Solar panels are an expensive investment because of their costs, and in order to guarantee long-term benefits, solar panels cleaning and maintenance are required. In this article, we’ll review some solar panel maintenance and cleaning techniques.

Purchasing high-quality solar panels can save your long-term costs by lowering the need for upkeep and cleaning. By selecting a trustworthy solar panel installation and routinely checking your panels, you can make sure they run as efficiently as possible.

Getting the best quotations from several certified installers will help you get the greatest value for your needs and budget when purchasing high-quality solar panels. To begin, click the button below.

Importance of Solar Panels Cleaning

Compared to conventional power generation systems, solar power systems require less maintenance because they don’t have any moving parts when producing electricity. As an illustration:

Unlike wind turbines, which feature rotating gearboxes and blades, photovoltaic modules are not subjected to high temperatures during the combustion of fossil fuels. However, dust and other particles can gather more readily on the surface of solar panels because they are immobile.

A build-up of dust can reduce your solar panels’ energy output by half if it prevents 50% of the sunlight from reaching them. This decline in productivity may adversely affect electric bill savings; if you were previously saving $100 a month, you may notice a dip to about $50.

Maintaining your solar panels’ optimal performance ensures that your system produces the anticipated amount of electricity. An unclean solar energy system runs less efficiently, which can lead to higher electricity costs and a more extended payback period. Professional solar panel cleaners refer to the efficiency loss brought on by dust and dirt accumulation on your PV system as “soiling losses.”

Understanding Solar Panel Components

Photovoltaic cells used in solar panels are completely enclosed by other materials, shielding them from environmental factors, including dust, filth, bird droppings, and weather. But with time, dirt can gather on external surfaces, so you should choose solar panel frequently just like roof cleaning.

Clean Glass Cover

A solar panel’s PV cells are shielded from the elements by a clear glass cover. A soft bristle brush or squeegee are good examples of non-abrasive cleaning instruments that work well for cleaning glass surfaces. Steer clear of wire brushes, roof rakes, and other potentially scratchy instruments.

Solar panels can be cleaned using a garden hose, but you should never do this while they are hot because the sudden shift in temperature can shatter the glass. Remember that solar modules can remain heated long after the sun sets, particularly during the summer.

When cleaning your panels, make sure you have access to clean water. The goal of cleaning your panels with hard water is defeated because the water evaporates and leaves behind a mineral layer.

Clean Aluminium Frame

The aluminium frame of solar panels serves as the structural anchor for all other parts. In order to increase corrosion resistance and make the aluminum frame appropriate for outside usage, solar producers apply powder coating and other treatments. On the other hand, the glass cover and the frame are both continuously exposed to dust.

You may safely wash the aluminium frame with a regular water hose because it resists corrosion. Never use a pressure washer as this could void the product’s guarantee and harm the seals surrounding the metal frame. Avoid using cleaning solutions that contain detergents or other chemicals as they may cause harm to the seals.

Washing your panels might not be sufficient to get rid of dirt if they haven’t been cleaned in a while. In this instance, brushing the dried-up dirt away is preferable to utilising a hose. You should avoid chemical cleaners, but you can clean areas with a lot of filth build-up by using a little soapy water.

Clean Polymer and Junction Box

A backsheet, usually composed of a sturdy polymer, covers the rear of a solar panel. A junction box with electrical connectors for wiring several panels into a string circuit is also located on the back surface.

Compared to the glass cover and aluminum frame of a panel, the backsheet and junction box require less cleaning because they are not always looking outward.

The junction box and backsheet of a rooftop solar installation are concealed by a tiny space that exists between the surface of the roof cleaning and the back of the panels. There is less exposure to dust and dirt at this position. However, a solar carport or ground-mount system exposes your panels to airborne dust from all directions. Here, regular cleaning of the rear surface could also be necessary.

The back sheets can be cleaned using the same methods as the aluminium frame and glass cover. Pressure washers and chemical agents should be avoided; soft brushes and non-pressurised water are appropriate.

Avoid opening junction boxes or tampering with electrical connections. If there is a workmanship warranty on your solar installation, you can get in touch with your provider to have any electrical issues looked at. Additionally, a lot of businesses provide expert solar panel cleaning services.

How Often Should You Clean Solar Panels?

Although cleaning requirements could vary based on site conditions, many solar manufacturers and installers advise solar panel cleaning at least twice a year. If your house is adjacent to an industrial area or construction site, your panels might require more cleaning. Expect a lot of dust in the air, which can quickly build up on your photovoltaic system. Locations with a lot of trees or other vegetation should be avoided because pollen and leaves might accumulate on your panels.

Your panels will only need a little cleaning over their lifespan if you live in an area with regular rainfall because the rain washes away most of the dirt.

Conclusion

Maintaining your solar panels can guarantee their longevity and maximum efficiency. Steer clear of strong chemicals and high-pressure water, and use soft brushes and gentle cleaning solutions instead. Thermal shock damage can be avoided by cleaning in the early morning or late at night. Maintaining your investment properly protects it and maximises energy output.
