Keep the clean energy going with clean solar panels


Solar panels are a great renewable energy source, built to withstand constant exposure to the harsh elements. However, if not properly cleaned and maintained, solar panels may generate considerably less power. To ensure that your solar panels remain efficient, we’ve got some top tips on how to clean them.


DISCLAIMER: If you have not been trained or do not have the proper equipment to work at heights, contact your local professional to clean your solar panels for you.


Safety First

Solar panels are typically located on the roof, making cleaning a little more difficult. This is especially true when you introduce water to an electrical system. It is important to read and follow the procedure in your manual for shutting down the system before cleaning.

If possible, clean your panels on the ground with a soft brush and squeegee, or use a squeegee with a long extension and a fitted hose to reach the panels from the ground. Unless you have the right gear and training to do the job safely yourself, we recommend calling a professional. You can find one on LocalSearch.


The Perfect Time

An overcast day, early morning or evening is ideal when cleaning your solar panels. If the sun is bearing down on you while cleaning, the water will quickly evaporate and smear any dirt.

Early morning is particularly good as the dew that has settled on the panels overnight makes grime soft and easy to clean. This will also save you on water and energy when cleaning your solar panels.


Cleaning Frequency

clean your solar panels frequently

Solar panels should be routinely cleaned every 6 months. You can clean more frequently if you have the time. However, it’s important to consider that the more contact you have with the panels, the higher the risk that you may damage them. To avoid any scratching or abrasive markings, steer clear of scour pads.


Basic Maintenance

On top of cleaning your solar panels, you should also check other important elements to ensure you get the most out of your system. If you have trees blocking the sun from your panels, trim the branches to prevent shading. You should also check and clean the cabling and inverter for any dirt, grime or corrosion. Again, if you aren’t confident about doing any maintenance or cleaning on your system yourself, you can call a professional who will do it for you.
