looking at the close up of the solar cells ..
i may be wrong but it seems there is already a dust build up on the flat solar panels

i would have thought that the solar panels would have been in a cone shape and below the rotors so that rotor wash blows off the panels every time its used
it would lower the efficiency of both the rotors and the cells .. but surely it would make it last a lot longer

anyone want to try an experiment as to the effect of a cone below the rotors on a quad to see what changes in thrust and stability it creates
we could even test for optimal .. ie generation v thrust effects

Actually, due to the boundary layer, dust doesn't blow off surfaces nearly as easily as you think.

Get your supercar all dusty then blast along the highway at 300Kph and it'll still be covered in dust afterwards.

What they should have done is put the panels at a bit of an angle so that vibration would have helped the dust slide off -- but even that wouldn't help too much.

I know... they should have put the panels on the bottom facing down! :lol: :lol:

sloped panels
anti static coating
vibration
air flow
all would have helped
but a flat panel on top that appears to have clumps of dust on it already is the last design they should have used
yes the boundary layer would make it difficult to completely clean the panel .. but it would carry way less than the baseball mit to catch it they are using now
i cannot see why the whole body was not made as a cone shaped solar panel and used as the external structure as well as the panel support
it would be more vertically stable as well

having the trailing edges impregnated with micro hairs ( quieter flight like an owl ) and hinging the lower set of rotors so they gently brush the cone when they fold down when landing may also help
