Are you talking about the World Solar Challenge that has run 15 times since 1987, including last year?

https://en.wikipedia.org/wiki/World_Solar_Challenge

GM/Aerovironment won the first year at 41.57 mph average...not too shabby. Most years were at least that good, many were faster. Speed is very dependent on the weather, of course. The best speed was in 2005 by Eindhoven University of Technology at 63.7 mph average. You may have heard of them.

There is now a Cruiser class with cars that are a bit more practical.

The winning 2019 team are now working on a production version.

" I remember watching a similar thing at Laguna Seca decades ago, but I think most of the bikes were still gas powered to see who got the most miles per gallon. "

I can see some kind of fold out accordion style solar array bike cover for charging.

Good luck with that. Do the people who think up stuff like that have any idea how long it takes to recharge a motorcycle-size battery using solar cells of a size that are typically installed on a home roof? And if they are thinking that you only need sunlight to power a motorcycle and do not need a rechargeable battery then I hope all of their travel is downhill.

You gotta love politicians for their ability to make new technology sound so simple and easy. "

" Haha! You're welcome. It's fun and I can remember a lot about how my build made me feel, even though I never got to V2.0.

Good luck!

It's a great setup I've used on a few builds, and sold to multiple customers. It's pretty easy to set up and wire. You made a good choice.

Simple and robust once you take the time to wire it up neatly.
Also I've had email exchange with Ian (Hooper) who's the man behind it and he's both responsive and helpful.
I have done same email exchange with him (Ian Hooper) as well which is a huge support for this setup. I'll keep that in mind and bounce ideas off of you when I get to that point.

Do you have a build you've documented by chance? "
