The Solar Impulse 2 (SB-SIB) is a proof-of-concept series hybrid (solar) motorglider developed from the Solar Impulse 1 (SB-SIA) for improved record-setting flight under solar power.

The easiest way to distinguish the two aircraft is by location of the motor nacelles: on Solar Impulse 1, the two motor nacelles on each side of the fuselage are far apart, whereas on Solar Impulse 2, they’re close together.

Also, the tail booms are distinctive: on Solar Impulse 1, the tail boom height is about 1/2 of the height of the fuselage under the wing, whereas on Solar Impulse 2, the tail boom height is about 3/4 of the height of the fuselage under the wing and the tail boom height is tapered aft.
