I want to put together an E-bike that utilises solar energy. I thought the solar panel could be carried on a bike trailer behind.
Answers:
Yes it will. You would entail a very considerable trailer to be able to charge on the run. Watts / sq. ft. is very small. You would probably use more get-up-and-go than you get simply pulling the trailer.
A stationary system would work for re-charge, but it will take a long time unles a greatly large system. I have a small one about 2ft. by 2ft. on my boat. It be only flawless for keeping the battery charges between uses. It would pilfer days to re-charge it.
I guess you'd have a unyielding time getting enough power from solar panel to recharge an electric bike battery.
I've get an electric bike (use it to commute to work) and the charger supplies 24 Volts at 1.8 Amps (24 * 1.8 = 43.2 Watts) and it takes around 3-4 hours to recharge the battery after my 13 mile ride, so it requires something like 140 Wh (Watt-hours) of energy to recharge (that's smaller quantity than 2 cents of electricity, by the way).
Comparing to a solar panel from a small fountain, they provide on the order of 2 Watts of power - nowhere effective the 43.2 Watts provided by my recharger.

It doesn't take plentifully of energy to recharge the battery if you use a charger, but I think you'd requirement a pretty big solar panel to do the job.
If you can meeting the voltages, you may be able to do it. You would stipulation a controller for anything over 10watt solar panels.
