The supplied power supply unit provides the standard USB-C 5 volt, 1 ampere. If your solar panel provides this, it should work. However, the camera does not have a battery, so it needs constant power. Charging is therefore not an option. You can of course connect a battery in between and then charge it with the solar panel.

It should be noted that the power cable is permanently connected to the camera, i.e. there is no plug connection on the camera side.

Supplied with power via usb-c. I cannot judge whether solar works.
