Things You Will Need

If you want your solar panels to be as bright and beautiful as possible, you can do a couple of things. It doesn’t require much, but you do need the right equipment.

For one thing, you can always try following the manufacturer’s instructions. It will give you some suggestions about the best products you can use to clean them. Let’s take a closer look at each one in detail below.

  • Soft brush: If your solar panels have never been cleaned before, you will find a build-up of dirt that accumulates over time. It might prove hard to remove with regular washing so a softer brush would be better than a lint-free cloth. Since most solar garden lights are small, it makes sense to use a brush, especially when cleaning them.
  • Alcohol: It can help remove oily stains and make solar panels shine.
  •  Microfiber cloth or sponge: This is to remove surface dirt and easily removable grime. It is best to use a towel or an old t-shirt or even a kitchen sponge to rinse things off.
  • Cleaning solution: A gentle detergent would work great. Never mix in bleach or other chemicals.
  • Dry towel: These durable cotton towels are not just great to scrub with, but they are also effective for drying and polishing your solar panels.
  •  Last but not least, you should get yourself rubber gloves if you have sensitive hands.

Step 1: Get A Cleaning Solution

To get started, you need to prepare your cleaning solution. If you don’t have a specialized one, make a mixture of 50% water and 50% of soap.

Remember never to put bleach or strong chemicals into the solution. If your solar panels are coated with photovoltaic cells, bleach will make them stop working properly. Moreover, the lights on your lawn decorations will not shine as bright as they should.

Step 2: Clean The Top Glass Surface

The next step is to remove the cover of your garden lights. Then, you need to clean the top surface of the solar panels with a washcloth or sponge by rubbing back and forth. When cleaning a stubborn stain or scratches, use your soft brush to loosen things up.

Avoid using metal objects to clean your glass. Using a metal scouring pad or harsh abrasive products will damage the surface and cause small scratches that lead to poor performance.

To ensure that your solar cell is as clean and cleanable as possible, use alcohol to clean the solar panels. If your panels have some oily stains on the surface, try spot cleaning with alcohol.

Once you are done with your work, wash the soap off by rinsing it off in the water. Then remove any excess moisture by patting it dry with a towel. Do not get any water on the lid on top of the solar panel because this is where your batteries are inserted.

Step 3: Clean The Bottom

Once the covers of your lights are dry, you can clean the rest of your fixtures. You will want to run water over your fixtures before cleaning them for the dirt to come off more easily. Repeat the process using a soft quality cloth and gently scrub the fixtures. Once finished cleaning, get a towel and dry everything off.

There you have it! The finished product is now a bright, shiny, and fully functional solar panel. Your garden lights look like new again!

Therefore, cleaning them once in a while can bring many benefits to your home.

First, you won’t have to spend money on diminished energy output. If you let dirt and dust build-up on your solar panels, they will increasingly become susceptible to damage as time wears on. You can lose all of that cost from warranty payments and diminished energy returns.
