Interesting that the cr2032 battery is not rechargeable, so is the solar panel real? Or does it bypass the battery and use the solar panel in lighted situations?

The guide should specify that the CR2032 needs to be rechargeable. They are readily available at a popular online shopping website. I was skeptical that the solar was real too, because of the frosted plastic placed over it. Based on the pictures in this teardown, and another video showing a red LED in the solar circuit, I conclude that the solar charging circuit is real.
