摘要:
Heliostat facet configured from a flat structure comprising a central section (1) and a peripheral section (2) comprising first (3) and second sides (4), being both sections linked together by a plurality of arms (5, 6), which starting from the central section (1) radially run towards the peripheral section (2) taking as reference the geometrical centre (7) of the facet. In at least three of the arms (5, 6), there are support points (15) of the facet in the corresponding heliostat support (16). The arms (5,6) comprise first arms (5) which are arranged from the central section (1) to the peripheral section (2) running in a divergent manner and at least two couples of second arms (6) which starting from the central section (1) run to the peripheral section (2), the arms (6) of each couple radially running in a convergent manner.
摘要:
Pressure equalization between upper and lower surfaces of PV modules (14) of an array (12) of PV modules can be enhanced in several ways. Air gaps (32, 34) opening into the air volume, defined between the PV modules and the support surface (16), should be provided between adjacent PV modules and along the periphery (18) of the array. The ratio of this air volume to the total area of the air gaps should be minimized. Peripheral wind deflectors (20) should be used to minimize aerodynamic drag forces on the PV modules. The time to equalize pressure between the upper and lower surfaces of the PV modules should be maintained below, for example, 10-20 milliseconds. The displacement created by wind gusts should be limited to, for example, 2-5 millimeters or less.; For inclined PV modules, rear air deflectors (148) are advised for each PV module and side air deflectors (162) are advised for the periphery of the array.

Die Erfindung betrifft eine Befestigungsvorrichtung für mindestens einen Sonnenkollektor mit einem seitlichen Vorsprung oder einer Hinterschneidung im unteren Bereich des einfassenden Rahmens, insbesondere zur sogenannten Überdach- und Flachdachmontage, umfassend mindestens eine Trägerschiene zur Befestigung auf zugeordneten Dachhaken oder anderen Montagesystemen sowie mindestens einen in oder an einer Profilschiene geführten Kollektorspanner (1). Der Erfindung liegt daher die Aufgabe zugrunde, die sogenannte Überdach- und Flachdachmontage von Sonnenkollektoren zu optimieren. Gekennzeichnet ist die Erfindung dadurch, dass der Kollektorspanner (1) eine mechanische Anzeigevorrichtung (4) aufweist, welche das Erreichen der richtigen Position bei der Montage des Kollektorspanners (1) zwischen zwei Sonnenkollektoren signalisiert.
摘要:
A solar panel array is formed of a plurality of solar panels juxtaposed with one another along an array axis, and has a support element having first and second support terminations disposed substantially orthogonal to the array axis, with an unobstructed spatial region intermediate of the first and second support terminations. A vehicle transports the solar panels and has wheels arranged on opposing sides thereof. First and second track structures extend along the array axis and are coupled to respective ones of the first and second support terminations. The track structures each have an elongated portion for engaging and supporting respective ones of the vehicle wheels, whereby the vehicle travels along the tracks while carrying a solar panel, and at least a portion of the vehicle is disposed within the unobstructed spatial region. One of the tracks accommodates the wiring for the solar panel array.

摘要:
An anchoring device (30) for securing a mounting rail (20) of a solar panel (S) mounting system (100) to a support structure. The anchoring device (30) comprises: - a footing (31) to be rigidly fastened to the support structure; - a coupling member (35) for connection with the mounting rail (20); The coupling member (35) is connected to the footing (31) via a spacer member. The anchoring device (30) includes means for selectively varying the position of the coupling member (35) on the spacer member, thereby varying a distance or spacing of the coupling member (35) from the footing (31) to adjust or set an elevation of the mounting rail (20) relative to the support structure. The invention also includes a mounting system (100) for mounting one or more solar panels (S), comprising a plurality of elongate mounting rails (20) adapted to be arranged and secured spaced apart and substantially parallel to one another, wherein each of the mounting rails (20) is adapted to receive and support an edge region (E) of a solar panel (S) such that each solar panel (S) extends between at least two mounting rails (20) and a plurality of said anchoring devices (30) for securing each of the mounting rails (20) to a support structure, such as a roof structure.
