Abstract: A method for measuring a shape of a reflector surface of a heliostat at night using a bright star at different elevation and azimuthal settings according to an embodiment of the current invention includes setting the heliostat in fixed orientation such that aberrated and overlapping star images formed are translated due to Earth's rotation in a translation direction across the heliostat array receiver; viewing images of the bright star using a fixed array of cameras placed at or near an array receiver of the heliostat, wherein each camera of the fixed array of cameras has a large aperture lens, and simultaneous exposures are made quickly enough and repeated for long enough, so that, as they translate past the cameras, the aberrated star image is fully sampled in two dimensions, and wherein every point on the reflector surface of the heliostat appears in one or more of the recorded images as being bright from reflected starlight; and processing the recorded images from the fixed array of cameras with a data processor to obtain the surface shape by integration of the surface slopes.

Abstract: Thermal energy storage systems and methods that include near-black body concentrated sunlight receivers disposed in thermal storage media for storing sunlight and extracting thermal energy for multiple end-use applications. The concentrated sunlight receivers are characterized by absorption of sunlight of at least 95%. The thermal energy storage systems are modular and transportable and can be scaled-up in capacity. Solar concentrators may be integrated with the thermal energy storage systems.

Abstract: The present invention relates to optimizing power generation of solar trackers. In embodiments of the invention, the optimization may include raycasting solar panels that are near each other and backtracking one or both of them depending on the raycasting results. Such optimization may reduce or eliminate shading of the solar trackers at certain times of day, even solar trackers installed on sloped terrain.

Abstract: A method of determining and responding to an overcast sky condition during daylight hours in a solar tracker installation utilizing a single, fixed-position irradiance sensor associated with a set of solar tracker assemblies of the solar tracker installation and, if a series of irradiance levels communicated by the irradiance sensor to an array controller of a solar tracker control system of the installation indicates that an overcast sky condition has been present for a predetermined overcast sky duration period, the array controller transmitting control signals to a set of solar tracker controllers associated with the set of solar tracker assemblies to deviate from a normal solar tracking mode to an overcast sky mode by pivoting respective tables of the associated set of solar tracker assemblies to one or more predetermined overcast sky condition angles of inclination, and a solar tracker control system for implementing the foregoing method.

Abstract: A photovoltaic tracking method and apparatus, a tracking controller and a photovoltaic tracking system. The method includes: determining an advance adjustment time instant between a previous preset adjustment time instant and a next preset adjustment time instant; obtaining a target tracking angle of a tracking bracket corresponding to the next preset adjustment time instant; and adjusting an angle of the tracking bracket to the target tracking angle in a case that a current time instant is the advance adjustment time instant, wherein the angle of the tracking bracket remains unadjusted at the previous preset adjustment time instant and the next preset adjustment time instant. In this application, the power generation of the photovoltaic module is increased in the time period from the previous preset adjustment time instant to the next preset adjustment time instant, thereby reducing the power loss of the photovoltaic power generation.

Abstract: 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.
