Morphology
The compound is compositionally derived from 'wall' (vertical surface) + 'panel' (a shaped piece or control surface), so its basic meaning — a panel on or attached to a wall — is directly inferable. While the definition specifies an electronic control/interface, that domain-specific nuance does not block comprehension of the core concept for a B1 learner who knows both constituents.
Etymology
Wall panel for controls comes from the idea of a flat board of switches and buttons, a panel, fixed on a wall so people can press or turn them. Think of a box on the wall with buttons to change lights or heat, so it means 'a wall-mounted control unit'.
