What are the technical challenges?

Our design challenge is coming up with a lightweight fixed-wing UAV with a relatively high aspect ratio for soaring at stratospheric heights.

The aircraft design should also allow for maximum efficiency across all technical aspects including batteries, MPPTs and flight performance.

Both photovoltaics (PVs) and battery technology are evolving rapidly and in time to come solar planes will be able to execute complex tasks that drones of today can achieve but, with better flight endurance.
