Leaf build-up under panels
Leaves have been building up over the 10+ years since installation. I can still see light when sighting up under them, but barely. I was originally concerned primarily for the roof with the leaves holding moisture, etc., but I am now also aware that this is likely reducing our production and life of the panels. A study has shown that production decreases .2 to .5% for every 1°C increase in temperature. I have 33 panels in 3 rows. I'm wondering how others have cleared leaves from under their panels. My current thought is to get one of those leaf-vac/mulchers and attach a length of 2" or 3" pvc to the vacuum hose and use that to try to vacuum out the leaves. One concern I have is that there are some wires dangling down from the panels (not good, I know) and I wouldn't want to be damaging them in any way. Other ideas? Fyi, I and my neighbor took down some trees over these years, so there should be significantly less leaves coming on our roof than what there was earlier.
