How Much Is Solar Panel Cleaning

Wednesday, October 05, 2022

How much does it cost to have your solar panels cleaned? This is a question that we get asked a lot, and it can be difficult to answer. The reason for this is that there are a lot of variables that come into play when determining the cost of solar panel cleaning.

In this article, we'll break down some of the main factors that will affect the cost of having your solar panels cleaned.
Solar panel cleaning is important because it helps keep your panels operating at peak efficiency.

When dirt and debris build up on your panels, they can block sunlight from reaching the photovoltaic cells. This can reduce the amount of power that your panels can generate. Sometimes, it can even cause your panels to stop working altogether.

Types of Solar Panel Cleaning

Different types of solar panel cleaning exist, each with its own benefits and drawbacks. The most common type of solar panel cleaning is manual cleaning. This involves using a soft cloth or brush to remove dust and debris from the panels. Manual cleaning is typically the most affordable option, but it can be time-consuming and challenging to reach all areas of the panels.

Another type of solar panel cleaning is automated cleaning. This uses machines to clean the panels, which can be more effective than manual cleaning but is typically more expensive. Automated systems can also be less reliable and may require more maintenance than manual systems.

The final type of solar panel cleaning is chemical cleaning. This involves using chemicals to clean the panels, which can be effective, but can also be dangerous. Chemical cleaning should only be performed by trained professionals.

What Causes Solar Panels to Be Dirty

Solar panels are designed to capture sunlight and convert it into electricity. But over time, they can get dirty, which reduces their efficiency. There are a few different causes of this.

One cause is dust and debris. As the panels are exposed to the elements, they can accumulate dust and other particles on their surface. This reduces the amount of sunlight that they can capture, and thus reduces their output.

Another cause is bird droppings. If birds perch on the panels or fly overhead and deposit droppings, this can also reduce their efficiency. The droppings can block sunlight from reaching the panel's surface or can reflect it away. Finally, tree leaves can also cause solar panels to be dirty. If leaves fall on the panels and block sunlight, they can reduce the amount of electricity that the panels generate.

When Should You Consider Solar Panel Cleaning?

You might not think that solar panel cleaning is something you need to worry about, but it can be pretty significant.

Dust, dirt, and other debris can build up on your panels over time, reducing their efficiency. In some cases, it might even be necessary to have your panels professionally cleaned in order to keep them working properly.

So, when should you start thinking about solar panel cleaning? Here are a few things to keep in mind:

  • If your panels are located in a dusty or dirty area, they may need to be cleaned more often. This is especially true if there's been a lot of construction or other activity nearby that has generated dust.
  • If your panels are located in an area with a lot of trees or other vegetation, they may also need to be cleaned more often. Leaves and other debris can fall on your panels and cause them to be less efficient.
  • If you notice that your energy bills have been gradually increasing, it might be time to have your panels cleaned. Dust and dirt can reduce the amount of sunlight that's able to reach the solar cells, which means they won't be able to generate as much power.
  • ​Finally, if you just want to keep your panels looking their best, regular cleaning can help.

Most solar panels only need to be cleaned once or twice a year, although this can vary depending on the location and type of panel. Dust, pollen, and other debris can build up on the panels over time, reducing their efficiency.

In general, it's best to clean solar panels when they're first installed, and then every few months after that. If you live in an area with a lot of air pollution or dust, you may need to clean them more often.

Solar Panel Cleaning - What Factors Should You Consider?

When it comes to solar panel cleaning, there are a few key factors that you need to consider in order to ensure that your panels are kept clean and functioning properly. Here are nine of the most important factors you need to consider:

Use the Right Tools

When cleaning your solar panels, it’s important to use the right tools. A soft bristle brush or cloth is usually all you need to remove any dirt or debris that has accumulated on the surface of the panel. However, if there is any stubborn grime build-up, you may need to use a mild soap solution and a sponge. Avoid using harsh chemicals or abrasive materials, as these can damage the panel's surface.

Be Careful of Scratches

The surface of solar panels is coated with a thin layer of glass. This glass is very fragile and can easily be scratched. When cleaning your panels, be careful not to use any abrasive materials or scrub too aggressively, as this can damage the panel's surface.

Avoid Cleaning in Direct Sunlight

Solar panels should never be cleaned in direct sunlight. The heat from the sun can cause the soap solution to evaporate before you have a chance to rinse it off, which can leave streaks or spots on the panel's surface. It’s best to clean your panels in the morning or evening when the sun is not shining directly on them.

Don’t Use a Pressure Washer

Pressure washers are too powerful for solar panels and can damage the delicate surface of the panel. If you need to remove stubborn dirt or grime, use a soft bristle brush or cloth instead.

Rinse Thoroughly After Cleaning

It’s essential to rinse the panels thoroughly after cleaning them with the soap solution. If there is any soap residue left on the surface of the panel, it can attract dirt and debris, which will reduce the efficiency of the panel.

Be Careful of Heights

Solar panels are typically installed on rooftops, which can be dangerous. If you don’t feel comfortable climbing up to clean your panels, hire a professional to do it for you.

Avoid Using Abrasive Materials

Abrasive materials can scratch the surface of solar panels and reduce their efficiency. When cleaning your panels, only use soft cloths, brushes, or sponges.

You should only use mild soap and water to clean solar panels. Avoid using harsh cleaners or solvents, as these can damage the panel's surface. If you need to remove stubborn dirt or grime, use a soft bristle brush or cloth instead of a pressure washer.

Follow Manufacturer’s Instructions

When in doubt, always follow the manufacturer’s instructions for cleaning and maintenance. Each type of solar panel is different and may require special care.

Have a Professional Do It If Needed

When in doubt, always follow the manufacturer’s instructions for cleaning and maintenance. Each type of solar panel is different and may require special care.

Don’t Use Chemicals Near Your Panels

Chemicals can damage the surface of solar panels, so it’s important to avoid using them near your panels. If you need to remove stubborn dirt or grime, use a soft bristle brush or cloth instead of a pressure washer.

How to Maximize Your Solar Panels' Lifespan

Solar panels are a significant investment, so it’s important to take care of them to ensure they last for many years. Here are a few tips for maximizing the lifespan of your solar panels:

  • Keep them clean: As we’ve discussed, it’s important to keep your solar panels clean to ensure they’re working at peak efficiency.
  • Inspect them regularly: In addition to keeping them clean, you should also inspect your solar panels on a regular basis. Look for signs of damage, such as cracks or dents, and make sure the connections are secure.
  • Repair any damage immediately: If you do find any damage, it’s important to repair it as soon as possible to prevent further damage.
  • Store them properly: If you’re not using your solar panels, be sure to store them in a cool, dry place. This will help to prevent any damage from the elements.

By following these tips, you can help ensure your solar panels have a long lifespan. Solar panels are a great investment, and by taking care of them, you can enjoy their benefits for many years to come.
