maybe check dbus messages and see if you can differentiate between the two different power sources. if it is distinguishable, there might be hope.

I expect bad things to happen if you plug in a wall charger and do not put the solar panel under the sun at the same time. Or even without the charger, depending on how it is wired.
The reason is that the photovoltaic cells suffer when subjected to reverse voltage. Which means, if you connect the panel to a voltage source higher than the voltage produced by the panel itself.
So some sort of protection is essential. At least a diode if nothing else. This has been mentioned a number of times, for example here. Of course, your solar panel may have a diode built in, but I somehow doubt it.

13:48 < skvark> does someone know how jolla reacts if there are 2 chargers connected, another to the usb an another to the back power pins?
13:50 < Jonni> skvark: back power pins are disabled when usb cable is connected.
13:51 < Jonni> (and yes, I've tested it with my wireless charger toh)
And I'll add a diode there to be sure that nothing bad happens if the voltage gets reversed.
Edit: If there is a reverse protection already in Jolla, then the diode would be useless?

excellent! the pins are disabled when USB is connected. aaaaaaaah.
slightly off topic question: if the back power pins are disabled, will a TOH with a spare battery be impossible to charge when you plug in the wall charger? or is the reference in IRC only for input power pins?

How about printing the 2ndhalf so that there's an overhanging flap that covers the USB port when the solar kit is in use

(of course you need to design it so that it does not add to the existing battery but replaces it)
EDIT: And you have to glue a plastic pin like in official TOH's to the panel next to the battery so the microswitch will trigger. Won't charge without it.
Actually that's not true. It charges without the pin too. Hmm..
