Based on all solar companies’ contracts it is up to the homeowner to maintain the cleanliness of your panels. You can do it yourself and risk injury or you can contact us to professionally clean them for you. We are trained and have a $2 million dollar liability insurance policy should anything out of the ordinary ever happen.

We can clean as many as 5000 panels daily due to our trademark process. No one else does what we do because we developed this process. We also currently clean more than 100,000 panels yearly in the Phoenix area.

How to Clean Solar Panels

There are several ways to clean solar panels. Depending on their location, they may collect more surface soiling than others. People who live in cities or downwind of an airport or farmland may accumulate large amounts of dust. In regions with sparse rainfall, you may need to clean your panels more frequently. Those who live in areas with high levels of pollution may also find that their panels have a hazy film. For these situations, you may need to clean your solar panels with a soft cloth. For this purpose, you can use an electric rolling brush or vehicle-mounted brush.

In the sun

Depending on where you live, you might find oily stains on your solar panel. If you live near an airport or a major truck route, you may be able to get rid of this by using a soft brush and isopropyl alcohol. If you’re unsure of the best way to clean your panels, avoid using strong cleaning fluids because they can damage the glass and cause streaking. Before you begin, make sure to turn off your solar panel, to ensure safety. After removing any dirt and oil, you can use a soft brush to remove surface debris.

Although cleaning solar panels isn’t necessary as often as most people think, it’s important to take care of them. Besides keeping the panels free of dust and dirt, they should be free of bird droppings as well. If you don’t feel like cleaning your panels, you can hire a professional to do it for you. Some companies even offer monthly cleanings. For those who are hesitant to clean their own solar panels, there are many companies that offer monthly cleanings for a nominal fee.

After a rainstorm

If your solar panels have been exposed to rain, you may need to clean them after the storm has passed. The average amount of dust and debris will wash off, but in highly polluted areas, there may be extra dirt and obscuring objects. In any case, you should clean your panels with a garden hose. Remember to never step on the panels or run the hose over them unless you are qualified to do so. You should also be careful not to get soap on the wiring underneath, so you should avoid power washing the panels. Clean the panels by hand – never power wash them – and make sure you wear a hat and safety harness.

Another way to clean your solar panels is by removing fallen leaves and pollen. Detrimental debris can be blown away by the wind, but wet leaves can stick to the panels. Heavy rain can act like glue. Therefore, removing leaves and pollen after a rainstorm will increase the effectiveness of your panels. Clean them as soon as possible after a rainstorm. A thorough cleaning will make them more efficient and last longer.

With a soft cloth

Using a gentle wiping motion, clean solar panels using a mixture of soap and water. Be sure to repeat this process several times to remove any thick dirt. Do not use hot water because the soapy water will evaporate before you have time to wipe away the dirty solution. Instead, use warm water and dish soap, and a soft cloth. Avoid touching the panels’ wiring underneath. Then, rinse the panels thoroughly to remove all dirt and debris.

When cleaning solar panels, safety is an important factor. When cleaning on a roof, you run the risk of slipping and damaging the panels. Especially if the roof is slippery and leaves are accumulating, slipping may not be the best idea. So be sure to take all necessary precautions and remember to always keep safety in mind! Clean your solar panels at least twice a year. Even a half-percent reduction in output will not add to your electric bill.

With a vehicle-mounted or electric rolling brush

Cleaning solar panels may be a time-consuming task that is often difficult to do properly. They can become soiled easily due to dirt and debris that may have accumulated over time. To ensure that your solar panels are kept clean and free of dust, debris, and dirt, you should use a gentle brush and warm water. Make sure to choose a soft, high-quality brush to avoid damaging the panels.

A high-quality vehicle-mounted or electric rolling brush will ensure the cleanest solar panels possible. A series of lighter cleaning cycles will reduce stress on the panels and the system. A brush can also be swung to one side, increasing the efficiency of the cleaning process. A vehicle-mounted brush is also more maneuverable than an electric one, making it easier to access difficult areas and make your work easier.

With a garden hose

If you don’t have the time to spend hours cleaning your solar panels, there is a simple solution: simply use a garden hose. A garden hose can be used for most cleaning purposes, and it can get rid of any buildup on the panels as long as you use the right cleaning agent. A soft cloth and dish soap will work well to clean the panels without damaging them. The sun’s UV rays will also dry the panels naturally.

If you’re not confident with the tools you’ll need, consider purchasing a solar panel cleaning solution from a home maintenance store. It is possible to get a solar panel cleaning solution in the store, but make sure that the solution isn’t too abrasive. Some of these solutions may leave a film on the panels, reducing their solar efficiency. A soft brush can remove dirt and dust without damaging them, so you’ll have a much safer, more effective way of cleaning them.

The average home can have a decrease in energy production of up to 10 to 20% in the summer months if the panels have never been cleaned. This means that it is costing you more money out of pocket because your panels are not efficiently producing energy.
It is recommended to clean your panels 2 times per year and especially at the beginning of summer. We have longer days in the summer which means more sun. That equals to more energy production.

We use a purified water system to clean all residential solar panels. This system allows us to safely clean the panels without leaving any water spots for a “spot free clean” every time. No Chemicals are ever used on the panels.
