Best option for connecting a solar panel to T114?

Hello,

On the T114, there's a port for connecting a solar panel with an output voltage of "approximately" 5V (according to the Heltec documentation).

This solar panel port is supposed to be used to recharge the node's battery.

But the USB-C port also does the same thing, so can this USB-C port be used to connect a solar panel in the same way? Is it not recommended, and if so, why?

Thank you for sharing your experiences!
