The High School Solar Car Challenge this month

I have been persuaded to cover the (High School) Solar Car Challenge this year, as well as my regular university teams. Solar car racing is even more impressive when the teams are from high schools!

The 22 high school teams listed below (in five divisions) will be racing at the Texas Motor Speedway this July 15–22 (with Covid protocols in place). The race will also be live-streamed via the event’s YouTube channel, or check out    and    (click on the icons). Best of luck to all the teams!

Classic Division

For these more basic cars, no hub motors may be used, and solar modules must be have a rated efficiency of 20% or below. Batteries must be lead-acid. Cars in this division typically weigh around 450 kg.

  • Holy Solars from Kent School, Kent, CT racing The Solar Schell, a new car (also a new team). The car weighs 318 kg, with 17.9% efficiency panels.
  • KCAL Solar Crusaders        from Keller Center for Advanced Learning, Keller, TX racing Deus Volt, a new car (also a new team). The car weighs 463 kg, with 17.4% efficiency panels.
  • Kentucky Solar Cats    from Bath County High School, Owingsville, KY racing Appalachian Spirit, a new car. The car weighs 392 kg, with 19% efficiency panels.
  • NTCA 7 Solar Car Team from North Tampa Christian Academy, Wesley Chapel, FL racing The Solar Stroller, a new car. The car weighs 360 kg, with 18% efficiency panels.
  • WASP (Women’s Air Service Patrol)    from Ballard Memorial High School, Barlow, KY racing Miss Fifinella, a new car (this new all-female team is named after these women, who were the equivalent of British “Atta-girls” – see this news story). The car weighs 450 kg, with 19.7% efficiency panels.

Advanced Classic Division

This division is like the Classic Division, but is for schools that have participated in the event three or more times before. Cars in this division typically weigh around 350 kg.

  • Covenant Christian Academy    from Covenant Christian Academy, Colleyville, TX racing Cougar Spirit, which also raced in 2019, coming 3rd in the division (one of two cars from this school). The car weighs 310 kg, with 20% efficiency panels.
  • LISA Academy Solar Car Team    from LISA Academy North Middle High School, North Little Rock, AR racing SolEater, a new car. The car weighs 1000 kg, with 19% efficiency panels.
  • MISD Shine Runners    from Ben Barber Innovation Academy, Mansfield, TX racing Black Widow, a new car. The car weighs 318 kg, with 19% efficiency panels.
  • Prosper Mighty Engineers    from Prosper High School, Prosper, TX racing Apollo, which also raced in 2019, winning the division. The car weighs 300 kg, with 18.9% efficiency panels.
  • Wylie East Solar Car Team      from Wylie East High School, Wylie, TX racing East Beast-Xtreme, a new car. The car weighs 226 kg, with 20% efficiency panels.

Advanced Division

This division is for more sophisticated cars. According to the regulations, teams may use a hub motor, solar cells with a rated efficiency above 20%, prefabricated solar car molds, and other battery types. The list price for all bare solar cells must be less than $10/watt; teams may pay extra for cutting, tabbing, or lamination of cells. If teams use prefabricated solar car molds, the body constructed from those molds must be made by the team (i.e. the mold can be donated by a university team, but not the entire body). Batteries may be of any chemistry type.

Cars in this division typically weigh around 250 kg, which is roughly the same as cars built by university students for the American Solar Challenge.

  • All Saints’ Solar Car      from All Saints’ Episcopal School, Fort Worth, TX racing The Car, a new car.
  • Covenant Christian Academy    from Covenant Christian Academy, Colleyville, TX racing Cougar Pride, which also raced in 2019, coming 2nd in the division (one of two cars from this school). The car weighs 220 kg, with 22.2% efficiency panels.
  • Iron Lions      from Greenville High School, Greenville, TX racing Invictus, a new car (one of two cars from this school and an attractive catamaran; see this news story). The car weighs 195 kg, with 24.7% efficiency panels.
  • Oregon Solar Car Team      from Bend Schools, Bend, OR racing Lumidos, a new car (an attractive symmetric four-wheeler). The car weighs 181 kg, making this the lightest car this year, with 24.3% efficiency panels.
  • Plano Green Team    from STEAM Engine, Plano, TX racing Mark 2, a new car. The car weighs 320 kg, with 17.5% efficiency panels.
  • RAHS Green Energy Team      from Raisbeck Aviation High School, Tukwila, WA racing La Cucaracha, a new car (an attractive catamaran). The car weighs 227 kg, with 22% efficiency panels.
  • Staten Island Solar Car      from Staten Island Tech HS/Green Technology Club, Staten Island, NY racing High Energy #5, which also raced in 2013, 2014, 2015, 2016, 2017, 2018, and 2019. The car weighs 227 kg, with 23% efficiency panels.

Electric-Solar Powered Division

This unique division is for two-seater electric vehicles powered by a stationary solar battery-charging station (i.e. the solar panels are not on the cars). The solar array on the battery-charging station must be no larger than 5 meters by 1.8 meters, with solar cells at most 19% efficiency. Cars in this division also typically weigh around 250 kg.

  • Coppell Solar Racing Team        from Coppell High School, Coppell, TX racing Outlaw III, which also raced in 2018 and 2019. The car weighs 250 kg.
  • The Heroes’ Alliance Vehicle Technology Team from Heroes’ Alliance, Detroit, MI racing The Blurr, a new car. The car weighs 250 kg.
  • Iron Lions      from Greenville High School, Greenville, TX racing Regulus III, which also raced in 2019, winning the division (one of two cars from this school). The car weighs 290 kg.
  • Western High School Solar Cats        from Western High School, Davie, FL racing E-Cat, a new car. The car weighs 296 kg.

Cruiser Division

This new division is for four-seater vehicles. Person-mile scoring is used.

  • Prosper Engineering Team from Rock Hill High School, Frisco, TX racing Esther, a new car. The car weighs 350 kg, with 22% efficiency panels.
