A mounting bracket (320) for trapezoidal rib profiles is disclosed. This mounting bracket (320) includes an upper section (330) and a lower section (350). A first leg (352a) in a second leg (352b) extend from a lower portion of the upper section (330) in diverging relation to one another. Each of these legs (352a, 352b) is deflectable through a certain range of motion to accommodate installation of the mounting bracket (320) on a variety of different trapezoidal rib profiles.

A mechanical solar tracking and solar concentrating system having a Fresnel lens, moveable frame, track, retaining mechanism, and solar collector. The lens focuses solar energy at the collector; the frame holds the collector and lens, keeping them aligned as the frame rotates; and the track guides the frame to maintain a perpendicular orientation to the Sun. The solar collector receives the Sun's rays and the retaining mechanism releases, at established intervals, allowing the frame to rotate to the next location. The cycle repeats, tracking the Sun and concentrating its rays at a focal point, to generate temperatures at the focal point in excess of 500 C. These high temperatures can be exploited in several applications, such as producing drinking water from dirty water; cooking food; disinfecting medical instruments; accelerating fermentation of certain types of flora to produce electricity; generating work for generic purposes; etc.

Discussed are solar panel systems as well as devices and methods for mounting the solar panel systems to roofs and building structures. Catch clamp, mid clamp, and optionally end clamp assemblies can be preinstalled to the solar panels at the job site before placing and securing the resulting solar panel assemblies to the building structure such as a roof. After an installer places and secures a first solar panel assembly to the building structure, they can install each subsequent solar panel assemblies by attaching the leading edge of the subsequent solar panel assembly to the trailing edge of the previous solar panel assembly using a catch and catch receiver, hook and slot, tab and slot, or similar mechanism.

A drive arrangement is provided comprising at least one drive device, which is rotatable about a rotational axis, comprises at least one drive element and at least one retaining element, the drive element being arranged offset in the radial direction in relation to the retaining element, and at least one output unit, which is rotatable or pivotable about an axis, the output unit comprising at least one drive recess and at least one retaining recess, the drive element being associated with the at least one drive recess and engaging in the drive recess to drive the output unit, and the retaining element being associated with the retaining recess and engaging in the retaining recess to hold the output unit in a set position, the drive element having a cross section that is different from a circular cross section and that is curved at least in some sections, and/or the drive recess widening in the radial direction in order to define an entry opening for the drive element.

A mount for a solar panel capable of changing a tilt angle of the solar panel easily and positively, includes a tilted support frame including a pair of horizontal members extending along a horizontal direction in parallel with different heights and a pair of tilted members arranged between the horizontal members and extending in parallel to be tilted in one side, a fixed support member fixing and supporting the tilted support frame, a square-shaped panel support member on which a solar panel is fixed, a support shaft extending between the tilted support frame and the panel support member and supporting the panel support member to rotate, and a pair of stopper members respectively provided on both rotating end sides of the panel support member so that one end portions rotate freely and including engaging concave portions engaged with half circumferences of outer peripheries of the horizontal members.

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.

A solar-tracking photovoltaic array is described. The photovoltaic array includes mounting hardware configured to rotate photovoltaic modules associated with the photovoltaic array about one or more axes. In some embodiments, the photovoltaic modules can be coupled to a torque tube oriented in a substantially North-South direction. An orientation motor can then rotate one end of the torque tube in a manner that causes the photovoltaic modules to track the sun. The photovoltaic array can also include a locking mechanism that secures another end of the torque tube during times in which the orientation motor is not rotating the torque tube.

The lens focuses solar energy at the collector; the frame holds the collector and lens, keeping them aligned as the frame rotates; the track guides the frame to maintain a perpendicular orientation to the Sun; the solar collector receives the Sun's rays; and the retaining mechanism releases at established intervals, allowing the frame to rotate to the next location. The cycle repeats, tracking the Sun and concentrating its rays at a focal point, to generate temperatures at the focal point in excess of 500 C. These high temperatures can be exploited in several applications, such as producing drinking water from dirty water; cooking food; disinfecting medical instruments; accelerating fermentation of certain types of flora to produce electricity; generating work for generic purposes; etc.

A solar panel rail for mounting a photovoltaic module frame thereto is provided and has a rail body configured to for attachment of a rail bracket, an indexing flange located on the rail body and configured to box and maintain a module frame position along a short-side direction of the module frame, a tab located on the rail body and configured to hold the module in place along a long-side direction of the module frame, wherein the indexing flange and tab are configured to provide a predetermined locked in installation position of the module frame during installation thereof.

A securing fixture for a photovoltaic cell module that includes a first frame member that extends in a first direction; and a second frame member that extends in a second direction and is adjacent to the first frame member, the second direction being orthogonal to the first direction, the securing fixture being enclosed by a frame member having a corner portion formed by the first frame member and the second frame member. The securing fixture includes an abutting part that is fixed to a trestle and abuts on the trestle; and a holding part that holds the photovoltaic cell module, including a first protrusion that protrudes in a direction opposite to the abutting part, and abuts on an inner surface of the corner portion of the frame member, and a placing part on which the second frame member is placed.
