A solar cellconverts solarenergy to electrical energy

Photons in sunlight providethe energy that moves

electrons from one layer of asemi-conducting metallic

wafer to another The movement of the

electrons creates a current.

BODY & CHASSIS

The main goals in designing the body

are to minimize the aerodynamicdrag

Minimize weight, and maximize

safety.

A space frameuses a welded or bondedtube structure to support the loads andthe body

The semi-monocoque or carbon beamchassis uses composite beams andbulkheads to support the loads and isintegrated into a non-load bearingcomposite belly pan.

A monocoque chassis uses the bodystructure to support the loads.
