The invention provides a device for unfolding solar panels 2, 3 for a spacecraft, which solar panels are connected with one another by an articulated axle 4, which in turn is connected with actuating devices for unfolding the panels by way of a tension device gearing provided with cable pulleys 11. An uncoupling mechanism, operative after unfolding of one panel 3, permits the articulated axle 4 to be separated from the tension device gearing. Upon swivelling of the unfolded panel 3 into an unfolded position, a pin 8, which is arranged in parallel to the articulated axle 4 engages in circumferentially extending grooves 12 and 12a. In this manner, the swivelled panel 3 can be guided to follow the solar altitude.
