With Energy Matters, you can be sure you’re getting the best deal on solar energy. We only work with reputable solar companies with a proven track record of delivering high quality solar systems.

Regular cleaning of solar panels is essential to ensure their optimal performance. Cleaning frequency is affected by several factors, including location, weather conditions, and environmental contaminants.

Although heavy rainfall can occasionally clear dust and debris, studies show that dust accumulation can quickly reduce efficiency to 5% or less. Properly maintained panels can produce 3.5% more energy, while untreated panels can lose up to 30% in efficiency.

Dust is not the only culprit; leaves can also block sunlight, affecting the panel’s performance. Solar systems in dust-prone areas, such as near roads or farms, require frequent cleaning.

Neglecting to clean the panels in these areas can have a significant impact on energy production. Studies show that dust can reduce efficiency by up to 40% in such an environment.

Bird droppings can affect panel performance to a greater extent than dust accumulation. A common string inverter PV solar system can result in minimal or no energy production if bird droppings cover only part or all of a single solar panel. The affected panel/s of the micro-inverter solar system may experience no or limited power. You can read more about string and micro-inverters here.

Trees near your panels not only drop leaves and branches, but also attract birds. They create bird droppings and debris over time, which not only requires cleaning and maintenance, but also poses a safety hazard. Thus, monthly or annual gutter cleaning and bird checks may be necessary.

Another consideration to ensure your panels perform at their best is angle. Flat arrays will require more maintenance as they can leave mud deposits as water collects and evaporates. On the other hand, right angle arrays can use the rain without mud residue. This is because rain easily slides over them, protecting them from dust and pollutants.

Australia has more than 3.6 million rooftop solar systems as of September 2023. Australia’s clean energy transition continued in 2022, with renewables accounting for 35.9% of total electricity generation, a steady increase from 2021, according to the Clean Energy Council. This represents a significant increase since 2017, when renewables made up just 16.9% of the mix.

Remember to follow safety rules when using this approach to safely clean your sun and gutters. Read this article to learn more about how to clean solar panels effectively and safely.

While many homeowners prefer to stick to a tight budget and take a DIY approach, solar panel cleaning services provide professional service while adhering to industry safety protocols. Cleaning the panels is not as simple as it seems.

A little dust buildup may not be a big problem and can be handled with a garden hose. If your solar panels are very dirty or you are uncomfortable cleaning them yourself, it is best to seek help from a professional solar panel cleaner.

Cleaning Solar Panels: Maintenance Dos And Don’ts

Cleaning professionals or solar panel cleaners can take care of the tough problems and ensure that you are free from any danger associated with going out on your home. Coordinating with professionals will guarantee you the best cleaning standards.

Most DIYers use materials they already have around the house. If you prefer to clean your solar panels by hand, which is the best way to clean your solar panels, we recommend that you use clean water, detergent and a quality soft brush when using soapy water. If some parts of the panels need additional cleaning, use a mild detergent. Wipe soiled areas safely and thoroughly with mild detergent and a sponge covered with a soft cloth. This prevents harsh chemicals from marking your clean solar panels. Follow safety precautions when cleaning solar panels on your home.

You can always do the job with solar panel equipment such as a brush, rotating solar brushes and a water hose. You can use these tools while standing at the same ground level. However, in some cases, it is necessary to climb the roof to get the job done. We also recommend using a special solar panel cleaning solution for best results.

Needless to say, safety precautions must be followed when performing this difficult cleaning task. Always use seat belts to avoid falling to the floor – this method is used by professional cleaners. Don’t forget to wear a hard hat while performing this task. Always keep these tips in mind when cleaning your solar panels yourself.

Do Solar Panels Need To Be Cleaned?

While DIY ideas and professional services can help keep your panels clean and maintained, the solar industry is also providing new ideas for ongoing maintenance. These considerations include:

Kipp & Zonen’s DustIQ monitor system uses an LED and photodiode to monitor pollution in a solar array. This tool helps solar farm operators determine the ideal time to clean the arrays for optimal performance.

Industry experts recommend cleaning your panels at least twice a year. This will keep your investment in top condition and performing as expected.

Not maintaining your panels properly can also mean wasted energy. Remember, wasted energy is wasted money.

Does cleaning solar panels make a difference? Yes, of course. Below is the percentage of energy production you could lose each quarter if you don’t maintain your panels properly.

Rain often helps wash away general dust from dirty solar panels, and professional solar panel cleaning may not be necessary in this case. However, living in a high pollution area can bring additional dirt and debris, requiring a professional solar panel cleaner or garden hose to effectively clean your panels.

If a lot of dirty water or stubborn dirt in the array requires you to go up on the roof, always follow safety precautions. Use proper safety equipment, including wearing a seat belt and a hard hat, when cleaning regularly.

Solar panel cleaning requires a clean sponge and mild detergent to effectively remove dirt. If cleaning your solar panels yourself requires serious maintenance, you can never go wrong leaving this task to the professionals.

You Can Make Your Own Solar Panels, And It’s Easier Than You’d Think

A mild soap and water solution is the best way to clean solar panels. You can use a soft sponge or cloth to apply the solution to the panels and then rinse them with clean water. Avoid harsh chemicals or abrasive materials as they can damage the panels.

If you live in an area with hard water, use distilled water to wash the panels. Hard water can leave mineral deposits on the panels, reducing their efficiency.

You should also avoid cleaning your panels on a hot day. The heat can dry the soap too quickly and leave streaks on the panels. It’s best to clean your panels on a cool, cloudy day.

Yes, turning off solar panels before cleaning them is essential to ensure safety and prevent electrical hazards. Solar panels generate electricity when exposed to sunlight, and even a small amount of residual current can pose a risk of electric shock. Shutting down the system eliminates this potential risk and ensures a safer cleaning process.

Yes, it is generally safe to hose off solar panels to remove dirt and debris. It is recommended that you do this regularly to ensure your panels are operating at peak efficiency. Rainwater will naturally clean your panels to some extent, but it’s not always enough to remove all build-up. Pulling the panels down helps remove any remaining dirt, dust, pollen or other contaminants.

The safety of using Windex on solar panels remains a debate among experts. It is always recommended to consult with your solar panel installer or manufacturer to determine the most appropriate cleaning method for your specific panels. Although Windex is generally considered safe for cleaning windows, care should be taken when using it on solar panels. Dilute Windex with water, don’t use it on hot or sunny panels, and don’t use ammonia-based Windex.
