I presume you're joking. The surface area of the entire airplane isn't even close to receiving enough power from the sun even if 100% of the energy it receives is converted directly to electric power. Solar cells convert only a small fraction of that, and that's not even considering clouds and night time.
Ah, well. I guess I'll go back to my work on designing a cell phone with a second port that can charge my laptop. That way, while my laptop is charging my cell phone, my cell phone can charge my laptop. I'll never have to plug either into the wall again.
