Is that a wood burning flu literally right next to the panels?!!
If so, yes I can see why you’d want to clean the panels – that’s a pretty niche setup!!

The Exit is 2m from the panels at the closest point in accordance with building regs. We only light the fire ~5 times a year and only burn VERY dry wood which has been stored inside the house. I’ve never seen any significant soot on the panels. Dirt? Yes.
We see about an 8% jump when they’re freshly cleaned, now whether this is just due to light getting to the panel or the ability of the panel to reject heat, I couldn’t say and it’s very difficult to tell how long that clean effect lasts due to variations in incidence, weather etc through the day.
Desert solar panels are regularly cleaned using either vibration, static or water.
