Solar World solar cells on the 11-meter (36-feet) wings will provide a greatly enhanced endurance of eight hours, good for 1,120 kilometers (694 miles) with no reserve left in the airplane’s batteries.

The spreadsheet also shows that the airplane would be cruising on the equivalent of 398.15 miles per gallon at its best gliding speed of 63 mph
