I fitted a solar panel ( proper Eufy one 2.8 watt ) couple of days ago but forgot to change mode from battery to solar panel until today. When I first plugged the panel in ( on top of a ladder LOL ) i noticed the blue ‘charging’ led flashing on face of camera, not wanting this to draw attention to the camera i stuck a small piece of black tape over the led. I watched the battery level for a couple of days and % stuck at 85%, the animated battery level was moving when sun on solar panel, but no increase in %. Today I investigated changing mode to solar panel in the app, the animated charging icon went away, went back to the non-moving display just showing bars and a % and a small solar panel icon appeared next to it in power manager. will monitor the charge % for a few days, one thing I did find out though, by switching the power mode to solar panel in the app it stops the blue charging light on the camera flashing. One thing that did occur to me, it is not good to keep lithium batteries at 100% charge, so maybe solar panel will stabilise % at a lower level to protect battery.
EDIT - a couple of hours of decent sun today ( after turning the mode on camera power mode to ‘solar panel’ last night ) and the % charge has gone from 85% to 89%… PHEW, glad of that, with the camera plugged into solar panel with power mode on ‘battery’ the % actually dropped from 88 to 85% over a couple of days…
