Embodiment Construction

[0055] refer to Figure 1 to Figure 3 as well as Figure 5 to Figure 41 , these figures illustrate various components of a solar energy collection system according to various embodiments of the invention. The solar collection system includes one or more frames for mounting on the ground and a plurality of heliostats supported on each frame. A heliostat refers here to a device having optics configured to track the position of the sun. Thus, a heliostat may include one or more mirrors, solar cells, lenses, or other optical components. In the following examples, heliostats are described as having mirrors that track the position of the sun with actuators. Each mirror is movable in two directions (two-dimensional space) relative to the associated frame in order to track the sun throughout the day and redirect incoming light to one or more receivers (not shown). The receiver may include a tower configured with a boiler with one or more input apertures, a molten salt container, o...

Abstract

A solar collector system includes a plurality of frames. Each frame includes at least a pair of spaced apart side members, a plurality of cross members connected to the side members, the cross members pivotally moveable from a shipping configuration to a deployed configuration wherein in the deployed configuration, each cross member is positioned relative to an adjacent cross member with a predetermined angle, and a plurality of stantions extending from the frames. The solar collector system further includes a plurality of heliostats, each heliostat mounted to one of the stantions, and a plurality of ballasts coupled to the frames, each ballast having a lower surface contacting the ground without substantially penetrating the ground to maintain a position of the frames on the ground.

Description

Background technique [0001] Power tower solar collection systems typically employ a large number of mirrors supporting heliostats, which reflect sunlight onto the tower and in this way generate electricity directly or indirectly. Said heliostats are usually placed on the ground along concentric arcs at various locations around the tower. To avoid blocking between arcs, the distance between arcs is an increasing function of radius. To track the sun's position throughout the day, each heliostat is moved to a configuration that reflects sunlight toward the tower. Each heliostat is anchored to the ground by attaching to a sunken structure. This anchoring maintains the desired mirror orientation in windy conditions. [0002] In current systems, each heliostat is individually anchored to the ground by a structure sunk into the ground. Using ground sinking anchors, the installation of each ground sinking structure supporting the heliostats is time consuming and expensive. Also, ...
