A floating body includes a main body having first and second surfaces opposite to each other and a first side surface connecting the first and second surfaces and first and second joining parts located on the first side surface to be opposite to each other in a first direction parallel to a ridge line defined by the first surface and the first side surface. The first and second joining parts each include a first portion located on the first side surface and a second portion connected to the first portion to face the first side surface. End portions of the first and second joining parts face each other. A minimum distance between the end portions is greater than twice a width of the second portion in the first direction, and is smaller than a minimum distance between the first portions of the first and second joining parts.

A monolithic trim piece is used for covering an opening between the edge of a photovoltaic module and the roof. The trim piece, with a curved front face, is attached to the underside of the photovoltaic module(s) using a standardized end-clamp (for a single module) or a standard mid-clamp (for a pair of modules). A threaded fastener with a T-shaped head can be used in a recessed channel located underneath an attachment flange of the trim piece.

Systems and techniques for boltlessly supporting and securing solar modules are disclosed. For example, in an aspect, a system features a support structure including a support rail, and a frame including a plurality of rails each having a slot to receive a solar module therein and a bottom plate to boltlessly couple to the top surface of the support rail via one or more boltless mounting components. A boltless mounting component may include a post operative to interlock with an insertion hole for securing the frame to the support structure. Moreover, a locking pin may be disposed through a pin hole on each of the top surface of the support rail and the bottom plate of the frame, where the locking pin advantageously maintains a predetermined alignment and advantageously provides a shared electrical ground connection between the support rail and the frame.

A photovoltaic mounting structure includes a frame for holding a photovoltaic array including a plurality of widthwise channels so as to permit photovoltaic modules to be easily slid between pairs of the channels, the photovoltaic modules resting upon flanges of the channels. In various embodiments, domed protrusions are disposed on lateral sides of the channel to prevent kinking of the modules and reduce friction, retention teeth are formed on upper surfaces of the flanges to position the modules; locator teeth are formed on lower surfaces of the flanges to guide the channels to predetermined spacing; and pre-installed mounting clips are attached to a top surface of the channel. The mounting clips each include an anti-rotation tab oriented downwardly and partially disposed in a corresponding hole in a top surface of the channel so as to prevent rotation of the mounting clip when a bolt of the mounting clip is rotated.

Disclosed is a system and device (10, 100, 200, 300) for mounting a solar panel (11) to a roof (43). The device (10, 100, 200, 300) allows for the mounting of solar panels (11) with various thicknesses using an end clamp (12) and base (13) assembly where the end clamp (12) is height adjustable along an alignment portion (20) that projects vertically upward from a planar top surface (19) of the base (13). The end clamp (12) includes an end portion (18) with a three-angle bearing surface (27) that engages both a side surface and a groove (23) within a side surface of the alignment portion (20). The solar panel (11) frame is secured from the top by an upper clamping surface of the end clamp (12) to the alignment portion (20) and the top surface of the base (13).

A roof comprises a solar radiation heat recovery device that is invisible from the outside. The roof is made up of supports receiving a heat transfer network which has a longitudinal groove designed to receive the male profile of the protrusion of the heat recovery modules. The supports comprise arms which exert a lateral pressure on the flexible network. The resilient deformation of the network permits the sliding thereof between the arms to the clamped position. The groove of the network closes around the protrusion, immobilizing the module and holding the assembly in the support fixed to the roof frame. The roof is particularly intended to recover solar radiation heat in a way that is aesthetically pleasing, economical, simple and easy to install.

A solar thermal collector and an accessory structure of a building are provided. The solar thermal collector includes at least one heat absorbing plate and at least one heat insulating plate. Each of the heat absorbing plate includes at least one first slab and first engaging parts connected with the first slab. Each of the heat insulating plate includes at least one second slab and second engaging parts connected with the second slab. The first engaging parts are respectively engaged with the second engaging parts, and a gap is maintained between the first slab and the second slab to define a heat collecting channel, through which a heat transfer fluid flows between the heat absorbing plate and the heat insulating plate. A heat conductivity of the heat absorbing plate is at least 30 times greater than a heat conductivity of the heat insulating plate.

A concentrating solar collector module includes improvements in performance and assemblability. In one configuration, the module includes a reflector having a reflective front surface shaped to concentrate incoming solar radiation onto a focal line, first and second rails, one rail attached to each edge of the reflector, and a set of truss connectors attached to the rails. The truss connectors and rails may form ways that enable constrained sliding engagement of the truss connectors along the rails before attachment of the truss connectors to the rails. The module may also include a plurality of framing members connected to the truss connectors and forming a structural lattice that cooperates with the reflector to lend rigidity to the solar collector module. At least some of the framing members may be disposed in front of the front reflective surface.
