Project Partners


CDTI has funded 125K of the SOLVIS  project. The SOLVIS project was ranked #2 out 110 proposals, and is considered a key demonstrator for green aviation / CleanSky technologies.  AERDRON was invited by CDTI to introduce the SOLVIS project during an Innoglobal aerospace industry lecture in December 2016.

SunPower USA

AERDRON & SunPower USA signed a project collaboration agreement. SunPower provided 106.5K of investment towards developing the SOLVIS UAV aircraft. SunPower has a proven track record with aviation related solar powered projects from the Solar Impulse II, NASA Helios, Google Heliostats, and others.

Embou MasMovil

AERDRON & Embou MasMovil signed a project collaboration agreement for the SOLVIS project. Embou MasMovil will provide the telecommunications and server infrastructure for flight testing in Aragon (Spain).

Battery Pack Development

AERDRON developed custom made battery packs for the SOLVIS UAV. The battery packs have individually fused 18650 cells. A bespoke PCB was designed for not only for providing power, cell voltage balancing,  but to provides I/O signals to servos, lights, and externals sensors. The SOLVIS carries (8) custom made battery packs in the wings. The SOLVIS can fly for 11 hours on battery power alone.  

Solar Array Development

The SOLVIS UAV utilizes SunPower Maxeon II solar cells. These are the same cells used in the Solar Impulse II. SunPower USA is a project partner on the SOLVIS project. The SOLVIS will use 96 solar cells to have a total available power of 328W. The solar arrays will be capable of charging the batteries after the night flight in only 3 hours. 


Since the SOLVIS has a large wingspan, the deflections and stiffness of the wing needed to optimized to not crack the solar cells nor couple with any natural frequencies. The wing design was performed using classical hand calculations, then verified using FEA. The SOLVIS wing and empennage was constructed from carbon sandwich skin construction with molded spars. The fuselage is made from molded carbon fiber shells.
