Cleaning your Solar Panels in 3 Easy Steps.

Updated: Oct 30, 2019

When it is time to clean your solar panels, you can either choose to do it yourself or hire a professional to do the job. If you would like a professional to do the job, contact First Response Solar today to get your panels cleaned with our professional filtration system.


The best time to get your solar panels cleaned is in the morning before they get too hot and for an added bonus, the morning dew can soften the particles on top of the solar panel before you get started.


It is always a good idea to check with the manufacturer of the solar panel to check if they have a specific or recommended cleaning manual on how to clean their panels.


If you are a 'do-it-yourself' person, here is the process to cleaning your solar system:



1) Assemble Equipment

Assemble all the needed equipment to clean your solar panels. This will include

attaching the garden hose to the RV brush, setting the ladder in a safe place to

access to the roof and assembling any and all safety equipment.



Recommended Materials:

1. Garden Hose.

2. Ladder.

3. Safety equipment

4. Soft Bristle RV Brush with water flow through. (We personally would recommend one with an on/off valve for the water.)


2) Clean you Solar Panels


Thinking through a plan of action for cleaning your panels before getting on the roof can save time, water, and keep you out of the heat!


Panels should be cleaned from top to bottom so the dirt and particles can naturally run off of the panels. Once the panels are wet, it is difficult to see areas that you have missed, so it is important to move in a methodical manner.


Start cleaning in one top corners of the solar system and move the brush across the panel in a smooth motion with constant pressure. (We recommend not using soap or any other cleaning solutions as they can potentially damage panels. Water and a good scrub should do the trick!) Pollen and other particles may need further attention. Most importantly, make sure to stay safe! Slow and steady is always the way to go.


3) See the Results!

We typically see an increase in energy production between 5-10%. Results tend to be higher when the panels are cleaned professionally. It is recommended to clean your solar panels at least 1 - 2 times per year. If you have a system that is at a lower angle, the area you're in produces larger amounts of dust, or you have a large number of trees nearby, cleaning can increase anywhere from 3 - 4 times per year.



From the system we cleaned on August 11, 2018 (pictures above) we saw around 10% increase in production. The chart below shows some of the best results we have seen from a professionally cleaned system. An almost 50% production increase!


Until next time!
