Solar panel re-designed
I wanted to build a solar panel with Sun Power cells @ under 100 grams ..
this is what I created .. a 12 watt solar panel @ 95.6 grams
8 / panels in total for 2013 SolarCross
###################################
After finally getting all the hardware in place this project took only a couple weeks to assemble a working prototype.
(1st prototype)
SolarCross 2012 pre-test build w/o sun diffuser
E-Bike Features:
Freewheel crank
5T motor sprocket driving a 80T sprocket
18 speeds / 1 small & 1 large sprocket upfront, and 9 gears on rear wheel
90% complete
24volt controller, 24v 750watt motor
6s1p 5000mah main LIPO battery
2x 4s1p LIPO 5000mah booster packs wired in series (SPDT rockers) with output from controller
Rider view
Emergency kill switch
Two booster pack switches and a third switch to test straight solar output to motor
4x DPDT switches to route solar output to batteries
4x volt meters to monitor 3 battery packs and solar output
Top meter is watt analyzer wired directly before the motor
Solar panels are hand built from aluminium angle and rivets, and polycarbonate. Designed to be super lightweight due to the 1000's of holes drilled to remove as much material a possible. Photovoltaics consist of 18x 6"x6" mono crystalline solar cells @ 3.8-4watts output each providing an est. 8.7volts (9v minus diode loss) and controlled to recharge any two cells from either booster packs and main pack.
The remaining 10% of the build entails installing the top sheet, a highly transparent lightweight FEP film (96%), and some wild nighttime lighting effects..
drivetrain demonstration (video quality is not that great)

small sprocket up front, can drive the bike without pedaling in the bike park, shown up to 0:55 mark then large sprocket for video remainder.
