Our aim is to fly at higher altitudes than Solar Impulse/SkyDweller, which keeps us above the turbulent winds and cloud cover of the troposphere, and makes long endurance flight more reliable/less weather dependent. Our platform is also a lot smaller than SkyDweller, which helps keep costs much lower and opens some interesting new opportunities - for example, deploying lots of aircraft in a mesh network.
The Solar Impulse/SkyDweller lineage is very inspiring - what an amazing way to demonstrate how much you can do with solar power!
