How To Clean and Maintain Your Solar Light or Power System

Since there are no moving parts to a commercial solar LED lighting or solar power system, maintenance is easy and doesn’t need to be performed often. However, even if your system is at a slope, the buildup of dirt and debris can still accumulate on the solar panels. There are a few things to do once a year to ensure the system runs at peak performance year after year.

Clean the Solar Panels

Cleaning the solar panels on any system is relatively easy and takes little time. Creating a solution of soap and water, using a soft brush and squeegee, will get your solar panels back to their installed luster. You need to do this early in the day before they start to really heat up from the sun. This is similar to washing your car, and with the steps below, you will be done in no time.


  1. After hosing off the panels to wet them down and wash away any loose dirt and dust, it's time to give them a thorough cleaning. Armed with a soft bristle brush and a mixture of soapy water, gently scrub the panels, paying special attention to any stubborn spots. If areas are particularly difficult to clean, don't be afraid to use your finger to apply a bit of extra pressure or let the soap soak for a minute or two before trying again.

  2. Once you've finished scrubbing, it's important to rinse the panels off thoroughly to ensure that no soapy residue is left behind. This can be done by using a hose or simply pouring water over the panels. Make sure to cover every inch of the surface, removing any remaining soap.

  3. To achieve a spotless finish, it's crucial to use a squeegee to remove all the water from the panels. This will prevent any water spots from forming as the panels dry. Gently glide the squeegee across the surface of the panels, starting from the top and working your way down. Take your time and be thorough to ensure a streak-free result.

Following these steps, you can effectively clean your solar panels and maintain their optimal performance. Remember, regular cleaning is essential to ensure that your solar power system continues to generate clean and efficient energy for years to come.


Other Maintenance

While you are there working on cleaning the panels, this is a great time to check all connections for any problems, such as chewed wires or conduit, and inspect the light fixture (if there is one) for any problems from weather, vandalism, or wildlife, and make any necessary replacements or repairs. Regular maintenance is crucial to ensure the longevity and optimal performance of your solar power system.


Inspecting the connections is essential to ensure that there are no loose or damaged wires that could affect the system's efficiency. Look for any signs of wear and tear, such as frayed wires or exposed connections. If you notice any issues, it is important to address them promptly to prevent any further damage.


In addition to checking the connections, it is also essential to inspect the light fixture, if applicable, for any issues. Extreme weather conditions, vandalism, or wildlife can sometimes cause damage to the fixture, compromising its functionality. Look for any cracks, dents, or signs of water damage. If you notice any problems, it may be necessary to replace the fixture to ensure proper illumination.


Furthermore, this is an excellent opportunity to replace the batteries if it has been five to seven years since their installation. Over time, batteries can lose their capacity to hold a charge, which can impact the overall performance of the solar power system. By replacing the batteries within the recommended time frame, you can ensure that your system continues to operate efficiently and effectively.


By incorporating these additional maintenance tasks into your routine cleaning, you can ensure that your solar power system remains in optimal condition. Regular inspections and necessary repairs or replacements will help maximize the lifespan of your system and ensure that it continues to generate clean and efficient energy for years to come.


That is all to cleaning and maintaining your solar light or power system. If you discover any issues, you can contact the manufacturer to troubleshoot the system further or purchase replacement parts.
