Well if drone can fly by battery power why can't planes eventually
run
on batteries.

They already can. Just not for very long

Solar Impulse 2, did OK

Pity about the number of pax it can carry. Like none, zero, nada, ziltch.

How many pax could the wright brothers plane carry ?

Irrelevant to how viable solar power would be for a Dreamliner or A380
