Although I am not a happy customer of Ring right now (as you can see by my posts over the last 2 weeks), I will tell you the Solar Panel is WELL worth the money. When I bought my spotlight cam, I bought an extra battery and the solar panel. I’ve had them connected to each other for a little over a year, and neither battery has ever been below 97%, even after extended periods of dreary winter weather. I would strongly suggest and recommend the solar panel and an extra battery for your cameras.
