How to Clean Solar Panels

How to Clean Solar Panels

Solar panel cleaning can be as easy as counting to three. It may not take three seconds to complete the cleansing process, but it is quite simple and effortless. Why clean solar panels? The importance of solar panel cleaning allows for optimal efficiency of the Solar Home system to generate more energy for one’s household. Here are Buskowitz’s 4 recommended steps to keep one’s solar photovoltaic rooftop installation spotless:


Method 1: Use Air Pressure

Clean the soft dirt or dust-like substances on modules with air pressure.  If excessive soiling or dirt has piled up on the solar panel’s surface, brush the solar panel’s surface with a non-conductive brush or a sponge first.


Method 2: Dry or Clean with a Brush

Ensure that any brushes or agitating tools are constructed with non-conductive materials to minimize risk of electric shock. This also prevents the material from scratching the glass or the aluminum frame. Use an environmentally-friendly cleaning solution if you notice that grease is present on the solar panels.

Other tips to keep your solar panels clean:

  1. Refrain from scraping or rubbing the surface of the solar panel when dry, as this will cause micro-scratches on the glass’ surface. 
  2. The orientation of each panel matters. Request for your Solar Home system to be installed using diagonal mounting. This allows solar cells to be maintained and cleaned quickly as sediments will only accumulate at the bottom corner of each panel.
  3. Air dry or clean your panel with a brush every quarter to keep it clean.
  4. Finally, one may also request for a Buskowitz Energy Operations and Maintenance team to help with their Solar Home system’s quarterly housekeeping.

General maintenance and upkeep of a solar installation is only a small fraction of what it’s like to invest in a Solar Home system. Learn more and better understand your solar panel installation with other tips from Buskowitz Energy.

Wow!! Amazing blog. really great I think that I will also try this. Most solar panel providers will recommend that you clean your solar panels with water and a hose. Usually, it’s really that simple.

It sure was helpful when you said that you can keep your solar panels cleaned when you have them brushed every quarter. This must be the reason why the solar panels in my mother’s property ended up getting damaged. She mentioned that she failed to keep them clean and maintained. I will ask her to have them repaired by a professional and to do your tips moving forward.

I am very thankful that I found this post quite useful for my understanding of solar panels. From my perspective focusing on renewable energy generation is the need of the hour. And this blog certainly covers this essential topic. I hope those who are interested in harvesting solar panels and installing rooftops this post will give good subject knowledge on solar panels. Indeed, I too think of investing in solar and producing energy for the best side. Actually, I have been hearing about installing solar panels these days and this brings me to read your blog. Thank you so much for these beneficial inputs.

It was really useful when you indicated that having your solar panels brushed once every three months will keep them clean. My mother’s property’s solar panels must have suffered damage as a result of this. She said that she didn’t keep them maintained and tidy. I’ll advise her to get them fixed by a professional solar panel cleaning service and follow your advice going ahead.

Thanks for the advice about getting the solar panels installed diagonally so that the dirt and debris will only accumulate at the bottom part. We plan on having it installed at the slanting side of the roof facing the east. I’ll ask the professional to confirm if this is a good idea or if they have more effective options.

Thanks for pointing out that air pressure could be used to clean the soft dirt or dust-like substances on modules. This reminds me of my mother who is planning to have her solar panels serviced to keep them maintained next Monday. She does not have tools to use for the job, so I will ask her to hire a professional.
