A spacecraft comprises a main body; at least one elongated solar wing extending from the main body, defining a generally flat plane and comprising a pair of longitudinally extending side edges; at least one other component or structure extending from the main body and spaced at a separation distance from the at least one solar wing; and at least one solar trim tab coupled to the at least one solar wing, linearly elongated and extending in the generally flat plane in a direction transversely away from one of the longitudinally extending side edges, and sized and positioned along the longitudinally extending side edge for counteracting or compensating for one or more types of disturbance torques.
