PRAXIS GREENLIGHT 7
The Praxis Greenlight 7 solar powered drone is illustrated below. The drone has a flight duration of up to 7 hours (weather conditions permitting); much longer than others presently on the market. It is due to come into production by March 2018.
Its modular payload system is designed for the one platform to suit differing customer needs, such as:
- Public safety, law enforcement, and border protection
- Mapping and mining
- Agriculture and pastoral
- Medical deliveries to isolated or remote communities
- Environmental and conservation management
- Maintenance inspection of utilities
- Outdoor media and sporting events.

SOLAR WING SETS
Encapsulated Solar Wing Sets
Praxis has an in-house aeronautical design capability. We design and build to order specific solar powered wing sets for ‘retro-fitting’ on electric powered drones or for newly designed (by us or others) drones.
