    摘要: Zum Erkennen und Beurteilen von Verschattungen bei mindestens einem Solarmodul wird die von dem Solarmodul abgegebene elektrische Leistung erfasst; wird für jeden Sonnenstand am aktuellen Tag ein Erwartungswert der von dem Solarmodul abgegebenen elektrischen Leistung definiert; wird ein idealer Leistungsverlauf der elektrischen Leistung über den aktuellen Tag, der wolkenfreier Sonne ohne Schatten werfende Hindernisse über den ganzen Tag entspricht, durch Anfitten an Spitzenwerte der für einander entsprechende Sonnenstände erfassten elektrischen Leistung während einer Anzahl von vergangenen Tagen bestimmt; werden Abweichungen der von dem Solarmodul während des aktuellen Tages abgegebenen elektrischen Leistung von dem idealen Leistungsverlauf ermittelt; und wird für alle Sonnenstände, bei denen die von dem Solarmodul während des aktuellen Tages abgegebene elektrische Leistung unter dem idealen Leistungsverlauf bleibt, eine Verschattungswahrscheinlichkeit größer oder gleich null festgelegt, deren Höhe von dem Maß an Übereinstimmung der von dem Solarmodul bei dem Sonnenstand abgegebenen elektrischen Leistung mit dem Erwartungswert abhängt.

    摘要: A system for collecting solar energy using a plurality of energy collection elements arranged in a planar array within a stationary base structure, each comprising: an energy capture unit with optical means of focusing directional sunlight parallel to its axis onto one or more sunlight-to-electricity converters within itself, and means of sensing divergence of its axis from the sun's direction; and an angular positioning unit that orients said capture unit about two nested axes by slidably mounting two arcuate tracks in opposed and perpendicular arcuate slots, a convex track within said energy capture unit and a concave track within said base structure, each said slot equipped with a drive apparatus that engages its respective track and moves the positioner along it. The invention provides methods for determining the shapes and arrangement of such elements so as to maximize aperture efficiency while preventing collisions of adjacent elements.

    摘要: The present invention relates to a ham stand (1) that comprises a support structure (2) for a ham (3) and a base structure (4) for the assembly, and a connection element (5) of the support structure (2) with the base structure (4). The connection element (5) comprises a spherical joint (6) and a housing piece (7) of said joint (6) attached to the other structure such that it presents multiple degrees of freedom due to the combination of pivoting and rotational movements of the support structure (2) with respect to the base structure (4). Thanks to the pivoting movement, the user can rotate the ham to position it as desired in order to cut it conveniently and safely.

    摘要: The present invention offers an improvement to existing canting, slope error, and/or pointing measurement approaches, by using one or more cameras to observe the reflections of points of light in the firmament, such as the reflections of stars and/or planets as visible within the night sky in the heliostat facets. An illustrative heliostat measurement system comprises a plurality of heliostats, and at least one camera that observes at least one heliostat. The heliostats reflect an image of the firmament that can be observed by the at least one camera. The system further comprises (i) at least one captured image of the firmament reflected from at least one of the heliostats; and (ii) a computer comprising programming that determines a heliostat imperfection from the captured image, wherein the heliostat imperfection is selected from at least one of a slope error, a canting error, and a pointing error.

    摘要: A system and method for providing real time control of a heliostat array or CPV/PV module that reduces actuation cost, the disclosure reduces the fixed cost of calibrating and repositioning an individual surface. This simultaneously removes the core engineering assumption that drives the development of large trackers, and enables a system and method to cost effectively track a small surface. In addition to lower initial capital cost, a small heliostat or solar tracker can be pre-assembled, mass-produced, and shipped more easily. Smaller mechanisms can also be installed with simple hand tools and do not require installers to rent expensive cranes or installation equipment.
