Learning how to properly clean your solar panels is crucial if you want your system to function optimally. Plus, regular cleaning can help you avoid unnecessary damage to your panels and keep them looking their best for years.
Below, we've listed the most important steps to take when cleaning your panels.
1. Check the manufacturer's instructions
Check the manufacturer's instructions first. They list specific steps to follow to clean a specific solar panel brand. Following these instructions will also help you avoid unnecessary damage to the panel.
Also, make sure to turn off the solar panel system before cleaning. The manufacturer's instructions should tell you how to shut down the system.
2. Removes loose dirt and debris
Next, remove any loose dirt and debris from the panel. Dirt and debris can build up quickly, making the panels less efficient at generating energy. Use a leaf blower or soft cloth to remove most buildup before cleaning the panels.
In winter, you may need to learn how to remove snow from your solar panels. Learning how to remove snow from solar panels will make it easier for you to clean them thoroughly and allow more sunlight to hit them.
Also, be sure to protect yourself when you climb on the roof. This means wearing proper work clothes, non-slip shoes, and most importantly, using a fall arrest system.
This is an immediate (and necessary) preventive method to avoid serious accidents.
3. Spray with water
Next, spray the panel with water to remove more dirt, dust, and debris.
However, do not use high-pressure water jets or water jets for this step. A powerful water jet can damage the panel. The force behind the high-pressure water jets can also make it easier for you to lose your balance. Use a light-pressure hose or bucket.
As you learn how to clean rooftop solar panels, you can clean them more thoroughly by going on the roof. But be careful - water can make the roof slippery. Always wear safety gear when cleaning the panels on the roof.
Learning how to clean ground-mounted or wall-mounted solar panels is easier than roof-mounted solar panels. You can lightly spray or hose them with water, but again, don't use high-pressure water from a sprinkler or jet.
4. Use a scraper
After cleaning the panel with water, use a scraper to remove excess water. This step is especially important if you have hard water (i.e. water rich in minerals) because it prevents mineral buildup.
If available, use a squeegee with an extended handle. This way, you can remove water from hard-to-reach areas, whether your panels are mounted on a roof, wall, or ground.
5. Avoid abrasive products
Finally, avoid abrasive products. Harsh chemicals or itchy sponges can damage your panels and make them less effective. Even some cleaners can damage your panels.
To keep the solar panels effective, use only water, a soft sponge and a soft cloth when cleaning.
