Solar panels are a great investment to save you some money on your electricity bills and also in making the environment sustainable. Nevertheless, to keep them efficient and have them functioning optimally, it is important to clean them on a regular basis. This guide will take you through the process of cleaning solar panels safely and effectively to derive the maximum benefit out of your solar energy system.
Why Clean Solar Panels?
You should know why solar panels should be maintained regularly before jumping into the cleaning process.
Maximize Efficiency: Dust, dirt, leaves, and bird droppings may collect on solar panels and prevent the sun rays from reaching the photovoltaic cells. This has the potential to lessen the amount of energy your panels produce.
Extend Life: Cleaning solar panels on a regular basis will help prevent accumulation of dirt that may cause permanent damage on the panels, including scratches and corrosion.
Aesthetic Appeal: Clean solar panels enhance the look of your home or business, particularly if they are visible to people on the streets.
When Should You Clean Solar Panels?
You should clean your solar panels regularly at the proper time to ensure they are in optimal condition.
Here’s when you should consider cleaning them:
Seasonally: Most only need to clean their solar panels once or twice a year.
Following a Storm or a High Wind:A storm or high winds can bring debris and dirt onto your panels. Washing them after such weather will make sure the dirt does not remain there long enough to affect performance.
If You Observe a Decline in Efficiency: In the event that you observe a decline in the production of energy, it could be because of the accumulation of dirt or debris. When that happens, cleaning your panels will restore their efficiency.
How to Clean Solar Panels: Step-by-Step Guide
The following will be required to clean your solar panels:
Step 1: Gather the Right Tools and Materials
Soft-Bristle Brush: A long-handled brush with soft bristles will assist you in cleaning off the dirt without scratching the panels.
Bucket of Water: Make sure you use a clean bucket of water, which is necessary to rinse the panels.
Dish Soap or Mild Detergent: A mild detergent can be used to loosen dirt and grime.
Squeegee or Microfiber Cloth: Use this to dry excess water and to provide the panels with a streak-free finish.
Ladder (as needed): You might need to use a sturdy ladder to reach your solar panels depending on the height of your roof.
Step 2: Ensure the Solar Panels Are Cool
Before you commence cleaning make sure you touch the solar panels to ensure they are not too hot. The cleaning process may destroy the panels if they are hot because of direct sunlight. The most appropriate time to clean them is in the morning or late in the afternoon when the panels are cool.
Step 3: Disconnect the Power (Optional)
Solar panels are generally safe to clean without having to disconnect the power, but it is always wise to switch off the inverter to avoid any electrical mishaps. You can normally do this by reading the manual of the system, or by calling a professional.
Step 4: Remove Loose Dirt and Debris
Clean solar panels with a soft-bristle brush or a long-handled broom to brush off the loose dirt, leaves, or other debris. Do not press too hard since it may scratch or break the panels.
Step 5: Wash the Panels
Take a bucket of clean water and add a little bit of mild detergent or dish washing soap. Wet the soft-bristle brush in the soapy water and rub the surface of the panels with it. Clean in small areas and ensure that you scrub all the areas to eliminate any accumulation of dirt or grime.
No Harsh Chemicals: Do not use harsh chemicals such as bleach or ammonia because they will damage the solar panels.
Avoid Abrasive Materials: Do not use abrasive sponges or steel wool that will scratch the panels.
Step 6: Rinse the Panels
Rinse the panels with clean water after scrubbing to remove all the soap and dirt. If you can reach your solar panels, you can spray them using a garden hose. Ensure that the water pressure is low to avoid damage. You may consider using low setting pressure washer.
Step 7: Dry the Panels
After the panels have been rinsed well, dry the surface with a squeegee or a microfiber cloth. This will assist in eliminating the water spots and will leave the panels free of streaks. Make sure that the edges of the panels are also dried to prevent water accumulation, which may cause corrosion in the long term.
Step 8: Inspect for Damage
Once you have cleaned your solar panels, check your solar panels to see whether there is any damage. Check cracks, loose connections, or any other factor that can interfere with performance. If you detect any problems, call a professional to check and fix your system.
Tips for Cleaning Solar Panels Safely
Do not Climb on the Roof: When your solar panels are on the roof, you should not climb up the roof without necessary equipment and safety measures. You can also hire someone to clean the panels.
Clean Regularly: Cleaning your panels once every six months or after a storm can help you prevent dirt accumulation and ensure your system is running effectively.
Professional: If you are not confident cleaning your solar panels or you have a big system, it is always good to hire a professional solar panel cleaning service to make sure that the work is done properly and safely.
