A rotary actuator has a rotatable platform rotatably supported on a base. The rotatable platform has a friction surface. An actuator band is operated by a band clamp so as to be selectively frictionally engageable with the friction surface. A motion actuator is coupled between the base and the actuator band such that change in length of the motion actuator causes corresponding movement of the actuator band. A brake band is operated by a brake band actuator so as to be selectively frictionally engageable with the friction surface, the brake band anchored to the base.

The present invention comprises at least two independently maneuverable panels, either reflective of photovoltaic, arranged linearly, and physically interconnected to at least one common control capable of moving the panels simultaneously. Each panel is mounted on a separate support allowing it to be pivoted from side-to-side and/or up-and-down independently of the other panels. The preferred embodiment will permit every panel in series to be moved in unison using two main cables. This apparatus is further designed to track the sun along two-axes-both side-to-side and up-and-down-while maintaining constant tension on these cables throughout all degrees of freedom permitted by design. The apparatus also permits each mirror to be focused independently on a smaller target by means of mirror warping.

Disclosed is an apparatus for a solar power generator as it relates to a portable and expandable solar power generator that can form a micro-grid power system comprising any elements described, either individually or in combination with any other elements, in any order.

A heliostat for tracking the sun is disclosed. The heliostat comprises a frame (104) with legs (102); an optical assembly (120) configured to hang between the legs of the frame by means of a plurality of wires (130); and a plurality of actuators (520) configured to change the orientation of the optical assembly via the plurality of wires. The optical assembly may include a mirror (122) or photovoltaic panel that tracks the sun, and concrete backing (610). The optical assembly may further include a tracking controller (150) to energize the plurality of actuators, photovoltaic cell (252) configured to power the tracking controller and actuators, cleaning assembly (1710), and reservoir (770) for capturing rain water on the optical assembly. The optical assembly may further include a camera (254) for capturing images of the frame and determining the orientation of the optical assembly based on the images.

A dual axis solar array tracker for supporting a plurality of solar energy harvesting elements at a plurality of solar collector nodes. Two perpendicular axes of movement, specifically a rotation axis at a rotatable transverse beam and a tilt axis relative to the axis of the transverse beam, enable accurate orientation in a stable configuration. The dual axis design of the solar tracker enables the movement of solar collectors such that they can be directed towards the sun wherein incoming solar rays are perpendicular to the solar cell element of the solar collector to optimize collection of solar radiation. The present solar tracker array also enables integrated solar, electrical and/or thermal energy cogeneration.
