Battery Charge so slow and if we can add a solar panel to it?

I got the Arlo Essential Video Doorbell wire-free recently. It took me few hours to have it fully charged. I am wondering if there is any accessories, like solar panel, so it can keep charging the device. I do not want to take the battery out and charge for hours, and the device cannot be function for few hours.

I doubt a solar panel option will be available but I'm sure additional batteries will become available at some point. Keep checking the accessories here.
