Solar Car Equipment

Constructing an API STELR solar car from the kit

A  video has been produced to show you how to construct the API STELR Solar Car. Thanks to power engineer, Jarman Stephens, (2014 API Bursary holder) and videographer, Thomas Cotter, for producing the How to Build a Solar Car video.

You can also access a PowerPoint presentation giving step-by-step instructions to construct a basic solar car.

Changing Gears on the API STELR solar car

A new video has been produced showing how to change the gear configuration for your API STELR solar car. It is the second video in the series produced by Jarman Stephens and Thomas Cotter. We suggest students only work on changing the gears once they have constructed and tested their car.
