Junction box and solar cell array

A solar cell array, comprising:

• a junction box, including:
• a plurality of solar cells interconnected in multiple strings;
• and
• a junction box arrangement, including:
• a bottom part and a separate top part mechanically connected to the bottom part, and first contact elements in one of the bottom part and the top part, some of which are connected in the installed state to the solar cells and two of which are connected to a connecting cable of the solar cell array,
• in the other one of the bottom part and the top part, second contact elements which are interconnected and electrically contact the first contact elements and connect them to one another in the installed state, are situated,
• an actuator for releasing the mechanical connection between the bottom part and the top part, for completely separating the top part from the bottom part and for disconnecting the contact between the first contact element and the second contact element, and
• a control unit for generating a control signal for the actuator assigned to the actuator at the input side.
