Sunpower solar cells on hybrid e-bike with diffuse reflectors
Riding up a small hill on only 10 volts of solar power from Sunpower solar cells!
no batteries are used, just the power from the sun.
The highly diffuse reflectors provide the max solar output from indirect sun exposure ..
I just recently finished a 2 week e-bike trek through British Columbia, Canada. and I carried all 8 DIY Sunpower solar panels along for backup charging...the FEP or plastic protective top sheet on each panel has become scratched and visibly worn..
My motor is a 1000watt beast with heavy magnets, which is not ideal for really low wattage testing... so Im quite content with the results so far..
about the DIY panels..
8 panels with 4 Sunpower cells each
without reflectors or mounts, each panels weighs 100 grams each
- I have not weighed the whole kit, but I would make a guess of 5lbs or less.
about the hybrid e-bike
it is a mid-motor mount with freewheel cranks
The diffuse reflectors are a material named White97™ Film - donated by WhiteOptics
