Is it OK to clean solar panels with Windex?

It is not recommended to use Windex or any other type of glass cleaner on solar panels. Windex and other glass cleaners contain chemicals that can damage the surface of the solar panel, reducing its effectiveness and potentially shortening its lifespan.

Solar panels are made of a special type of glass that is designed to withstand the elements, but they can still be damaged by certain chemicals.

The chemicals in glass cleaners can strip the protective coating on the solar panel, leaving it vulnerable to scratches, water spots, and other damage.

The best way to clean solar panels is to use a mild detergent and water, and a soft brush or cloth to gently scrub away any dirt or debris.

It’s important to avoid using high-pressure water or abrasive materials, as they can scratch the surface of the solar panel.

Additionally, if the solar panels are installed at a high place or difficult to reach, it’s best to contact a professional cleaner that can safely and effectively clean the solar panels. You will want to look at having your solar panels cleaned at-least every 6 to 12 months to ensure that they stay at their most efficient and continue to work properly.

What do professionals use to clean solar panels?

Professionals generally use specialized cleaning solutions and equipment to clean solar panels. These cleaning solutions are specifically designed to be safe for use on solar panels and to effectively remove dirt, grime, and other debris without damaging the surface.

Common cleaning solutions used by professionals include:

• Mild detergents: Mild detergents such as dish soap or a solution of water and vinegar can be used to clean solar panels. These solutions are safe for use on solar panels and can effectively remove dirt and debris.
• Purified water: Purified water is also used to clean solar panels by some professional cleaners. The purified water is used to flush off the dirt and debris from the surface of the solar panel. This method is known as “pure water cleaning”
• Specialized cleaning solutions: Some professional cleaners use specialized cleaning solutions that are designed specifically for use on solar panels. These solutions can be more effective in removing certain types of stains or grime than mild detergents or water alone.

In addition to cleaning solutions, professionals also use specialized equipment to clean solar panels. This may include:

• Soft-bristled brushes: Soft-bristled brushes are used to gently scrub away dirt and debris from the surface of the solar panel.
• Extension poles: Extension poles are used to reach high or hard-to-reach areas of the solar panel.
• Purified water delivery systems: Some professional cleaners use purified water delivery systems to flush off dirt and debris from the solar panel surface.

It’s important to understand that solar panels are delicate and should be handled with care.

Therefore, it’s always best to contact professional cleaners who have the experience and specialized equipment to safely and effectively clean solar panels.
