Abstract: A solar collector panel arrangement includes a plurality of panels interconnected to form panel wings which in turn are secured in a symmetric fashion to a spacecraft, especially a satellite. At least the axially outermost panels forming the tip of a panel wing, are partially and/or fully foldable while the other panels of the wing are fully unfoldable. In the fully unfolded state of a wing all panels are located in a common plane in which also the system central axis is located. The two solar generator wings are so folded and structured or arrestable in certain positions that the entire center of gravity in the partially unfolded state remains in the same position as in the fully unfolded state and in the fully folded state.
