Solar Panel

Rooftop Solar Panels get dirty primarily from wind-blown dust and pollen. As panels get dirtier, their output declines. A small amount of soiling may cause a 5% output decrease. However, when panels get very dirty, output can decrease up to 25%.


Why Do Solar Panels Need to Be Cleaned?

It's important to invest in regular cleaning for your solar panels so they maintain their efficiency and last as long as possible. Debris, dirt, and residue can accumulate on the surface of your solar panels, obstructing sunlight and reducing their ability to generate electricity.

Solar panels are sensitive products that require frequent maintenance. Debris buildup can create hotspots, permanently damaging the solar cells and reducing their performance and efficiency. Keeping your panels clean also helps prevent physical damage, extending their lifespan and reducing the need for costly replacements.

What Material Is Used to Clean Solar Panels?

Solar panels are highly sensitive and complex pieces of equipment that need to be cleaned with mild solutions and non-abrasive materials. Using the wrong material can unnecessarily damage your panels, resulting in costly repairs and reducing the electricity generated on your property.

The most commonly used cleaning materials include the following:

  • Distilled, deionized water: This type of water is free from minerals, meaning there won't be residue or water spots left over on your panels. Using regular water can cause hard water stains.
  • Mild soap/detergent: Mixing gentle soap with deionized water can help remove dirt and grime that's deeply embedded or baked onto the surface of your panels.
  • Soft-bristled brushes: If you need to scrub your panels to remove dirt and debris, using a soft, non-abrasive brush is ideal. It won't scratch the surface but still effectively cleans it.
  • Squeegees: After washing and cleaning your panels, squeegees are typically used to remove standing water and prevent water spots from forming on the surface.

How Frequently Should You Clean Your Solar Panels?

The frequency of your solar panel cleanings is impacted by the location of your equipment, local weather conditions, the surrounding environment, and the tilt or angle at which your panels are installed. Generally speaking, residential solar panels need to be cleaned at least once a year, and commercial solar panels should be cleaned bi-annually or quarterly, depending on your location.

Panels installed at a minimal tilt and in areas with lots of pollution or nearby greenery tend to accumulate dirt quickly. However, with regular rainfall, your solar panels may only need brief, annual cleaning to maintain optimal conditions.
