The good news is that solar panels don’t need to be washed as often as you might think. However, they do accumulate dirt and debris over time and may need to be cleaned from time to time.
The best way to clean your solar panels is with a garden hose. Avoid pressure washers as they can damage the panels. Instead, use a soft sponge and a little soap.
Debris Buildup
Generally, solar panels need no more than a quick hose-down once in a while. This is often enough to get rid of most of the dust and dirt that accumulates on them, even in places where it rains a lot. However, it is still a good idea to clean your solar panels at least once a year for optimal energy production and efficiency.
If you need to scrub off more serious forms of debris, such as bird droppings or plant sap, then it is a good idea to use a soft brush and water in conjunction with some mild soap. This can be done safely on a roof or ground and will not damage your solar panels in any way.
The key is to be gentle, as any abrasion will cause the materials to wear out sooner. It is also important to choose a cleaning tool that is safe for your panels. Avoid using anything too harsh, such as a leaf blower, as this could scratch them.
Another type of debris that can build up on a solar system installation is pollen, which is usually released by flowers and trees. This is typically swept away by wind and rain, but if it builds up on the panels, it can reduce the amount of sunlight that they absorb and generate electricity.
In general, though, the best time to wash your solar panels is during cool weather and not when it’s hot outside. This can prevent the water from evaporating before you can wipe it off, which can leave a smear or residue that can decrease your panel’s efficiency.
It’s a good idea to mix the soap with warm water so that it doesn’t dry on the panels as quickly. You should also avoid using cold water, as this can also damage the glass of your panels.
Once you’ve mixed the soap with the water, you can spray it down on the panels to loosen any buildup or debris. If necessary, you can also use a brush or squeegee to remove any excess.
Then, simply rinse the solar panels with clean water and let them air dry. Afterward, you can put them back up on your roof, if you wish. Hopefully, you won’t need to do this again, but it is always a good idea to check them regularly for any signs of buildup or debris.

Dirty Roof
A dirty roof can make a big difference to the overall look and feel of your home, and it can also impact your property value. In some cases, it can even lead to a decrease in the efficiency of your solar panels.
The amount of time that you need to clean your panels will depend on the climate where you live and how much dust is present. If you live in a desert region, for example, more frequent cleaning is recommended as sand and dust can reduce a solar panel’s performance by up to 40%.
Typically, you will need to clean your solar panels on a weekly or monthly basis. However, this varies from home to home and from panel to panel.
- Step 1: Dislodge any dirt or debris from your solar panels by using a soft brush and water. You may need to use a spray bottle or hose wand for this, depending on the size of your solar system.
- STEP 2: Wash your solar panels with water and soap, such as regular dish soap. This will ensure that you are not using any harsh chemicals, which can damage your solar panels and make them less efficient in the long run.
Once you have cleaned your solar panels, rinse them with water again to remove any soap residue. You can use a squeegee or a chamois to wipe them dry to avoid leaving any residue behind.
This process will take a little bit of time, so you should plan ahead. In some cases, it can be a good idea to contact a local professional that specializes in cleaning solar panels.
You can find these professionals by doing a search on the internet for solar power companies near you. They will be able to offer you free, no-commitment estimates for cleaning your solar panels.
If your solar panel has a monitoring tool, it will tell you when it is time for you to clean it. Generally speaking, you should clean your solar panels as soon as possible after you see signs of dust or other contaminants.
Decreased Power
The efficiency of solar panels can be reduced by dust, pollen, and debris. These materials block sunlight from reaching the photovoltaic cells, reducing the power production and cost of the system. Similarly, water droplets from the rain and moisture from bird droppings or leaves also reduce the panel’s ability to collect energy from the sun.
Even when it’s sunny outside, it’s important to clean your solar panels regularly. Not only does this keep your panels in good working condition, but it can increase your energy output and lower your electric bill as well.
Cleaning is recommended once or twice a year depending on your climate and where you live. If you live in a particularly dusty or dirty area, it may be necessary to clean more often.
A study examining solar panel performance before and after a simple rag and water cleaning found an average 3.5% boost in energy production from the cleaned panels. However, a heavy rain shower also worked to clean the dirt but didn’t increase performance as much.
This is because dirt and debris can be cemented on the surface of a PV panel. This occurs when the dust cools off at night and then dries in the morning, making it difficult to remove with water alone.
Researchers at MIT have developed a new, water-free system to clear dust from solar panels. This technology could reduce the operating costs of solar installations and improve their overall performance by eliminating the need for trucked-in water, explains Miriam Fauzia at The Daily Beast.
Many large solar power installations are located in desert regions, where the water used to clean the panels must be trucked in from a great distance. This means the water has to be pure to avoid leaving deposits on the surfaces.
In addition, the dry scrubbing technique often used to clean these panels is less effective at removing particles and can damage the surfaces. The new system uses static electricity to clear the dust, lowering the operating cost and improving the performance of the solar panels.
Dirty Gutters
If you own a home that has solar panels, you know that they require regular cleaning to keep them performing optimally. Dirt, dust, pollen mold, and bird droppings are a few of the biggest contributors to lower panel efficiency and reduced output.
Thankfully, a professional solar panel cleaning company can help you take care of all of these issues without damaging your investment or creating hot spots that can nullify your warranty.
You should try to clean your solar panels every couple of years. However, this can be hard to do when you are juggling work and other commitments. This is why you should call a professional for a thorough job that will get your panels looking as good as new.
One of the best times to clean your solar panels is in the morning. This is because the dew that accumulates on the panels overnight will soften the dirt and grime, making it easier to wipe off.
Another great time to clean your solar panels is when the sun is out. The UV rays that the sun provides to your panels will help them function at their highest performance level. This is also a good time to see how much power your panels are generating.
While the sun is shining, you can try using a hose with a high-powered nozzle to spray your panels. Make sure you direct the water to the top of your solar panels and not to the back or sides as this will affect their efficiency. You can also use a garden hose with a nozzle attachment to squeegee the dirt off the front of your solar panels. This will make your cleaning job much easier and more effective.
In addition, you can also use a squeegee to remove the residue that falls on your roof after it rains. This can help your gutters keep the rain out, avoiding problems like ice dams in the winter and damaged brickwork from dampness.
A professional solar panel cleaning company will have the proper equipment and expertise to get the job done right. They should arrive on time, provide accurate estimates and follow through on all of their promises. Additionally, they should have the right insurance coverage so that they don’t have to worry about any damage occurring during their work.
