The invention relates to a mirror module of a Fresnel Solar Collector System with a plurality of mirror elements pivotably mounted on a carrier plate and extending in parallel, which focus the sun light upon a receiver unit mounted above the mirror module in a raised position. The mirror elements are pivotably mounted on the carrier plate at least along longitudinal sections.

A solar energy collector system (32) has a fixed array (34) of reflectors (40) extending in parallel rows, and a common focal receiver (36) located above the fixed array (34) and extending parallel to the rows of reflectors (40). Incident solar radiation from all of the reflectors is reflected upon the receiver (36) which includes a heat absorbing medium adapted to absorb heat from the reflected radiation. There is an elevated support structure (38) for the fixed array (34) of reflectors and the receiver (36). The support structure (38) orients each row of reflectors at a respective fixed angle relative to the support structure. The support structure (38) is pivotally mounted to an upright elevation assembly (77) to allow controlled rotation of the fixed array (34) and receiver (36) simultaneously about a pivotal axis (39) extending parallel to the rows of reflectors (40) so as to track the movement of the sun.

This invention refers to improvements regarding transparent thermal insulation used to increase the performance of solar thermal collectors by reducing heat losses, to do this, superimposed layers of thermal insulating material are used and at least one of them is made of silica aerogel (7). These layers are located between the absorber (4) and the transparent (1) glass or similar material cover.

According to one embodiment, a solar heat collecting apparatus (1) comprises a first heat exchanging unit (22a) and a second heat exchanging unit (22b). The first heat exchanging unit includes a first pipe through which a heat medium flows (23) and a first heat receiving face which receives heat of sunlight reflected by a plurality of reflecting units (10). The first heat exchanging unit heats the heat medium flowing through the first pipe by using heat of the first heat receiving face. A second heat exchanging unit includes a second pipe through which the heat medium heated by the first heat exchanging unit flows, a second heat receiving face which receives heat of the sunlight reflected by a plurality of reflecting units, and a nozzle provided to the second pipe to discharge the heat medium flowing through the second pipe toward a back face of the second heat receiving face.

Foam backed solid support structure and trough solar energy collector. A support structure has foam or other polymeric material, a plurality of end arms, and a plurality of end caps secured to the formed foam material. The foam material is cut into a parabolic or semi-parabolic shape, and a reflective element may be placed onto the formed foam material and secured mechanically, with adhesion, and/or integrated with the surface. A solar energy collector formed using a polymeric core may have longitudinally-extending cowling, end caps, and end arms as described.

摘要:
Die Funktion eines linear konzentrierenden Solarkollektors beruht in einfachen Worten darauf, dass Reflektoren einfallendes Sonnenlicht auf ein von einem Wärme aufnehmenden Medium durchflossenen Receiverrohr reflektieren. Aufgrund der Erdrotation müssen die Reflektoren jedoch regelmäßig nachgestellt werden, um ein Eintreffen des Sonnenlichts auf dem Receiverrohr sicherzustellen. Bekannte Nachführungen verwenden hierzu errechnete Sonnenstände, was bei baulichen Abweichungen, etwa durch Dehnung und Materialbeanspruchung, zu Ungenauigkeiten und Effizienzeinbußen führt. Die Erfindung soll die Nachführung der Reflektoren in einem solchen linear konzentrierenden Solarkollektor verbessern. Dies gelingt dadurch, dass die Strahlungsintensität im Bereich beiderseits neben dem Receiverrohr gemessen wird und mittels einer Regelung bei ungleicher Ausstrahlung beidseits des Receiverrohrs die Reflektoren so weit nachgeführt werden, dass die Strahlungsintensität beidseits des Receivers gleich und damit das Maximum der Strahlungsintensität auf dem Receiverrohr liegt.

A protective transparent enclosure (such as a glasshouse or a greenhouse) encloses a concentrated solar power system (e.g. a thermal and/or a photovoltaic system). The concentrated solar power system includes one or more solar concentrators and one or more solar receivers. Thermal power is provided to an industrial process, electrical power is provided to an electrical distribution grid, or both. In some embodiments, the solar concentrators are dish-shaped mirrors that are mechanically coupled to a joint that enables rotation at a fixed distance about respective solar collectors that are fixed in position with respect to the protective transparent enclosure. In some embodiments, the solar collectors are suspended from structure of the protective transparent enclosure and the solar concentrators are suspended from the solar collectors. In some embodiments, the greenhouse is a Dutch Venlo style greenhouse.

摘要:
The present invention comprises an arrangement adapted for an absorption of primarily thermal and/or luminous energy arising from received sunbeams, and having a sunbeam-reflecting reflector unit faceable toward the sunbeams and a thermal and/or luminous energy-absorbing means related to the reflector unit, said reflector unit and said thermal and/or luminous energy-absorbing means being coverable by a transparent protection, said reflector unit, in particular the reflector surface thereof, being formed from a thin and easily bendable material. Said reflector unit and primarily the upper reflector surface thereof is adapted for a co-operation with a plurality of discrete support members, denominated “reflector spring”, distributed along a length-oriented or longitudinal extension of said reflector unit and the upper reflector surface thereof, and oriented perpendicularly to, or at all events substantially perpendicularly to, said longitudinal extension, in order to allow said reflector unit and/or reflector surface to, depending on a temperature influence, be able to deform within an elastic range applicable for selected shape and/or choice of material, however while keeping a profile of a stable shape.
