A question about solar panels

[Tink]

That would be the control module that "regulates" the power, commonly known as the "inverter". Original solar technology is a DC current panel system, routed through the inverter which converted the DC power into AC, or "normal" house current, and if off grid, switch between batteries and your house current. With technological advancement there are now micro inverters attached to the panel ( you now have a choice, but cannot mix) which are run through the inverter and into your home electrical panel. On homes with solar systems, you might notice another "box" nearby the main electric panel ( might be in their garage) about the size of a tankless water heater, that is it.

Are you a human being, or a human doing?
