APEGGA Presentation Nov. 3, 2005 The Team Over 100 students:

APEGGA Presentation Nov. 3, 2005 Solar powered vehicles Utilize solar power as a source of power for moving the vehicle (generally photovoltaic cells) Utilize solar power as a source of power for moving the vehicle (generally photovoltaic cells) Must be designed to be extremely energy efficient due to limited power availability Must be designed to be extremely energy efficient due to limited power availability Onboard energy storage used as a buffer Onboard energy storage used as a buffer –e.g. flywheels, batteries, etc.

APEGGA Presentation Nov. 3, 2005 Solar Car Design Rules Car must be no larger than 1.8m wide, 5m long, and 1.6m high Car must be no larger than 1.8m wide, 5m long, and 1.6m high Solar cells determine Class Solar cells determine Class Battery weight is limited depending on battery technology Battery weight is limited depending on battery technology
