FAQ
knowledge is power
Technically this is untrue, but you get the point.
Locations
Solar Rollers is growing rapidly. In 2019 we ran races in Colorado, Nevada and Texas. We are evaluating locations and will post 2020 race sites soon.
We also run a limited number of seed teams in areas we do not serve yet. Seed teams build a Solar Roller and use it to start a race in their area by recruiting more school teams and partners.
costs
The Solar Rollers program costs $2500 per team, including the materials kit, online course and race event. However, this cost is often subsidized by one or more regional sponsors.
For example, Tesla invested in Solar Rollers to reduce the cost for each first-year Nevada team to $500. Teams conduct their own fundraising efforts to cover their share of costs.
commitment
Here's what you need to participate.
a group of high-school-aged students who are stoked
an adult team-leader who is responsible and also stoked
a place and time to meet
about 40 hours of team time
You'll also want to confirm your team's availability for the all-day race event near the end of the school year.
As for tools, at a minimum you'll need to find or borrow basic power tools such as a drill, a jigsaw and a soldering iron. If you've got access to higher tech tools - use them!
RULES
The car specs and guidelines are left as open as possible to promote innovation. Rules are updated every year to keep things fair. Solar Rollers is an iterative program - high schools themselves push the technology forward every year while the energy-based racing challenge remains similar.
The Basic Guidelines:
Max length 100cm. Max width 55cm.
Minimum weight 900g.
PV cells must be protected with a covering of your choice.
Foam bumper protection required on front, rear and corners.
PV to battery voltage ratio is limited to prevent overcharging.
