This one was a seriously good example of just how much heavy lichen build-up can affect a solar system. ☀️
Before cleaning, this particular system was producing around 170W. After a thorough professional clean and removal of the heavy lichen, output increased to around 1,740W.
That’s a huge difference on this job.
It’s important to note that results like this are not what every solar clean will achieve.
But in this case, the panels were heavily covered in lichen, and the before-and-after figures showed a dramatic improvement once they were properly cleaned.
If your panels are covered in lichen or haven’t been professionally cleaned in a long time, it may be worth having them checked.
