How To Clean Dust Off Solar Panels

Cleaning off the dust in your solar panels is easy. But there are a few important things that you need to consider to keep it working for years to come. In this post, we will show you how to clean dust off solar panels safely and easily.

6 Tips for Cleaning Solar Panels That Are Dusty

Solar panels are relatively simple to clean. Here are some ways to clean the dust off your solar panels:

1. Maintain Trees Well-Trimmed

Your solar panels will have leaves and branches that fall onto them. You should keep trees trimmed away from your panels. First, calculate the shadow cast on the tree when trimming it. You may discover that some areas below the tree are still receiving sunlight.

2. Regularly Sweep

You should sweep your solar panels every few weeks, especially if you have a lot of pollen and dust in the air. You can use a soft-bristled broom or a damp cloth to sweep your solar panels. This will help to remove dust buildup and maintain the panel’s functionality.

3. Use a Water Hose

You can blast the dust off with a water hose if it is very severe. Use a gentle spray to avoid getting water into the panel casing. Before you turn them on again, make sure they are completely dry.

4. A Professional Cleaner Is Available

A professional solar cleaner is recommended if you are not confident cleaning your solar panels, or if there is too much dust. Also, a professional cleaner will have the equipment and experience to quickly clean your panels.

5. In the Winter, Clean Your Panels

Winter is a great time to clean solar panels, as there’s less dust and pollen in winter. They will dry quicker in colder weather.

6. Monitor Your Panels

You should keep an eye on solar panels and make sure to clean them often, especially if they have become clogged with dust. This will ensure the highest efficiency and performance.

Can You Use Vinegar to Clean Solar Panels?

You can clean solar panels with vinegar. Vinegar is safe and can be used to clean solar panels. After using vinegar, wipe the panels with a soft cloth.

Are Solar Panels Waterproof?

Solar panels are not waterproof. Solar panels should not be washed with water as they could become damaged. To clean them, spray a little water from a hose.

How Can Professionals Clean Solar Panels

Cleaning companies employ different methods and processes. The general process is the following:

  • To assess the amount of dirt and debris built up on the panels, they are examined.
  • Spray the cleaning solution onto the panels, and let it soak in.
  • To remove dirt and grime, scrub the panels with a soft brush.
  • Rinse the panels with water to remove any remaining dirt.
  • To ensure that they are clean and free from damage, the panels should be dried and inspected.

How Often Should You Clean Your Solar Panels?

You should clean your solar panels at a minimum once per year. But they may require more frequent cleaning if they have become clogged with dirt and debris.
