Solar surface steering system and hydraulic actuator

A solar surface steering system comprising:

• a solar surface;
• a base mount;
• a main body including:
• a first rotary vane actuator configured to rotate the solar surface via a first rotating joint;
• and
• a second rotary vane actuator configured to rotate the main body of a hydraulic actuator via a second rotating joint connected to the base mount;
• a fluid mover operably connected to each of the first and second rotary vane actuators and configured to actuate the first and second rotary vane actuators;
• and
• a control system electrically connected to the fluid mover and configured to control operations of the fluid mover,
• wherein the first and second rotary vane actuators are affixed to each other and positioned such that a rotational axis of the first rotary vane actuator is orthogonal to a rotational axis of the second rotary vane actuator, and
• the first rotating joint is connected to the solar surface by a first plurality of supports, wherein the solar surface is rectangular and each corner of the rectangular solar surface is connected to a respective first support of the first plurality of supports and the first supports from opposite sides of the rectangle join at the first rotating joint;
• and
• the second rotating joint is connected to the base mount by a second plurality of supports, wherein the base mount is rectangular and each corner of the rectangular base mount is connected to a respective second support of the second plurality of supports and the second supports from opposite sides of the rectangle join at the second rotating joint.
