5watt ring solar panel

Hi guys, Just wondering has ring stopped producing the 5 watt solar panel for spotlight cam in europe. Based in ireland and currently have the 2watt solar panel with the spotlight camera. This setup is useless here, the charge produced by the solar panel is not enough to mantain the battery let alone recharge it. It did charge up last week when we had two sunny days so not a fault with solar panel. Being ireland most of the time it is overcast especially in Winter. I would imagine the 5watt panel might have some hope of keeping the battery charged. Thanks, Carl.
