Hello everyone i am on a high school solar car team. We raced 2 years ago in the dell/winston solar car challenge witch is now the hunt/winston solar car challenge as dell no longer sponsors. We had a very simple car aluminium frame and some motorcycle parts with a small etek motor about 12 hp at 48v so we had 4 optima blue top lead acid batteries.
Now this years race is getting closer. We are working carefully with a university team that offered up the mold for a carbon fiber body with a titanium frame. Our current issue is Batteries and motor w/controller. In the last car it was a non issue the rules limited are batteries and funds limited are motor.
Now the university team that gave use the mold used lithium iron phosphate with a Kelly motor and controller.
I would like to know what this forum has for ideas with various other makes and models of motors and batteries. Im also wondering how i can put the power from the solar array back into the batteries as im drawing power away to drive the motor.
I cant list of a lot of numbers but i do know this
I have been stumped on this for a few weeks looking around for the answerers this forum seems to have a wealth of information on all things that can be and have been made electric.
Thanks

- The finished car should be around 600lbs.
- This race is a lap race who can do the most laps in a week on a track.
- The car will be made to be street legal but only in Texas. (as an experimental vehicle)
- I have specs on the solar cells that we already poses. LINK we have 1000 of the individual cells in these panels.
