I only had the items both solar panels and cameras direct from Ring in december 2019, they lasted 2 days as they were charging the cam batteries fine. Then all of a sudden on day 3 they stopped and Ring said all of the them needed replacing due to them being faulty and from what i recall (as i had to speak to so many different people) they said that the replacements will be fully checked and updated with the latest software so there will not be any further issues due to the camera not recongnising that there is a solar panel attached (the ring app had recieved an update that now showed something to do with a solar panel being attached, but on mine is was saying to add one rather than picking up it already had one attached). Not sure what that means as they should already update the firmware themselves.
