How to Safely Clean Solar Modules? 3 Easy Steps to Follow


Solar panels are generally considered self-cleaning, but in some areas or when the tilt of the modules are minimal, dust or other substances can build up over time and impact the electricity generated. Generally, the saying “if it ain’t broke, don’t fix it” applies here perfectly. If you don’t visually see grime build-up or a lower efficiency in production, there is no need to clean it. If you notice that your production is down, it might be because dirty solar panels work less efficiently because of the shading created by the dirt. Before your resort to cleaning it yourself, consider hiring professionals who have experience washing solar panels on LA roofs.

Here are three main steps you need to take to clean your solar modules safely:

  1. Use safety methods
  2. Have the correct materials
  3. Consider the optimal time to clean solar modules

Top Cleaning Methods For Solar Modules




The first step you need to take is following the manual for your solar panels and turning them off. If you’d like to wash solar modules without help, the general rule of thumb is, don’t clean your panels from the roof. It is dangerous for both the person cleaning it and for the panels themselves. You can use a high-quality soft brush or a cloth-covered sponge with a suitable nozzle for your hose to clean solar modules. If cleaning your modules from the ground is impossible, don’t attempt to clean them without safety equipment or training. You can pick a reliable solar panel cleaning service in LA to hire for the job.


The Most Suitable Materials To Use




Even though solar panels are highly durable because of the glass coating, any pressure can harm the solar cells. You can invest in good solar modules cleaning solutions.

If you don’t want to spend too much money on it, clean dirty solar modules with vinegar.
All you have to do is mix:


  1. 1/2 a teaspoon of non-abrasive soap or detergent
  2. 2 cups of water
  3. 1/4th of a cup of vinegar

Congratulations, you’ve created a homemade cleaning solution! It works better than any other material. Don’t use any abrasive products or metal equipment. Any damage to the glass casing of the panels can create shading and lower energy production. 



Does Timing Matter When Cleaning?




The sun can dry out the water and smear the dirt on your modules, creating more shadows. That’s why the best time for solar panel cleaning is overcast, early in the morning or evening.

Early morning is a great time for cleaning since there is the added benefit of dew that sits on the panels overnight. You can use less energy and less water on cleaning the panels. 


In general, cleaning your solar panels once in a while is a good idea, but it is always recommended to turn to certified cleaners for safety purposes. You can send a request to trusted and qualified professionals to do the job for you.
