| Solar Kit
For Great Dane, Trailmobile, etc. This conversion kit (shown for a 53-foot dry van) includes a rooftop solar array, electric drive (bogie), electric control unit, and cabling. Electric motors assist the diesel tractor, providing additional 5Hp (elec). On level runs, this solar assist can provide a 15% fuel saving. Cost for a large van is typically $35K and time for investment return is approximately 12 years at 1999 fuel prices. |

| In other large van applications, the solar power can be used for refrigeration assist, for powering traveling exhibits, or for powering electrical communications. | Some small van applications: solar power can be
used for powering electric gardening tools(blowers, hedge trimmers, etc). Batteries can be added to provide surge power for starting motors and for storing excess solar energy. |

Electric Bogie
The electric undercarriage (or bogie) provides traction on one axle. Two AC electric motors provide torque proportional to sun intensity. When the truck is going downhill or stopping, the motors, acting as generators, provide additional (dynamic) braking.Some of the electricity generated during dynamic braking is used for night lighting assist, for a small additional fuel saving. |

Solar Array
Solarex photovoltaic arrays on the roof provide DC power to a DC-to-AC drive motor inverter. The arrays add 2 inches to the van height. |
| Electrical Control
Electrical controls include the motor drive inverter, that is installed on the trailer underdeck, and the driver control box, which connects cab to trailer via a breakaway electrical connector. |
