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 module for installation on a structure includes a laminate for converting solar energy into electricity. The solar module also includes a mount releasably connected to the laminate for mounting the solar module on a surface of the structure. The mount includes openings to receive fasteners for securing the mount to the surface of the structure. The solar module has a pre-mount configuration in which the mount is connected to the laminate as a single unit. The mount is sized to allow the solar module to be shipped in the pre-mount configuration.

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 heat exchange device including a flexible hinge, a solar collector, a tank containing serpentine or coiled tubes which contain municipal water, wherein the tank contains thermal transmission vents designed for outflow of hot gasses from an attic, an insect screen, a precipitation drain and an attachment area is hereby disclosed.

A solar panel mounting system forming an opening for holding solar panels therein for easy installation and removal and replacement. The system includes a plurality of support members adapted for positioning on a support surface. A roof panel is positioned on a top surface of adjacent support members and compressibly held in place by an astragal which is fastened to the support member sandwiching the roof panel between the astragal and the support member. A solar panel opening is formed between projecting portions on opposing sides of the roof panel which extend at an angle substantially perpendicular to a top surface of the support member.

A solar energy collector arrangement that includes a plurality of solar collectors arranged in at least two rows and at least two columns, and at least one fastening member. A fastening member in the middle of solar energy collector arrangement is configured to couple to four solar energy collectors around it, and fastening members in an edge area of the solar energy collector arrangement are configured to couple and align two solar energy collectors to each other.

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

Photovoltaic thermal (PVT) apparatus 10 combines a photovoltaic panel (PV) panel 24 and solar air heater (SAH). The SAH includes body 12 with hollow interior 14 defining ducts 16a, 18a for air inlet 16 and air return 18. Jets 22 provide air to convey heat from the PV panel underside. Spaces between the jets provide drains 26 for warmed air to flow away. Flow modifiers/deflectors 124 can guide the airflow. A fan 42 pushes ambient air into the inlet 16 via air handling unit (AHU) 50. Return warm air flows via the AHU to escape via the ambient exhaust 40. A combined thermal transfer and storage unit 52 determines whether air from the PVT panel(s) diverts to the interior space. For cooler ambient conditions, the PVT apparatus can radiate heat to return cooled air into the space. The PVT apparatus can harvest condensation, heat/cool pools and industrial processes.

Watertight anchoring (2) for securely fastening elements (3, 4) to a building (1), comprising abase or support {6) anchored in a supporting structure (7) of the building (1); a heat-insulating layer (17}; a first watertight layer (25) applied over the heat-insulating layer (17} and the base or support (6); a bearing structure (28) fixed to the base or support (6) and a second watertight layer (38) applied over parts of the aforementioned bearing profiles (29) and over parts (39) of the first watertight layer (25) that, are adjacent to the respective bearing profiles (29).

An attachment system for roof-mounted equipment of this disclosure includes a pedestal having rails and corresponding channels at a top and bottom wall surface, the rails and channels located below the bottom wall surface configured to receive an adhesive for mounting the pedestal to a roof structure without penetrating the roof, the rails and channels located below the top wall surface including at least one channel configured to accept a fastener of the piece of equipment to be mounted on the pedestal.
