Driver Compartment

The driver compartment, contained the our custom Dashboard PCB, and steering wheel PCB which was of course embedded in the steering wheel. As well as the Throttle and Brake Pedal sensors.

Solar Array

The solar array was a four square meter array consisting of 3 sub-arrays and 29 modules. producing over 1KW of power.

Communications/Wire Harnessing

All Custom PCBs and the MPPTs communicated with each other over CAN Bus. The main wire harness which connected all boards in the car consisted two four conductor shielded cables and use Molex Microfit connectors. The signals carried are as followed

• CAN High 1/2
• CAN Low 1/2
• GND 2x
• +12V Main
• +12V Supplemental
