To generate electricity, the solar panel must be directly exposed to sunlight. Solar cleaning usually is not required unless you reside in an area where there is a lot of smog, dust, dirt, or sand blowing around. In most circumstances, a little rain now and again will suffice to keep your solar panels clean and free of debris that could reduce production.

There are expert choices for washing solar panels, much like car washes; your solar panel installation may even do it for you for a fee.

If you have a roofing network, it’s advisable to employ a cleaning service, even if it’s just for safety. Cleaning companies won’t do a faster or more thorough job than what you can, but they get trained to manage and sanitize rooftop units securely. When it comes to ground-mounted units, the service price may not be worth it once you can wash your panels efficiently and properly using a hose, dish soap, and a soft towel.

Bottom line

We all believe that rain cleans our solar panels. However, this is not the case. Because bird droppings and soot from surrounding facilities adhere to the panels, precipitation cannot wash them away. Washing solar panels will ensure that they are well-maintained.

Where you live determines how often you clean your solar panels. If you live in an area where there are no farms or manufacturing companies, you should clean your solar panels every two years. However, washing your solar panel twice a year is recommended if you reside in an active region.
