Solar Panel Mount dimensions

I have several Ring devices, including one solar panel that is installed and working great. I have another camera (Stick-Up Cam v2) that I have mounted and I now want to put a solar panel near it. I have a section of wood on the side of the house that is about 2.5 inches wide.I cannot find the size of the mounting bracket for the solar panels. Can you porovide them, or a link to where they can be found?To clarify, the dimensions of the bracket that is screwed into the wood.
