Abstract: The present disclosure relates generally to a roofing system including flashing, for example, suitable for protecting a roof from water leakage. The present disclosure relates more particularly to a roofing system including first, second, and third courses of shingles, where the second course overlaps the first and the third course overlaps the second. A flashing plate is disposed over the first course of shingles and partially under the second course of shingles. The flashing plate and the third course of shingles are spaced apart by a gap in a direction of the slope of the roof between a top edge of the flashing plate and a lower edge of the third course of shingles.

Abstract: Provided is a light-weight, easy to install, use and remove solar collector that may be manufactured inexpensively from readily available common materials, and which may be installed, removed, moved, and reinstalled almost anywhere by almost anyone without special tools or skills. In one embodiment, the solar collector comprises one or more collection tubes formed from attaching clear or substantially translucent material, such as clear vinyl, along the edges and over the top of dark colored or otherwise solar-energy-absorbant material, such as black polyethylene plastic, black vinyl-coated polyester, or any other suitable material, which may be insulated by an insulative layer. A dark-colored or otherwise solar-energy-absorbant air-permeable layer may also be located in the collection tube to increase heating of the air flowing through the collection tube. In addition to the solar collector is a fan, which may take the form of a forced-air window unit with thermostatic controls.

Abstract: The present disclosure relates to an energy supplying device intended to be used for energy collecting, energy transfer and energy release, but also for cooling and storing of energy, said energy supplying device (1) consists of at least three elongated profiles (3), which comprise a number of walls (2?, 2?) delimiting in the same elongated cavities (2), produced by extruding in a direction of extrusion (4) by aid of a tool, said cavities (2) provide space for a medium (5) such as gas or liquid to circulate or to be stored in said cavities (2) or a hose or a tube (9) located in these.

Abstract: A solar collector includes a first header, a second header and one or more riser tubes that connect the first header and second header. The solar collector is mounted to a surface, e.g., a roof, such that the headers are substantially parallel to a horizontal axis. The first header is curved so as to define a low point that facilitates drainage of liquid from the solar collector.

Abstract: A solar energy collecting system and method suitable for hot water generation using solar energy. The system includes multiport tubes between inlet and outlet manifolds. The tubes are formed of a metallic material, each tube has oppositely-disposed first and second flat surfaces between lateral edges thereof, longitudinally-opposed first and second ends, and multiple fluid channels between the first and second ends that are in fluidic parallel to each other. The inlet and outlet manifolds are coupled to the first and second ends of the tubes so that chambers within the inlet and outlet manifolds are fluidically connected to the fluid channels of the multiport tubes. During operation of the system, a fluid flowing through the fluid channels of the tubes is heated by direct solar radiation impinging the first flat surfaces of the tubes and optionally by reflected solar radiation impinging the second flat surfaces of the tubes.

Abstract: Solar panel for water-heater of the type comprising a heat exchanger made of moulded synthetic material, having a plurality of passages 7 in which a heat-exchanging fluid can circulate and a translucent cover sheet 17 attached to the exchanger with a clearance, characterized in that the heat exchanger constitutes the brace supporting the panel and consists of two identical half-shells 1a, 1b furnished with parallel longitudinal central projecting ribs 2a, 2b and one projecting edging rib 4a, 4b of greater dimension than a central rib, the two half-shells being bonded or heat sealed so that the central ribs define the abovementioned passages 7 and that the respective edging ribs 4a, 4b define a sealed hollow edging frame full of insulating air confined on the periphery of the exchanger.

Abstract: A coolant sealing structure for a solar cell of which the sealing property is maintained with high reliability in use for a long period. A solar cell has its light receiving surface and a reinforced portion formed around the fringe portion of the light receiving surface. The plate member is joined with the top of the reinforced portion by means of an anode joint process. A transparent member is joined with the plate member to form a coolant passage. This structure allows the solar cell to be directly cooled with the coolant flowing through the coolant passage. Since the solar cell is joined with the plate member, separation does not occur at the joined portion under repeated temperature changes. The coolant sealing structure can be used with high reliability for a long period.
