So you’re cleaning your solar panels. It’s a good decision because it’s vital to regularly clean the solar panels to ensure that they work efficiently.

In this blog, we’ll provide you with a comprehensive guide on how to clean them effectively and discuss the benefits of cleaning solar panels.

Before we begin, let’s discuss why and when you should clean your solar panels.


Why Clean Solar Panels?

So, why should you even bother to clean the solar panels? It is because solar panels are constantly exposed to the elements, and over time, they can accumulate dirt, dust, pollen, bird droppings, and even mineral deposits from rainwater.

When these contaminants cover the surface of your solar panels, they can reduce the panel’s ability to absorb sunlight effectively. As a result of this, the energy production of your solar system can decrease, and you may not be getting the most out of your investment.

When Should You Clean Your Solar Panels?

You should clean your solar panels when you notice a visible buildup of dirt, dust, bird droppings, or other contaminants that could obstruct sunlight. The process of cleaning solar panels remains the same regardless of dust, dirt, bird droppings, or weather conditions. However, the frequency of cleaning may vary depending on your location, climate, and environmental factors.

It’s advisable to perform a visual inspection periodically, especially after adverse weather conditions or during seasons with increased pollen or debris. It is good practice that you should follow the manufacturer’s recommendations for maintenance and cleaning to ensure optimal energy production from your solar panels.


Cleaning Solar Panels: Step-by-Step Guide

Here are some steps that you need to follow in order to clean your solar panels:

1). Safety First:

  • You should put safety first before you begin. You should ensure that the weather conditions are favorable, and that the solar panels are not too hot. For this, it is better to clean them in the early morning.
  • You should wear appropriate safety gear, including gloves, non-slip shoes.
  • Keep in mind that climbing on the roof may be dangerous, and it’s generally best to hire a professional to help if your roof is too sloppy. If your roof is rather flat, then you can easily climb on it. Make sure to use an extension ladder for safety.


 2). Gather Your Tools:

  • You’ll need a few essential tools for the job: a soft-bristle brush with an extended handle, a squeegee with a long handle, a bucket, a hose with a gentle spray nozzle, and a mild detergent or soap. You can totally skip using a mild soap if there are no bird droppings.


3). Brush Away Debris:

  • You can begin cleaning the solar panels by removing loose dirt, dust, and leaves with a dry soft-bristle brush.
  • It is recommended that you do not use abrasive brushes or harsh chemicals on your panels because they can scratch or damage them.


 4). Mix a Cleaning Solution:

  • Fill your bucket with a mixture of water and a small amount of mild detergent or soap. The water should not be too cold or too hot. In this solution, the panels are not damaged, and the dirt is effectively removed.


5). Scrub and Rinse:

  • Dip the brush into the soapy water and scrub the solar panels gently, paying attention to any stubborn spots or bird droppings.
  • After scrubbing, use the hose with a gentle spray nozzle to rinse off the soapy residue thoroughly.


6). Squeegee for a Streak-Free Finish:

  • To prevent water spots and streaks on the panels, use the squeegee to remove excess water. You should work your way down from the top in a smooth, horizontal motion.


7). Check for Shaded Areas:

  • You should pay attention to shaded areas and corners where dirt can accumulate during the cleaning process.


8). Repeat as Needed:

  • It may be necessary to clean your solar panels regularly, such as every few months or as recommended by the manufacturer, depending on where you live and the conditions in which they are located.
