After a light skim, this seems like a good match; the land/area isn't used for much else anyway and since PV installations are usually devoid of humans and engines it wouldn't be a bad idea to roll this out on a larger scale.
Absolutely agreed, I am struggling to think of many downsides. Maybe some wasps or bees start a nest near a panel meaning it's difficult to clean the panel? Hopefully the nest gets left alone & the efficiency lost is tolerated, to let the bees/wasps live.
even if they had to clear the ones near the panels it sound slike a huge bet win
Panel cleaning can be done by robots, no?
I expect in 10-20 years most panel cleaning is done by robots similar to window cleaning robots, with small ramps allowing the robots easy traversal over the whole installation. The technology is directly transferable from vacuum robots and window cleaning robots, with the added benefit of knowing the geometry in advance.
