A solar panel system for your home is one of your best investments. Because of this, you’ve got to make the most out of your system. Aside from monitoring your solar panel system, routine maintenance and cleaning will ensure it operates properly for a lot of years. 

Fortunately, solar panel cleaning and maintenance are not extremely hard. Almost every DIY solar user is able to handle maintenance by themselves. Oftentimes, it involves inspection of the batteries, electrical system, and wiring system. 

Today, we’re going to share with you some things you should know about solar system maintenance and cleaning. 


You will need to set up a routine battery maintenance schedule if your solar system has a battery bank. This will help keep the efficiency and lifespan of the batteries.  

The needs for your battery maintenance vary based on type. Most batteries require routine maintenance to stay in excellent condition. On the other hand, lithium-ion batteries need little to no maintenance. 

Here are some tips when it comes to maintaining your batteries: 

  • Cables and terminal connections need to be cleaned to avoid rust. 
  • Examine the stage of charge of your battery regularly. Every 3 months, you should apply an equalization charge to flooded batteries.  
  • Refill flooded lead-acid batteries using distilled water every 2 weeks or 1 month.  
  • Program voltage set points. 


This maintenance task refers to how your solar system is attached and what hardware is utilized effectively. They can be ground-mounted or roof-mounted. In addition to that, there are less popular mounts. This includes pole mounts and tilt legs. Before you pick, it is vital to think about the form of structure, cost, weather, and other aspects.  

For regular cleaning, you should check the racking for indications of debris buildup, damage, or loose hardware. You can do this once every 12 months.  

This task is a lot simpler if it is a ground-mounted solar panel system. However, you’ve got to ensure you wear the right protective gear if you’ve got a roof-mounted system. 

Electrical and Wiring 

It’s suggested that you check ground conductors, fittings, electrical conduits, and any other visible electrical system at least once every 12 months for security and indications of damage.  

Check cables or PV wiring. This will help ensure they aren’t touching your roof. Every PV wire needs to be fastened securely to the panel frame or racking.  


The climate of your region and your location greatly affects how often you need to clean the panels. Routine rainfall might be enough to keep your system clean if it is installed in your home.  

On the other hand, you might find that manual cleaning is required if there’s an accumulation of bird droppings, dust, or tree debris. If this is the case, all you’ve got to do is to rinse the panel using a hose. When wiping your panels, you’ve got to ensure you don’t use abrasive materials.  

You can always call an expert solar panel company if you aren’t certain of how to properly and safely clean your solar panels.
