There’s no better feeling than seeing the energy bill from your utility provider go down every month from using solar power.

However, you must pay close attention to cleaning your solar panels to ensure they work to their full potential. If you’re not sure how to clean solar panels, we’re here to help.

Keep reading to discover home maintenance tips on keeping your solar panels in top shape and saving even more money on your energy bill.

Clean During Cooler Days

One of the best cleaning tips when cleaning your solar panel is to do it on cooler days for optimal efficiency. Too much heat can cause the panels to get too hot, reducing output.

Cleaning during cooler days will help to avoid such an issue. Firstly, it’s a good idea to check the manufacturer’s instructions for cleaning the panel, as every product differs.

After ensuring the panels are turned off, use a mild detergent and warm water solution to remove grime and dust from the surface. Once done, dry the panel and check for any potential damage. Cleaning your solar panel during cooler days can help ensure it functions at its best capacity.

Think About Your Safety

After installing solar panels for your home, please keep it clean and maintained. When cleaning solar panels, safety should be your top priority. Here are some things that you need to do before you start cleaning your solar panels:

  • Wear eye protection
  • wear protective clothing
  • wear gloves

This is crucial to minimize the risk of getting any chemicals or dirt in your eyes or skin. Do not use a glass cleaner or any harsh chemicals on your solar panels, as they may damage the photovoltaic cells and be hazardous to your health.

Before you start cleaning, ensure the area you are working in is well-ventilated. Make sure that your ladder, if using one, is secure.

Avoid harsh scrubbing as it may damage the surface. For more difficult stains, use a mild detergent and warm water. Take all necessary precautions, and don’t forget to always think about your safety.

Remove Dust, Leaves, or Dirt Using a Soft Brush

You should use a soft brush to clean your solar panels of dust, leaves, or dirt. You can start by using either a soft-bristle brush or a damp cloth to clear away any debris from the panels.

Be sure not to apply too much pressure when using the soft brush, as this could damage the panels. When working on the frames, use the brush to wipe away any build-up of dirt or stains.

After removing all visible dust, leaves, or dirt, use a hose to spray the panels lightly, and then use the brush again to remove any remaining dust.

After the panels have been sufficiently cleaned, use a dry cloth to buff and wipe the panels for a streak-free finish. Removing dust, leaves, or dirt using a soft brush ensures your solar panels are kept clean and in good working condition.

Use a Garden Hose

Using a garden hose is one of the best methods of cleaning your solar panels. It is quick and easy and does a great job of quickly and efficiently cleaning dirt, dust, and debris from the solar panels.

Ensure you are not too close to the panels with the garden hose. Otherwise, you may damage them. Use the spray pressure of the garden hose to help remove stubborn debris.

After cleaning, use a soft cloth to dry the panels. After cleaning your solar panels with water, check that all connections, vents, and seals are correctly in place. If everything looks good, you’re done and can enjoy the sight of your solar panels renewed and shining.

Monitor the Power Output After Cleaning

Once you’ve thoroughly cleaned your solar panels, the next step is to monitor their power output. This is best done with a voltage meter designed to measure the current output of the solar panel.

To use the meter, you’ll have to attach it to the solar panel’s output with the correct voltage settings and read the value that appears. If it’s below what it was before cleaning, you should check the connections and make sure they’re tight.

It may be time to call a professional for help if it’s still too low. Once you have a good reading, you should continue monitoring your solar panels’ output to assess their performance and ensure they stay as efficient as possible.

Consider Hiring a Cleaning Professional

Hiring a cleaning professional is a great option when considering how to clean your solar panels. Cleaning professionals know the most efficient way to clean and preserve solar panels.

They also typically use specialized cleaning tools designed for solar panel surfaces. Having a professional come in allows for peace of mind. They are skilled and know to take the proper precautions to ensure the job is done correctly.

Additionally, they often use solutions and cleaning products best suited for each panel to ensure the job is environmentally friendly and that no damage is done.

Lastly, a professional cleaning service is usually less expensive than doing the job yourself, and it will save time and hassle. Hiring a cleaning professional is the best choice for correctly and safely cleaning your solar panels.
