Earlier this month, we ran an article in regards to the Components Solar Grand Prix, a monitor race that additionally serves because the qualifier for the American Photo voltaic Problem, an overland race for school photo voltaic automotive groups. One of many cool issues about this 12 months’s race is that they added lessons for barely extra sensible vehicles to maintain the groups from straying as removed from automotive actuality as ordinary. In different phrases, they needed the vehicles to be a bit of extra helpful, giving further factors for extra seats.
After qualifying for the lengthy race, groups went onto a 1400-mile race that occurs in 4 levels over 8 racing days, together with numerous checkpoints and stops. In 2022, this implies it occurred over 10 calendar days. That may sound sluggish (many drivers can do 1400 miles in solely a day or two with regular vehicles), however when your solely energy supply is the solar, it’s a way more tough feat.
Now, winners are being introduced. The College of Minnesota Photo voltaic Car Challenge crew received first place within the Multi-Occupant Car class, whereas the MIT crew received the less-realistic single-occupant class. We haven’t heard a lot from MIT, however the College of Minnesota’s web site gave us extra details about their crew’s win.
The College of Michigan Photo voltaic Car Challenge has been competing within the American Photo voltaic Problem since 1993, however that is the primary time they’ve ever completed first, having come second each classes seven instances beforehand.
“Our crew has been at this for some time and we’ve had some unimaginable vehicles, however we’ve by no means been in a position to stand on high of the rostrum earlier than,” mentioned Amber Zierden, a U of M mechanical engineering pupil and the crew’s Director of Engineering. “There may be nothing higher than getting to construct one thing with your personal palms, after which after pouring 1000’s of hours into it, attending to race it throughout the nation with a few of your greatest associates.”
The scholar groups traveled greater than 1,400 miles alongside the Oregon Nationwide Historic Path from Independence, Missouri, to Twin Falls, Idaho, this 12 months. The competitors lasted 16 days in July and included 4 days of auto inspections, a bit of “Components Solar Grand Prix” race, and culminating within the eight-day journey throughout america.
College students on the College of Minnesota designed and created their very own motors for “Freya,” a photo voltaic automobile with two seats that may journey about 400 kilometers on a completely charged battery. The automotive’s 1,000-watt photo voltaic panel array prices a lithium-ion battery beneath it. The one crew on the contest who developed and constructed their very own motor, the crew’s onerous work paid off.
“Each Amber and I have been on the race final 12 months after we had the battery fireplace,” mentioned Ivana Truong, a U of M biochemistry pupil and the crew’s Director of Operations. “Over the course of the 2021-2022 faculty 12 months, I noticed how onerous our electrical crew labored to design and construct a wholly new battery and electrical system and the way all elements of the crew took what we realized from final 12 months’s race to make Freya extra ready for this race. I’m proud to be part of bringing dwelling first place for our entire crew, each previous and current.”
Freya suffered a deadly breakdown whereas ascending a slope in Raton Move, Colorado, in the course of the 2021 American Photo voltaic Problem (which was rescheduled from 2020 owing to COVID-19). This 12 months’s primary problem for the pupils was trekking one other hill — an almost 20-mile lengthy incline in Wyoming.
The scholars have already begun work on the crew’s subsequent automobile, which will likely be its fifteenth solar-powered vehicle. In Fall 2023, they’ll debut it on the Bridgestone World Photo voltaic Problem, the world’s largest photo voltaic racing championship, by which groups race all through Australia.
“It is a great success for our Photo voltaic Car Challenge college students,” mentioned Andrew Alleyne, dean of the U of M School of Science and Engineering. “What I discover much more compelling is the time, effort, and ‘sweat fairness’ that goes into one thing like this. The abilities, each technical and comfortable, that the scholars acquired all year long are issues that can catapult them to success nicely past what they realized within the classroom.”
Why This Issues
After we contemplate that photo voltaic racing hasn’t modified so much for the reason that Eighties (at the least on the floor), it’s straightforward to imagine that it’s a solar-powered highway to nowhere, however that couldn’t be farther from the reality.
As I identified in one other article a few crew from Arizona, the historical past proves in any other case. A photo voltaic automobile occasion in Australia, for instance, pushed GM to develop new EV know-how. They not solely received the race comfortably with their roly poly automotive (the Sunraycer), however this additionally led to GM creating the Impression, a prototype that ultimately grew to become the EV1. Even when the primary mass-produced electrical autos didn’t seem till a lot later, this was the primary time that trendy electrical vehicles have been on the highway in any vital numbers. Ultimately, GM returned the cars it had leased out and crushed them, however this sparked one thing else that just about nobody would contest:
Few individuals know that we began Tesla when GM forcibly recalled all electrical vehicles from clients in 2003 & then crushed them in a junkyard

Tesla’s preliminary years have been a battle, however the firm has since damaged by means of and proven that mass-produced electrical vehicles are possible, interesting, and even worthwhile. This put strain on different automakers to provide their very own electrical autos. Now we’re starting to see some vital progress being made by way of rising the variety of EVs on the highway.
In different phrases, yesterday’s seemingly meaningless photo voltaic automobile competitions have resulted in immediately’s electrical automotive revolution. They not solely proved the know-how out; additionally they disseminated data and experience to people who would go on to work within the area. Additionally they inspired others to take part.
Each participant in these competitions isn’t going to go on to be the subsequent Elon Musk, however most of them will change into invaluable gamers at some stage within the EV market. However, a couple of of them will go on to contribute to the trade that they wouldn’t have been in a position to make if it weren’t for his or her expertise engaged on a crew and getting stuff accomplished.
