A solar panel system includes solar tracking and dual locking hinges. A solar panel assembly may be connected to a base via a linear actuator, actuator arm, and lever arm, which in connection of either of the two locking hinges acting as an axis of rotation, form a toggle joint mechanism for tilting the solar panel assembly to a desired angle in a desired direction. The desired angle may be automatically determined using solar tracking algorithms using data from light sensors, or may be controlled manually by a user. The locking hinges may include electromagnetic locks, which may lock the associated hinge to the base when energized, and unlock the associated hinge when de-energized. To tilt the solar panel assembly in one of two directions, one hinge is locked and the other unlocked, allowing the unlocked end to move upward to achieve the desired tilt angle.
