"Since it's a concentrate very little is needed. And because of this it will last for a long time. This was my first attempt at cleaning my solar panels and I am so glad I got thus cleaner. Wet the panels down, brush cleaner on the panels, and then rinse panels with water and the panels dried crystal clear! I'll definitely be cleaning the panels more often ."

How to clean solar lights: Preparation for Cleaning

Cleaning Solar Panels

Safety Measures

  • Turn off the lights: Before cleaning your solar lights, make sure to turn them off to avoid any electrical hazards.
  • Wear protective gear: It is recommended to wear gloves and safety goggles to protect your hands and eyes from any debris or cleaning solutions.
  • Be careful with ladders: If your solar lights are installed in hard-to-reach places, use a stable ladder and have someone hold it for you.

A Simple and Effective Method: Cleaning Solar Lights with Vinegar

To get started, mix one part vinegar with three parts water in a spray bottle. (For larger panels use a bucket)

Next, spray the solution onto the solar lights and use a cloth or sponge to wipe away any dirt or grime. Be sure to clean the solar panel thoroughly, as this is the part of the light that absorbs sunlight and converts it into energy.

If the solar lights are particularly dirty, you can also add a few drops of liquid detergent to the vinegar solution to give it some extra cleaning power. However, be sure to rinse the lights thoroughly with water after cleaning to remove any soap residue.

Alternative Cleaning Methods

While vinegar is a great natural cleaning agent for solar lights, there are other methods that can be used to clean them effectively. Here are a few alternative methods to consider:

Using Toothpaste

Yes, toothpaste can be used to clean solar lights! Simply apply a small amount of toothpaste to a soft cloth and gently rub it onto the surface of the solar panel. Then, rinse the panel with water and dry it off with a clean cloth. The mild abrasives in toothpaste can help remove dirt and grime from the panel, leaving it looking clean and shiny.

Dish Soap and Water

If you don’t have vinegar or toothpaste on hand, dish soap and water can also be used to clean solar lights. Mix a small amount of dish soap with water in a bucket, then dip a soft cloth or sponge into the solution and use it to gently scrub the solar panel. Rinse the panel with clean water and dry it off with a clean cloth.

It’s important to note that when using any cleaning method, you should avoid using abrasive materials or harsh chemicals that could damage the solar panel.

Cleaning the Interior

To clean the interior of the light fixture, you will need a screwdriver, a soft-bristle brush or toothbrush, and a microfiber cloth or sponge. Here are the steps:

  1. Turn off the solar light and remove it from the ground or mounting bracket.
  2. Use a screwdriver to remove the screws that hold the fixture’s cover in place.
  3. Use a soft-bristle brush or toothbrush to remove any loose debris or dirt from the interior of the fixture.
  4. Use a microfiber cloth or sponge to wipe the interior of the fixture clean.
  5. Replace the cover and secure it with the screws.


What products can I use to clean my solar panels?

Most solar panel manufacturers recommend using plain tap water or de-ionized water with a scrubbing brush to remove dust, dirt, or other debris. You can also use ethanol, glass cleaner, or isopropyl alcohol for spot-cleaning solar panels, but avoid using soap or abrasive materials that can damage the panels.

What is the cheapest way to clean solar panels?

The cheapest way to clean solar panels is to use plain tap water and a soft-bristled brush or sponge to remove dirt and debris. You can also use a garden hose or a bucket of water to rinse the panels. Avoid using soap or other cleaning agents that can leave residue and damage the panels.

Can you leave solar lights out in the rain?

Yes, most solar lights can be left out in the rain as they are designed to be weatherproof and withstand various weather conditions. However, it is recommended to take them inside during extremely bad weather or when they are not going to be used for an extended period of time.
