Goal zero nomad probably the most popular solar units around for bicycle travellers because of their low cost and availability although customer service and longevity seems less than perfect.
Not ideal but it works.
Let s start with the worst case scenario.
Theoretically a good quality 12 volt 20 watt mono crystalline solar panel will produce approximately 14 volts at 1 3 amps under load so if you series wire up four 20 watt panels you ll have approximately 55 volts at 1 3 amps roughly about the same as a standard 48 volt e bike charger produces.

This design gives users a couple of advantages.
Sure there s a bit of an efficiency loss by first converting the 12vdc solar panel output into 110vac and then letting the e bike charger convert it back down to 48vdc but it certainly makes.
So we plug the panel into an inverter that then goes to the bike s charger inverter and finally to the bike s battery.
