   Testing this flexible solar panel for the electric bakfiets roof, looking at 20-50W realistic rate with sub-optimal exposure and a lot of clouds, it's a 100W panel. With the 1.6lb box it's 5.2lb, probably 10-12lb by the time I have a stiff enough roof mounted, (articulated?) and charging the bike battery. What should I make the roof out of?

     The trike certainly takes care of the stability concerns, check out this solar velomobile

     if you're using a proprietary e-bike battery like bosch or shimano, you may have to use an AC charger and batch swap between two batteries, but you should expect to use more than you charge, so that's not as useful as a range extension when only collecting 10-50W.

     The bakfiets roof would be in front of me (and it already has an aluminum frame that might hold up the panel.) So, it wouldn't be as high and wobbly as this build ended up. Shade for me would be nice but I'm torn between it being a rain roof vs tilting to give better shade / get better solar.
