What Are Solar Lights?

Solar lights are solar lamps or lanterns that draw power from the sun. Unlike regular lights, which require electricity, these are solar-powered. Essentially, they use batteries that get charged with the sun’s power. It stores solar energy and converts it to electricity to illuminate your backyard or patio.

Daylight is crucial for solar lights as they use it to charge completely and give you light at night.

Often, the charging capability gets affected due to rain, snow, and lack of sunlight. Due to dirt, dust, grime, and bird droppings, unclean solar panels also contribute to a lack of sun exposure. That’s why you must clean your solar lights.

What To Use To Clean The Solar Lights?

Cleaning solar lights is a must to improve their efficacy. However, there is a methodology and select tools to clean them successfully. Below are the tools you can use to clean your solar panels:

Damp Cloth

You can use a damp cloth to wipe the solar lights and panels. However, it would be best to have a handy dry cloth to wipe the solar lights dry after wiping them with soapy water and a damp cloth. The dry cloth is necessary to prevent any damage to the solar-powered lights due to water.

Dish Soap

Dish soap or soapy water will help loosen the dirt on the surface of the solar lights and panels. You can then easily wipe it clean. Ideally, using a regular dishwashing liquid would be best as it has fewer chemicals and will not damage the solar lights’ electric components.

Soft Brush Or Fine Grit Sandpaper

At times, your solar light might have accumulated dirt and debris that might be difficult to remove with a damp cloth or sponge. Also, the light might have stubborn dust. You might use a soft brush and fine-grit sandpaper to scrub off the difficult-to-remove dirt. The bonus is that the soft brush will help you reach the narrow crevices of the solar cell.

Nail Polish Remover

When the surface of the solar panel and light becomes white, exposure to sunlight reduces. You can use a ball of cotton wool with a bit of nail polish remover to clean the white cast. Your solar lights will shine brightly and get exposure to the sun properly.

How To Clean The Solar Lights?

Once you know the tools required to clean your solar panels, you need to follow a step-by-step process to clean the solar lights. Also, cleaning your solar lights in the evening or early morning when the sun goes down would be best. Otherwise, you will find the lights too hot to handle.

Following are the steps for cleaning the solar lights:

Step 1: Prepare the Soapy water

Firstly, make your soapy water ready to loosen the dirt and grime. Mix ½ teaspoon of dish soap, ¼ cup of vinegar, and 2 cups of water. This is a gentle yet effective solution to clean your panels.

Step 2: Clean the Top Cover

Next, you should remove the top cover from the solar light. You can use a damp cloth, sponge, and soapy water to wipe the top cover. Then, wash it with plain water to eliminate soap residue without letting water on the lid. After that, wipe it dry with a dry cloth and leave it in the sun.

Step 3: Cleaning the Solar Light Fixture

You can start cleaning the solar light fixture with a sponge or damp cloth. Ensure you use light pressure when cleaning the fixture to avoid damaging the solar panel. Once you clean it, ensure you wash it with water and wipe it dry.

Step 4: Cleaning the Solar Cell

For cleaning the solar cell, first, tape the solar cell to protect the plastic and metal parts from getting scuffed. Then, use fine grit sandpaper, a soft brush, and soapy water with low pressure to wipe the grease and dirt on the solar cell. Use a little alcohol or nail polish remover to remove leftover oil and dirt on the cell.

Step 5: Cleaning the Cloudy Panels

Next, clean the cloudy panels with a cotton ball and nail polish remover. Alternatively, you can spray a clear coat on the solar panels with an overspray protector. This will remove the clouded portions and make your solar panels brighter.

Step 6: Cleaning the Battery Terminals

Finally, you must check the battery for any white dust. Suppose you find that your battery is facing corrosion. So, use sandpaper and a brush to remove the white dust from the terminals and the battery.

Also, check if the batteries need to be replaced. Generally, the battery lasts for 3-4 years. Nevertheless, it’s good to double-check to improve the solar light’s efficacy.
