A full panel these days (with an active transponder) easily draws over 2
amps.
The current you'll actually get out of the solar panel would not make a
significant difference. You'd be more likely to notice the additional
drag
due to the turbulence than you would notice a benefit in the electricals.
If 36 AH of batteries (with a generator on your engine) isn't enough,
you've
got other problems.

Is that the generator attached to the spare bike pedals for something to do
when the pilot gets bored? 8-)

But more seriously, would the material of the canopy absorb the frequencies
used by the solar panel - if not, would there be a problem with mounting the
panel inside the 'glass'. Even mounted outside, I suspect that the joint
around the canopy would cause sufficient turbulent layer that the extra
'roughness' would not be noticeable, if the panel were to be mounted behind
the canopy.
