I should explain the rationale behind me using a solar generator. I am in the process of building a framework around my delta trike in order to fasten coroplast panels to it. The trike has a 500 watt bafang geared front hub motor and the left rear wheel is powered by me through a 58 tooth front chairing. I have made a few enclosed trikes and the big takeaway from that is the streamlining reduces the effort needed to maintain my usual speed which runs between 12 and 16 mph. That increases the range from using the front motor. I try to use MUP's and sidestreets as much as possible so the generator which is like I've said is quite small, roughly the size of a double height Kleenix box. It fits in the storage compartment behind me and will be used to power 4 LED penny sized turn signals and two 3" round LED tailights. The 60W solar panel fits on top of the storage compartment. The fact that if my charger is plugged into the 48V system it can add about 2 bars of power. Maybe even a bit more with the solar panels on a sunny day. I did test the generator on a roughly 80 km or 50 mile trip this past summer on my fat bike also a 48V system and it added 2 bars to the battery. Plus it is small enough to fit in the pannier used on that trip. One nice thing is only cost me $267 Canadian delivered to my door.
