A global analysis of solar car performance

The analysis, comparison and interpretation of raw solar car data

The 2021 Bridgestone World Solar Challenge Telemetry Challenge has been designed to allow for driving, testing and comparison of solar cars in the absence of a physical Bridgestone World Solar Challenge. The telemetry challenge will also allow registered analysts to engage with submitted solar car data, practicing and experimenting with analysis methods and presentation.

The success of the Telemetry Challenge and its method for data collection and analysis will be considered for potential future Bridgestone World Solar Challenge applications.

Solar Car Teams

Participating teams will compare solar car output data against one another in this friendly data collection experiment. There will be no winner - only the opportunity to display the hard work teams have committed to building their solar cars and test their efficiencies.

Teams have entered a solar car into the Telemetry Challenge that was either designed for the 2021 Bridgestone World Solar Challenge, has participated in past Bridgestone World Solar Challenges, or has participated in a past recognised solar car challenge.

Teams will drive their cars across two days and submit data collected whilst driving and charging at 60 second intervals. There will be no restrictions to how many times teams may stop for driver changes.

Day 1: At least 5 hours and at most 9 hours (car may then be recharged using only the car’s solar collector)
Day 2: At least 5 hours and at most 9 hours

Teams will collect the following data at 60 second intervals:

  • team identifier
  • timestamp
  • longitude and latitude (decimal degrees)
  • altitude (metres)
  • cumulative distance travelled (metres)
  • cumulative energy from solar collector (joules)
  • cumulative energy from battery (joules)
  • cumulative energy from external sources (joules, measured at the input to the charger).

The submission of following data is optional:

  • battery voltage (volts)
  • battery current (amperes)

Analysts

The Telemetry Challenge provides a rare and unique opportunity for members of the public to access solar car performance data. Solar car enthusiasts will have the opportunity to analyse solar car data output, compare performance, make commentary on data subsets and discuss with like-minded individuals through an exclusive forum.

Registered Analysts will gain access to the database from Friday 1st October. Analysts may then use test data to generate reports until Monday 26th October. This period will allow for experimentation and practice ahead of the live data playback.

A live data playback will take place as follows:

DAY 1
Data playback and analysis commences: 10:30pm Monday 25th October 2021 UTC
Data playback and analysis concludes: 7:30am Tuesday 26th October 2021 UTC

DAY 2
Data playback and analysis commences: 10:30pm Tuesday 26th October 2021 UTC
Data playback and analysis concludes: 7:30am Wednesday 27th October 2021 UTC

During this time, all solar cars' submitted data will be played concurrently. Analysts will assess, compare and comment on the data output in real time, comparing the data across cars as it plays simultaneously.

Written and live summaries of registered Analyst's commentary will be provided to the general public by Bridgestone World Solar Challenge Scientific Faculty members.

How can I watch along?

The general public are invited to read summaries of the data analysis taking place within the private analysis forum between 25-27 October 2021 via blog articles on the Bridgestone World Solar Challenge website written by members of our Scientific Faculty.

The general public are also invited to watch a daily Facebook livestream in which members of our Scientific Faculty will review the day's analysis discussion.

Facebook live discussions: 8:00am Tuesday 26th and Wednesday 27th October 2021 UTC
