How to Remove Paint from Solar Panels: Guide to Solar Panel Cleaning

How to remove paint from solar panels? Solar panels are a great investment for homeowners who are looking to save money on their electric bills. But, what if you have some paint stains on your solar panels?

These panels help you provide a steady supply of clean energy which is why you might be frustrated when you find paint stains on them. These stains are very difficult to clean and often require special equipment. 

In this blog, we’re going to take a look at how you can remove these paint stains without damaging the panels and without spending a lot of money.

Before moving forward, let me first discuss briefly why you should clean your solar modules on a regular basis, along with their benefits.

Is it necessary to clean solar panels regularly?

It’s important to note that solar panels are an investment, so you want to make sure that they are in the best, or at least a safe, condition. 

Solar modules can be damaged by dirt, tree sap, bird droppings, and other debris. However, you don’t have to clean them daily. In fact, it’s not necessary to even clean them monthly.

However, cleaning solar panels weekly can be a great way to avoid dirt and dust from accumulating on them. 

Any dirt, dust, or lose materials that are on solar panels can cause them to stop absorbing sunlight, which can reduce the efficiency of the solar panels.

So, it’s not necessary to clean solar panels every week – however, if you want to boost efficiency or just want to make sure that they look cleaner, then I recommended cleaning them once a week.

How to remove paint from Solar Panels?

Solar panels are important for the environment and their efficiency is often compromised by paint stains. These stains need to be removed as soon as possible.

In order to remove paint stains from solar panels, you have to first check the type of paint stain. 

  • If it is oil-based, then use a brush to scrub the area with a mild dishwashing liquid. 
  • If it is water-based, then use a mixture of vinegar and water or a commercial cleaning agent. 

Next, you have to follow the following process:

1) Brush off loose dirt and grime with a soft brush or vacuum cleaner attachment first. If the paint is dry and hard to remove, use a mild dishwashing liquid mixed with water instead of soap or detergent.

This will break down the paint without damaging the surface of the panel as much as soap would do.

2) Spray or pour some dishwashing liquid onto the stain and scrub gently with a soft cloth or sponge until it completely vanishes.

Make sure to not use harsh chemicals to remove paint stains from solar panels as it may degrade the solar cells.
