The present disclosure concerns a panel capable of bending under the effect of a load and having a peripheral surface provided with a plurality of pivoting attachment devices; each attachment device comprises: a metal gripping member adhered to the peripheral surface of the panel; and a metal clip cooperating by interlocking with the gripping member and configured to allow the gripping member to pivot when the panel bends.

The present invention relates to a solar evacuated heat collecting panel for collecting solar energy and more particularly, to a solar evacuated heat collecting panel having a heat absorbing plate and a heat medium circulating tube mounted therein so as to withstand external stress by means of a glass window structure and to minimize loss of solar energy collected therein. The present invention provides a solar evacuated heat collecting panel for collecting solar heat to obtain energy, the solar evacuated heat collecting panel comprising: a case made of glass or a metallic material; a glass window mounted on the upper portion of the case so as to form a space together with the case; a heat collecting portion comprising a heat collecting plate seated inside the case and the glass window and at least one heat medium circulating tube attached to the lower portion of the heat collecting plate by brazing welding and mounted so as to penetrate one side of the case; a side spacer made of a metallic material so as to connect a edge of the glass window and a edge of the case to each other; an inner spacer that penetrates the heat absorbing plate so as to support the case and the glass window at a predetermined interval; and an evacuating tube mounted on one side of the case so as to evacuate the interior of the panel.

A support assembly for supporting one or more photovoltaic modules on a support surface, such a generally flat roof, is disclosed herein. The support assembly includes a ballast tray configured to accommodate one or more ballasts; at least one tubular member coupled to the ballast tray, the at least one tubular member configured to support one or more photovoltaic modules above a support surface; and at least one clamp member coupled to the at least one tubular member. In one or more embodiments, the support assembly further includes at least one channel member coupling said at least one tubular member to said ballast tray. A mounting system including a plurality of support assemblies is also disclosed herein.

An energy collector is disclosed. The energy collector contains an absorber and a working fluid. The working fluid is held in a state of two-phase equilibrium to minimize sensible heating and thus heat losses to the environment. The energy collector may be held under a vacuum to further prevent heat losses to the ambient environment. One or more energy collectors may be connected to other energy collectors, end uses, or thermal energy storage.

A frame enhancer may include a body, a first extension extending from the body and including a first notch, a second extension extending from the body, and a third extension extending from the body and including a second notch. The first extension and the second extension may define a first slot. The second extension and the third extension define a second slot. The first slot may be configured to receive a first side of a support arm, and the second slot may be configured to receive a second side of the support arm. The first notch may be configured to lock the first side of the support arm in the first slot, and the second notch may be configured to lock the second side of the support arm in the second slot. At least a portion of the first and third extensions may be configured to support a flange.

An octahedral space frame includes a first plurality of double octahedral structures disposed in a first row in a longitudinal direction, adjacent ones of the first plurality of double octahedral structures sharing two common members. Each of the first plurality of double octahedral structures includes respective first and second single octahedron structures joined in a transverse direction and sharing three common members, the transverse direction being orthogonal to the longitudinal direction.

A frame enhancer may include a body, a first extension extending from the body and including a first notch, a second extension extending from the body, and a third extension extending from the body and including a second notch. The first extension and the second extension may define a first slot. The second extension and the third extension define a second slot. The first slot may be configured to receive a first side of a support arm, and the second slot may be configured to receive a second side of the support arm. The first notch may be configured to lock the first side of the support arm in the first slot, and the second notch may be configured to lock the second side of the support arm in the second slot. At least a portion of the first and third extensions may be configured to support a flange.

The invention relates to a new way of stabilizing and mounting solar panels in the form of conventional heat exchangers comprising a trough and a glass cover or of a photovoltaic panel on house walls with the aid of frames made of natural or artificial stones which are made break-resistant using fiber materials and are stabilized in such a way that the panels are also break-resistant on impact and can be mounted as self-supporting structures on a wall; furthermore, the panels in particular satisfy high standards in respect of esthetics and are low-maintenance and thus permanently appealing. Multiple solar panels comprising stone frames can form entire stone-solar panel facades.

The present disclosure describes an expandable splice configured for reinforcing a tube of a solar owner system, the splice including a top panel, a bottom panel, a first side panel, a second side panel, and at least one beveled corner panel, wherein the first and second side panels are connected to the top and bottom panels either directly or by the at least one beveled corner panel to form a channel therebetween.
