Solar Panel Cleaning FAQs
Why should I clean my solar panels?
Anything getting in between the sun and the solar cells will impact the output of solar energy. Rain will rinse the larger debris off, however, we found that the #1 way to maximize the solar energy produced is by cleaning the panels.
Sunbridge Solar’s system is a low tilt (10 degrees) and it’s overall power reduction due to the 2017 Eagle Creek forest fire ash resulted in a -53% reduction.
How often should I clean my solar panels?
Cleaning frequency will vary depending on where you are located. For example, someone living closer to the road will accumulate more fine dust and debris, therefore, requiring more frequent cleaning. Furthermore, if your panels are angled at a low-tilt we recommend adding cleaning your solar panels to your yearly spring cleaning to-do list.
For high angled tilt panels, you may let Mother Nature take care most of the cleaning.
Is there anything special to do to remove forest fire ash?
While there is nothing special to remove ash, we highly recommend to clean off the ash ASAP. Ash is a thicker particulate and will severely reduce the solar energy output. To do this, simply wash the ash off with air or water. If fires continue, you might want to do a few more cleanings.
