Abstract: A solar tower system including an array of individually controlled carousel-type heliostats, where each heliostat includes a rotatable D-shaped carousel, a mirror array including horizontal, elongated flat mirrors supported in a tiltable (e.g., louvered) arrangement on the carousel, and a mirror positioning system that is disposed next to the carousel and controls the tilt position of each mirror and a rotational position of the carousel to reflect light onto a solar receiver. The heliostats are arranged in a closely-spaced (e.g., square or hexagonal) pattern that both maximizes the effective ground coverage ratio of solar power harvesting system and facilitates the formation of service pathways that allow access to any of the heliostats in the array (e.g., by aligning the straight peripheral wall portions of adjacent carousels in parallel with each other).

Abstract: A solar-tower system includes a raised solar receiver disposed on a tower and a mirror array including multiple flat mirrors for reflecting sunlight onto the raised receiver. The mirror array is disposed on a carousel-type platform that is rotatable around a vertical axis, and the raised receiver is maintained at a substantially fixed position relative to the mirror array for all rotational positions of the platform. A solar azimuth tracking controller controls the platform's rotational position to track the sun's azimuth angle such that sunlight shines on the mirror array from a fixed apparent azimuth angle at all times during daylight hours. Each flat mirror pivots around a corresponding unique axis, and a solar elevation tracking controller individually controls each mirror's pivot position to track the sun's elevation angle such that sunlight is accurately reflected onto the raised solar receiver at all times during daylight hours.

Abstract: A concentrating solar collector includes a solid optical structure a flat front surface, and PV cells and a micro-faceted mirror array disposed on the opposing rear surface. The micro-faceted mirrors are arranged in a sawtooth arrangement to reflect sunlight toward the front surface at angles that produces total internal reflection (TIR) and redirection of the sunlight onto the PV cells. The micro-faceted mirror array reflects sunlight onto the PV cells in an extended focus region of concentrated light that has a substantially uniform or homogeneous irradiance distribution pattern. The optical structure is a solid dielectric sheet either processed to include micro-faceted surfaces with reflective material formed thereon, or having a dielectric film including the micro-faceted mirror array adhered thereon. In one embodiment, three PV cells and four micro-faceted mirror arrays are disposed in an interleaved pattern with two side mirrors are disposed on side edges of the optical structure.

Abstract: A rotational trough reflector solar-electricity generation device includes a trough reflector that rotates around a substantially vertical axis. A strip-type photovoltaic (PV) device, or other solar-energy collection element, is fixedly mounted along the focal line of the trough reflector. A tracking system rotates the trough reflector such that the trough reflector is aligned generally parallel to the incident sunlight (e.g., in a generally east-west direction at sunrise, turning to generally north-south at noon, and turning generally west-east at sunset). A disc-shaped support structure is used to distribute the reflector's weight over a larger area and to minimize the tracking system motor size. Multiple trough reflectors are mounted on the disc-shaped support to maximize power generation. Flat mirrors are disposed at the end of the troughs to increase power in “hot” PV sections that are connected in series.

Abstract: A method for harvesting solar power by concentrating sunlight onto a raised solar receiver disposed on a tower. The method involves rotating a mirror array made up of multiple flat mirrors as a unit around a vertical axis such that sunlight shines on the mirror array from a fixed apparent azimuth angle at all times during daylight hours, and controlling each mirror's pivot position to track the sun's elevation angle such that sunlight is accurately reflected onto the raised solar receiver at all times during daylight hours. In one embodiment the mirror array is disposed on a roundabout-type platform whose rotational position is controlled to track the sun's azimuth angle and the raised receiver is maintained at a substantially fixed position relative to the mirror array for all rotational positions of the platform.

Abstract: A low profile heliostat with elongated louvered mirror segments is provided. Its envelope of revolution has the shape of a flat disc to enable heliostat fields with very high ground coverage ratio. The heliostat's disc-shaped footprint rotates around a substantially vertical axis (akin to a carousel). The short dimension of the mirror segments is drastically shorter than the disc's diameter. Embodiments are described in which the motion relies on two concentric rings, which are individually rotated around a vertical axis. The lower ring acts as a platform providing mainly azimuth tracking, carrying the upper ring. The differential rotation between the upper ring and the lower ring is translated into a rotation of the mirror segments around a second, perpendicular, axis and used for elevation tracking. Disc-shaped heliostat with D-shaped cut-offs are described, to facilitate the required maintenance access even in highly dense heliostat fields.
