Solar Panels, do they need to be cleaned? 

Yes! We’re moving into the spring and summer seasons which means, pollen. There are a couple of do’s and don’ts when it comes to cleaning your photovoltaic panels. Let’s discuss the best way to clean and protect yours! 

Why is it important to clean your panels? 

Your solar panels are exposed to the sun to capture its energy. Pollen, dirt and debris can accumulate on your panels and actually decrease its absorption rate by 20% or more. This can lead to lower production and a higher power bill.  

Can I clean the panels myself? 

Yes, but safety must always be considered! Be sure to turn off your system before cleaning. Use non-abrasive cleaning materials. Avoid anything that could potentially scratch the surface like a brush with rough bristles. Avoid harsh chemicals such as bleach and inspect the panels to make sure you do not see any damages. Dish soap is okay to use but make sure it does not include moisture or fragrance, it will leave a residue. When done washing the panels be sure to dry off the water to make sure there is no left behind residue. The most important step, BE CAREFUL! That being said, you are always able to give us a call and we can get a trained service technician out there.

How often do I need to clean my solar panels? 

Generally speaking, your panels are pretty much set up and good to go. However, sometimes pollen, dirt, smog, and debris can wander onto your panels. Spraying water on them occasionally can help remove loose dirt but it will not be efficient enough long-term. If your home is near heavier polluted areas such as airports, construction sites or the highway may need more frequent care. A good practice would be to have it cleaned once every 6 months or a year depending on your home’s location. 

Quick Tips 

  • Do not pressure wash your panels to prevent damages or cracks 
  • Windex is a great glass cleaner for your panels 
  • Rain is not a suitable source of preventative maintenance 
  • Keeping your panels clean extends the life of your system 
  • Choose biodegradable soap and soft materials  
***All this being said, we highly recommend you hire a professional. But if you must DIY, be safe, don’t do it alone, and be careful!***
