If using solar panel (with Stick Up Cam), should I choose "wired" mode or stick to "battery" mode?

Hey all. Just bought some Stick Up Cams (battery ones), with the solar panels. Fitted the first two a few days ago and all good (suggested solar charging), then noticed (perhaps the app got an update) that the app now sees the camera as powered by an "Electrical Socket" (I know that technically it is with the solar panel connected), and as a result it's suggests putting the camera into "wired" mode (not battery). I've done it on one of the cameras and now I have more options in the app, plus it seems to take more snapshots and I guess uses more power to be quicker at responding to motion events etc. My question really is, should you use "wired" instead of "battery" when using the solar panels, as obviously at night (and other low light times) the panels won't generate enough power so it will be using just the battery and I guess drain quicker? Anyone have any experience or advice please? Thank you!
