Vinegar isn’t a great disinfectant but works wonders for cleaning solar panel glass. It will break down dust and debris buildup leaving your solar panels good as new!

Many people keep vinegar in their cleaning supply closet for everyday tasks around the house. It’s considered safe for most surfaces. Before using vinegar to clean your solar panel glass, you should ask if it’s truly safe. Damaged solar panels can cost a lot to replace!

In this article, I share how safe it is to use vinegar on solar panel glass, explain the best method, and list the pros and cons of vinegar as a cleaning agent. 

Is It Safe To Clean Solar Panels With Vinegar?

It is safe to use vinegar to clean your solar panels. Your panels should be just fine and cleaner than ever before!

Vinegar is actually considered safer than other options like detergents, regular soaps, and hard chemicals. 

Just be sure to use cleaning vinegar instead of the regular cooking vinegar you can buy in grocery stores. Cooking vinegar has much more acid, harming your solar panels. 

If you’re still unsure, diluting the vinegar in some water could make it a little weaker. This will ensure that nothing gets damaged, and the water adds a little extra cleaning power.

How To Use Vinegar to Clean Solar Panels

Step 1: Get Your Supplies Ready

You’ll need:

  • White cleaning vinegar
  • Mineral-free/ deionized water
  • A hose or bucket
  • A soft cloth or window cleaner

Ensure you have the right vinegar before you start. Dilute your vinegar with some deionized water (mineral-free) to prevent any marks or damage on your panels. 

Step 2: Fix Any Cracks on Your Solar Panels

Hosing your solar panels off with water or vinegar could be catastrophic if there are small cracks in the glass. The water could slip through and damage your solar panel cells or wiring.

Check the manual for ways to repair these cracks or send the solar panel in to have it checked out and fixed.

Step 3: Wipe Your Solar Panels Down Manually

Use your hands to carefully wipe off leaves, branches, and other large pieces of dirt. Then, use a cloth or window cleaning device to physically wipe down the glass surface. 

This should remove all the dust and dirt that has accumulated over time. It may turn into mud if you simply add water before wiping it down.

Step 4: Wash Your Solar Panels With Water

Using a hose may be quicker to complete this step, but you can use a bucket of water too. Simply spray the surface with water to ensure that you have removed all of the dirt.

You could scratch your solar panels if you start rubbing or wiping the glass with vinegar water before removing all the dirt.

Step 5: Make A Diluted Vinegar Mixture

Use mineral-free water to dilute your vinegar. If you’re working with many solar panels and large amounts of cleaning fluids, use the following ratio: 

1 cup vinegar: 8 cups mineral-free water. 

Do not add anything else to the mixture. 

Step 6: Use The Vinegar Mixture To Cover The Surface of Your Solar Panels

Don’t pour a whole bottle of pure vinegar over your solar panels. Use a misting bottle or soft cloth to add diluted vinegar to the glass surface.

You should cover the entire solar panel surface with vinegar water.

Step 7: Wipe The Solar Panel Glass Again

Use a new, clean cloth to give the glass surface of your solar panels another wipe. 

Vinegar breaks down dirt layers even further. There should be some dirt on the cloth you overlooked on the solar panel. 

Step 8: Use Water To Clean Your Solar Panels Again

This is a repeat of step 4. You should only be hosing off the surface or using a bucket to pour clean water over it. 

Step 9: Leave Your Solar Panels to Dry Before Setting It Back Up

You won’t be able to use your solar panels for another hour after completing step 8. They need to properly dry to prevent damage due to wetness.

Vinegar vs. Other Cleaning Products

Vinegar is considered the best cleaning product to use on your solar panels. It contains acid that literally eats through all of the dirt on them.

It’s better than regular soap and water since vinegar doesn’t leave an invisible layer of dirt or soap on your panels. It’s also cheaper than this option. 

Soap and water can also leave streaks on your panel glass, and the wrong detergent will probably leave stains. However, soap is still a better option than hard chemicals.
