As the changelogs of the eufy security app are not that extensive, and frankly eufy could do more to keep us up to date on development of features and issues, I have decided to look into the Android app and compare 2.2.0 to the previous version.
In that context, I came across these settings and images for a solar panel:
<string name="eufycam_charge_mode">Power Source</string>
<string name="eufycam_charge_mode_battery">Battery</string>
<string name="eufycam_charge_mode_solar">Solar Panel</string>
<string name="eufycam_charge_mode_solar_tip">Please confirm you have installed the solar panel and connect it to the camera before changing the settings.</string>
