. Neglecting solar panel maintenance not only impacts performance but can even void manufacturer warranties if cleaning requirements are specified, leading to costly repairs and decreased ROI. Regular solar panel cleaning is the easiest way to avoid these issues and ensure your solar panels work efficiently for as long as possible!
Does The Rain Clean My Solar Panels?
Many solar panel owners mistakenly believe that rainwater is enough to wash away dirt from their panels, but this is not the case! A study by the National Renewable Energy Laboratory (NREL) showed that while rain can wash away some dirt, it is not enough to wash off stubborn dirt or pollen from solar panels! Rainwater also contains minerals, especially in hard water areas, which can leave behind residue or water spots as it dries.
So, if you want to make sure your solar panels are correctly cleaned and continue to work efficiently, it’s best to have them regularly cleaned. Call our Sydney solar panel cleaning team today on for a free quote!
Does Solar Panel Cleaning Affect My Warranty?
Yes, solar panel cleaning can impact your warranty! Many manufacturers specify that panels must be maintained according to their guidelines, which usually include routine cleaning to prevent performance problems.
So, if you don’t properly clean your panels, this can completely void your warranty if damage happens due to neglect, such as permanent stains or hotspots caused by debris.
DIY cleaning that results in scratches or damage from improper tools or harsh chemicals can also invalidate your warranty! If you want to stay compliant and keep your warranty intact, it’s best to document professional solar panel cleanings, as this demonstrates that maintenance was performed according to industry standards.
At Sydney Gutter Clean, we offer solar panel cleaning that complies with Workplace Health and Safety (WHS) legislation and the NSW Building Code. We will provide you with complete documentation, including invoices and even before-and-after photos!
How Much Does Professional Solar Panel Cleaning Cost?
In Sydney, the cost of professional solar panel cleaning by most providers typically ranges from $150 to $300, depending on the number of panels, the accessibility of your roof, and the level of buildup on them. If you research online, you will see that the average cost for standard residential systems (around 20 panels) is approximately $180 to $250.

Are There Eco-Friendly Solar Panel Cleaning Options?
Yes, eco-friendly solar panel cleaning options are available and highly recommended! Professional services usually use deionised water systems, which clean panels without the need for chemicals and leave a streak-free finish. Biodegradable and non-toxic cleaning solutions can also be used to remove grime and bird droppings safely without harming our local ecosystems. These methods reduce water waste and prevent harmful runoff. Eco-friendly tools, like soft-bristled brushes and microfiber pads, ensure a gentle yet effective clean.
What Tools Are Needed For Solar Panel Cleaning?
Non-abrasive tools are needed to clean the solar panel properly and avoid damaging the surface. Essential tools include a soft-bristled brush or microfiber sponge, a garden hose with a gentle spray nozzle, and a biodegradable soap or specialised solar panel cleaner. For stubborn grime, extension poles with soft cleaning pads help reach higher panels safely. Avoid using high-pressure washers, abrasive scrubbers or harsh chemicals, as these can scratch or degrade the panel's coating. Professional solar panel cleaners use deionised water systems, which leave a streak-free finish without mineral residue.
Should I Clean My Solar Panels Myself?
It is possible to clean your solar panels yourself, but before doing so, you must consider the pros and cons.
DIY cleaning can save you money, but climbing onto your roof can be dangerous. Using the wrong tools, such as abrasive brushes or high-pressure washers, can scratch or damage your panels, which could even void your warranty!
DIY methods can also leave streaks and residue, reducing the effectiveness of your solar panels. If you don’t have the tools, experience, or height safety training to clean your panels, professional solar panel cleaning is recommended. This results in a safer, more thorough clean using specialised equipment that prevents spotting and maintains your panels' maximum energy output.
