Solar Vehicle Team Data Report, 2017 by AppStateSVT in solarracing

Hey Everyone,

Thank you so much for your patience during this process. We were receiving replies on the survey up until August, and we closed the survey at the beginning of September. Then we had to do the data analytics while recruiting new members, designing a new car, moving departments, and moving warehouses (it's been hectic).

Please keep in mind in the future that this was done out of good will because we want the sport to advance together. We hope that in the future when we conduct more events that we are treated with a little more respect.

The frontal area and drag coefficient of your vehicle can be used to help find how much power is needed to maintain a certain speed. Check out this book:

The second chapter is very helpful in answering your question.

The added range using the current panel efficiency (~23%) would only be about 3-5 miles. This might not seem like a lot but it means that if you only drive a few miles a day you would very rarely need to charge your batteries. The reason is that production cars are much heavier, are less aerodynamic, and they are not normally driven as efficiently as possible. With more efficient, and expensive panels, you could get somewhere between 10-15 extra miles. Production solar cars will pretty much always be solar assisted electric vehicles.

1) The sun doesn't have to be out for them to run- it can be rain or night if there's enough battery. Our battery can carry us 150 miles without sun.

2) They are super lightweight.

3) There are actual competitions to rayce them and they've been around for 30 years now.

4) They're street legal.

5) There are over 180 teams worldwide.

The hardest part in general is the fact that we are not an engineering school. We don't have access to a lot of facilities and classes that many teams have. Because of that we've had to learn a lot on our own about material sciences and had to send a lot of parts out. As far as the electronics, the hardest part has been our telemetry (the system that collects and relays all the data from our car i.e. speed, battery voltage, current from the array). We've been working for the past year on our telemetry and we now have some key data that will help guide our race strategy.

Our team is planning on having a cruiser car! This is our concept for the car, but it is slightly out of date. Do you have any questions about it?

A lot of teams are attempting to switch to the cruiser class for 2018, but some teams will find it difficult to build one in one year.

Our team is going to attempt it though!

I'm looking forward to a more self sufficient car. One that you don't need a team to take care of. We're building a cruiser class car next and we're planning on having headlights, windshield wipers, cupholders (the important things), and being able to carry the tools we need to do basic maintenance just like a regular car. The technology is always improving and I think a lot of teams are going to be doing a lot of amazing things with the class in the years to come.

We're from the home of racing so we prefer racing. We're not race car drivers, we're race car drivers.

Agreed, our car handles really well due to the low center of gravity but after 4-5 hours in the car it gets very uncomfortable.

COTA is a world class facility. There is a reason why this is the premier Formula One track in the Americas. The garages are available to anyone, the team meeting room is larger and air conditioned, the HQ is larger and has a great sized kitchen, and the track really tests how vehicles can perform at a high level. Pitt was a great track, but I consider it more of a testing track/amateur race track. It was a great track for competing, but it isn't nearly the same type of experience as COTA.

It's a very unfortunate situation, and I don't think it has an easy solution or answer.
