Dirty solar panels can reduce energy production by up to 5%. A good cleaning will restore lost performance.
A simple washing solution of water and a soft brush will do the trick. It is best to avoid high-pressure cleaning, as this can damage the solar panel surface and void warranty. Contact Solar Panel Cleaning Austin now!
While cleaning solar panels is relatively easy for the pros, it’s important to remember that you are dealing with electricity and working at an elevated height. As such, it is important to adhere to all relevant local and state safety regulations when performing solar panel maintenance on your own.
For the DIY homeowner, this means finding a safe spot to stand and using a non-abrasive sponge or cloth soaked in soap solution to clean the surfaces of your solar panels. Make sure to use minimal pressure and rinse thoroughly to avoid scratching or damaging the surface of your solar panels. After rinsing, use a squeegee or soft cloth to dry the solar panel surface. This step is crucial to preventing water spots and streaks, ensuring a clean and shiny finish for your solar panels.
A visual inspection of your solar panels can help determine if they are in need of a thorough cleaning. Dirty solar panels can reduce their efficiency by obstructing sunlight and can also appear discolored over time. If you notice any dirt build-up or any obstructive debris, it’s best to call a professional for a comprehensive cleaning and to ensure that your solar panels are properly cleaned to maximize energy production.
The most common causes of dirty solar panels include airborne pollutants and solid debris, such as bird droppings and wet leaves. Airborne pollutants typically wash away with the rain, but they can become more problematic if they form heavy or dense deposits on your solar panels. Localized soiling can also occur when large particles like bird droppings or wet leaves block specific parts of your solar panel system, whereas general soiling occurs when dirt and dust covers the entire surface of your panels.
Another major cause of dirty solar panels is the improper use of cleaning tools and equipment. Abrasive materials or chemicals can damage your solar panels, while abrasive brushes can scratch the surface and leave streaks. Using the wrong tool can also void your solar panel warranty and lead to damage, so it’s always best to work with a professional who is familiar with the proper tools for safely cleaning rooftop solar panels.
Cleaning Tools
The main goal when cleaning solar panels is to remove any dirt and debris that is hindering their performance. Using water and non-abrasive materials is the best way to do this without risking any damage or leaving behind residue. If abrasive cleaners are used, this can erode or damage the solar panel glass. For this reason, non-abrasive sponges and cloths should be used for cleaning solar panels instead of metal scouring pads or scrapers.
Depending on the type of solar panel system and location, different cleaning tools may be needed. Generally speaking, a solar panel cleaning kit should include a brush, non-abrasive cleaner, and a squeegee. While some people may be tempted to use a pressure washer, this is usually not recommended as it can cause scratches or other damage to the solar panels.
Solar panel cleaning brushes are designed specifically to remove dirt from solar panels without scratching the surface. They typically feature a telescoping pole with a brush at one end and an easy-grip handle at the other. Some brushes also feature a built-in squeegee to ensure the solar panels are dried thoroughly after being washed.
Some of the best solar panel cleaning brushes are made with microfiber cloths that are highly absorbent, allowing for fast and thorough drying. This helps to prevent streaks and reduce the chance of mineral deposits. Some of the better brushes are even designed to be compatible with hoses and outdoor faucets, making it easy to wash away any remaining debris on your rooftop solar panels.
Most solar panel manufacturers recommend only using approved cleaning solutions to avoid any potential damage or voiding of the warranty. A mild soap and water solution is ideal as it is safe for solar panels and the environment. In addition, it is a more environmentally friendly option than chemical-based products.
While a good rain shower can help with the cleaning job, it is not as effective as cleaning solar panels on a regular basis. This will prevent a build-up of ash and soot, which can drastically affect the panels’ performance.
Cleaning Methods
Using the proper cleaning methods is key to ensuring that your solar panels are not only clean, but also safe to use. Harsh chemicals and abrasive materials may damage the surface of solar panels, reducing their efficiency and life expectancy. Using non-abrasive cleaners and soft brushes, you can ensure that your panels are not only free of dust, bird droppings, and other debris, but that you can do so without risking their safety and integrity.
Depending on local environmental conditions, the frequency of cleaning may vary, but most experts recommend that solar panel owners clean their panels every 2-4 months in order to maintain peak efficiency. In some locations, frequent dust storms or high pollen levels may necessitate more frequent cleaning, while areas near highways, construction sites, or coastal areas prone to marine layer residue might require more extensive cleaning.
In addition to a ladder, a water hose with a moderate pressure setting, and a bucket of filtered (or distilled) water (to avoid mineral buildup), you will need a soft-bristled brush or a non-abrasive sponge. Dip the sponge into the bucket of filtered water, and then begin gently cleaning the surface of your solar panels to remove any loose dirt or debris.
After scrubbing, be sure to rinse the panels thoroughly with filtered water to prevent soap residue from clinging and potentially damaging the panel surface. Once the panels are completely dry, be sure to turn on your solar system and monitor them to ensure that they are functioning as expected.
If you are not comfortable climbing on your roof or don’t have the necessary equipment, it is recommended that you contact a solar power professional to complete the cleaning for you. They can provide the proper safety gear and ladders needed to access your solar panels, as well as a professional-grade cleaner that will safely and effectively restore them to their optimal state. They will also be able to perform a comprehensive inspection of the panels from the ground to check for any signs of damage or issues that may require further attention.
Cleaning Schedule
The frequency of solar panel cleaning can vary, depending on the location and type of build-up. Homes located near major highways or industrial areas may need to clean their panels more frequently, as pollutants can settle on the surface of the panels and decrease energy production over time.
Other factors that influence the need for cleaning include local climate conditions. Desert regions tend to experience higher dust accumulation rates, while coastal homes can be prone to salt spray and humidity that affects the surface of the panels. In addition, the installation angle of a solar system will also affect how often it needs to be cleaned. Steeper panel angles can reduce dust accumulation, while lower-angle systems are more prone to dirt and pollen build-up.
The most obvious indicator that solar panels require cleaning is a visible layer of dirt or debris. Inspecting the panels regularly will allow homeowners to quickly recognize when a cleaning is required. If there is a steep drop in power output, or the panels are visibly covered in dust or bird droppings, it’s likely time for a cleaning.
Before beginning a cleaning, make sure the solar panel system is turned off to avoid potential electrical shock. It’s also a good idea to disconnect any wires or cables to prevent damage while cleaning the panels.
Cleaning solar panels is an effective way to remove built-up debris and maintain optimal performance. When performed correctly, it can be done safely by a homeowner who has access to the right equipment and knowledge. However, if a homeowner is uncomfortable with climbing up on the roof or handling cleaning materials, it is best to contact a professional solar panel cleaner to perform the task.
Solar panel cleaning is relatively quick, inexpensive and easy to complete, making it a wise investment for any home that uses renewable energy. By keeping the panels in prime condition, homeowners can expect to reap the benefits of maximum energy production for many years to come.
