Yes, but only on a trailer. To much shade and to little power otherwise

The way you mounted your panel it will die very quickly because of microcracks in the cells.

Which type of MPT charger to you use? I use Genasun chargers. They are very good, but also very expensive.

I used the MPT-7201A. It seems pretty common. 50 Watt panel output just about to marches the wall transformer provided for my 250 watt ebike conversion kit which is 29.4V 2A. Maximum I saw from the controller was around 27.8V 1.6A. The controller does try to track the voltage and current to maximize power output. To fully march the wall transformer rating, you would need a 75 Watt which is not a standard panel you can easily find and probably too large to have on the bike.

I have built a recumbent bike with front geared hub motor, 36V battery, 150W solar panel :D
Last summer I participated to the Sun Trip rally across France, Italy and Switzerland, I was able to get to the finish but I also learnt a lot!

This is the reason why for next year I am building a 'tilting trike' because I believe it is definitely more suitable for the installation of solar panels

Me? Maybe, depending on lots of factors. Like, does the vehicle have a roof anyway? What's the power that could be produced from a suitably sized panel versus how much juice does the the vehicle use? Is there any reason to have a separate power system for lighting and accessories (that could be used when the vehicle is propelled by muscle power, for instance)? Does the vehicle need to charge while it has no access to household power?

But generally speaking, it seems that onboard solar generation would be more trouble and expense, for less reward, than just using more battery and/or stationary solar charging.

The first e-bike I ever worked on was specifically designed with onboard solar charging. It worked as intended, though I suspect the solar charging system cost more than the rest of the bike.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.
