Why Do I Need To Clean My Solar Panels?

Solar panel cleaning is important as it will remove any dirt, dust or debris that may have accumulated on the surface. This will help them to work more efficiently and promote their longevity.

Dust and dirt is often not a major issue, as the sun can still penetrate through it and will mostly be washed away by rain. Though after some time rain may cause marks and dirt build-up on your PV solar system that will need to get cleaned up frequently.

Leaves need to be removed regularly because they'll build up or trap more dust, which may affect the solar panel efficiency. Along with any bird droppings that may have accumulated over time, which can be prevented with bird and critter proofing guards.

By regularly cleaning your solar panels you will not only keep the condition of your system in top shape, but it also protects and preserves your warranty.

How Often Should I Clean My Solar Panels?

You will want to clean the panels at least once a year (some manufacturers recommend twice), depending if you live in an area with frequent wind, rain, snow, or hail storms.

The position and angle of your solar panel system should be taken into consideration when deciding how often you should complete any solar panel cleaning. The more horizontal your PV panels are the more likely they are to get dirty and collect debris, which will have an impact on how much energy you will generate.

You should be assessing the condition and cleanliness of your solar panel cells regularly.

If you notice any rusting on the brackets that hold them in place, sagging from being out of alignment, dirt build-up, or a lot debris has accumulated - it might be time to get yourself some appropriate solar panel cleaning equipment!

How Do I Clean My Solar Panels Properly?

After attracting the sun all day solar panel cells can get very hot, therefore it is advised that panel cleaning or assessments on your system should be done in the morning when it is likely to be less hot.

Even on cool days you should still be cautious of any solar cleaning, as they are partially made of glass and constantly attract the sun, so touching them could burn you.

If the PV system is dirty, it is best to use tools or equipment that are Eco-friendly, have been created to protect the environment, and will not damage your solar cells or the ground in your garden. Using just a hose and some soap or other household cleaning products may not be efficient enough.

How Can I Be More Eco-friendly When Cleaning My Solar Panels? 

It is best to opt for solar panel cleaning products that are considered "environmentally friendly" as they will not contain harsh chemicals that have the ability to harm the environment or wildlife.

In some cases, a professional may be needed to apply the cleaner and then rinse off everything to avoid any chemical spills or leaks into the ground.

You should ensure all equipment and cleaning solutions are cleaned or disposed of appropriately and safely, to ensure you do not damage or leak toxic substances into your system which can be harmful in various ways.
