Top 5 Solar Panel Cleaning Solutions
Thanks to an effective solar panel system, it has been incredibly fulfilling since you made the decision to go green and save money while maintaining an energy-efficient home. Consequently, over a period of time, you begin to notice the energy produced is not as efficient as it used to be. This could be due to many reasons, among which are dirt and grime.
Clean solar panels are essential for maintaining optimal energy output and ensuring the long-term success of your solar investment. Solar panel cleaning is often overlooked, but dirty panels can significantly reduce efficiency and energy generation.
In this guide, we’ll reveal why cleaning your solar panels is important, when to clean them, the top 5 solar panel cleaning solutions available, and when it’s best to call in the professionals.
Why do solar panels need cleaning?
Solar panels are installed outdoors, where they are continuously exposed to various elements. Over time, dust, dirt, debris, and even bird droppings accumulate on the surface, creating a layer that blocks sunlight. This buildup reduces the efficiency of your panels, leading to lower energy output and increased electricity bills. Regularly cleaning your solar panels ensures that they can efficiently harness sunlight and generate the electricity your home needs.
Here in Australia, during the dry season, when there is less rain and snow but more dust, more cleaning is necessary. If your solar panels are installed in areas with deciduous trees, leaves from these trees can land on your panels, forming dirt and even attracting birds. So you may need to clean dirty solar panels frequently.
When should solar panels be cleaned?
Knowing when to clean your solar panels can help you improve their efficiency and prolong their lifespan. As a general rule, you should aim to clean your solar panels at least twice a year, but this depends on your location and environmental factors. If you notice a drop in energy output or see visible dirt and debris on the panels, it’s time to clean them. In areas with heavy dust or near industrial zones, your panels may require more frequent cleaning to maintain optimal performance.
Weather conditions play a significant role in determining the frequency of cleaning. Panels located in dry, dusty environments or regions with less rainfall are more prone to dirt buildup. Additionally, if your area experiences frequent bird activity, the panels may need cleaning more often. Periodic inspection of your solar panels will help you determine if dirt and debris are impacting their efficiency.
Top 5 solar panel cleaning solutions
When it comes to cleaning solar panels, it’s important to choose the right solution to avoid damage while effectively removing dirt. Below are some of the best cleaning solutions to maintain clean and efficient solar panels:
Rinsing with low-pressure water
A simple rinse with a hose using low-pressure water is often enough to clean your solar panels. Avoid high-pressure washers, as they can scratch or damage the panels. Use a mild solution of water and ensure they’re free of any abrasive residue.
Washing with soapy water
For stubborn dirt, grime, and debris, a solution of water and mild soap works well. Use a non-abrasive sponge or cloth to gently clean the panels. Avoid using abrasive materials that can scratch the surface. After scrubbing, thoroughly rinse the panels to remove any soap residue.
Professional servicing
Another way to maximise your solar panels is to get them serviced. If you prefer not to handle the cleaning yourself or if the panels are difficult to reach, hiring professional solar panel cleaning services is a smart choice. They have specialised equipment to ensure your panels are cleaned thoroughly without causing damage.
Using isopropyl alcohol for stubborn stains
Isopropyl alcohol is an effective cleaning solution for tough stains like bird droppings or sticky residue. Apply it sparingly, and use a soft cloth to gently clean the affected areas. Avoid using harsh chemical cleaners, as they can harm the panels.
Consider hydrophobic coating
Consider using Nanotech’s innovative solar panel hydrophobic cleaner. Installing a hydrophobic coating on your solar panels helps repel water, dirt, and debris, reducing the need for frequent cleaning. This solution can be especially beneficial in areas prone to heavy dust or bird activity, as it creates a barrier that keeps your panels cleaner for longer periods of time.
Nanotech solar panel cleaner is a high-technology self-cleansing product that offers longevity to your panels, keeping them clean for as long as 2 years, protecting your panels against mould, dirt, and grime without your efforts, and boosting your energy output by keeping your solar panels clean with just rainwater.
When should you call the professionals?
While DIY cleaning is an option, there are situations where professional cleaning is the best course of action. For instance, if your solar panels are installed on a steep roof or in hard-to-reach areas, attempting to clean them yourself could be risky. Additionally, if the panels have accumulated a thick layer of dirt or debris that requires specialised cleaning, we recommend getting professional help.
Professional solar panel cleaning services use industry-standard equipment and techniques to clean your panels safely and efficiently.
Moreover, professional cleaners can provide a comprehensive solar panel maintenance service, like applying a self-cleaning hydrophobic coating and inspecting the panels and related components for any signs of damage. This thorough approach not only keeps your solar system clean but also ensures longevity and sustained performance.

FAQs
How Often Should You Clean Your Solar Panels for Optimal Efficiency?
To maintain optimal efficiency, it’s recommended to clean your solar panels at least twice a year. However, factors like heavy dust, debris, and environmental conditions may require more frequent cleaning. In regions with excessive dirt buildup, panels may need to be cleaned quarterly or even monthly to avoid excess streaks and drops in clean energy production.
What Are the Best Methods for Cleaning Solar Panels?
When cleaning solar panels, start with a gentle manual rinse using a hose and a soft brush or squeegee. For tougher grime, use a mild soap and water solution. Avoid high-pressure washing or abrasive materials, which can damage the panels and leave streaks. Always follow the manufacturer’s guidelines to ensure your panels remain in top condition.
Do Dirty Solar Panels Reduce Energy Output?
Yes, dirty solar panels can significantly reduce energy output. Accumulations of dust, dirt, and debris create a layer that blocks sunlight, resulting in less clean energy being generated. Regular cleaning ensures that your panels can efficiently harness sunlight and operate without excess grime impacting performance.
How Can I Save on Solar Panel Maintenance with Frequent Cleaning?
Regular and frequent cleaning helps extend the lifespan of your solar panels, ensuring they remain in peak condition and generate maximum energy.
