A Brigham Young student team is working on their second solar-powered UAV. The first one, shown here, didn't have enough power to climb, but now they have better solar cells.

Here are the detail:

"Power system:
Mega 16/7/17 motor
MPJ 3.8:1 Gearbox
18x13 folding prop

Airframe:
Fuselage-Magellan E-XL
span-3m or 2m
airfoil-SD8000 

So we are just researching and trying to make a plane that will work. We currently have two wings being built.The high aspect ratio wing is the 3m which has a cord just big enough for the solar cell array. The low aspect ratio wing will have a chord length to fit two solar cells wide and span will be closer to 2m. 

Solar array:
24 A-300 cells
~3W per cell"
