Abstract:
A solar collector, which can be used for heating interiors, supplying hot water and heating process water, comprises: an enclosure (1) made of a composite polymer material, a transparent coating (2), and a heat exchanger (3) provided with channels for a heat-transfer agent. The transparent coating (2) and the heat exchanger (3) are combined with each other along the perimeter by a distance frame (4) to create a hermetically sealed heating package, and the air is released from the inner space (6) of the heating package to obtain vacuum, or the air is replaced by an inert gas therein. The heat exchanger (3) is designed as a metal plate and inside it or on its surface, there are arranged tubes having channels for circulating a heat-transfer agent, which are combined to create a single closed system having an inlet and an outlet on the surface of the solar collector, the heat exchanger surface facing the sun is applied with a dark coating, and the heating package is arranged in the enclosure (1) made of a composite polymer material.
Abstract:
A solar collector has an opaque cover (10) heated by solar energy. Heat flows from the opaque cover (10) by conduction, convection, and infrared emittance across a gap (52) within an at least substantially airtight enclosure (14) to an absorber (26) containing a working fluid. The exterior surface (22) of the opaque cover (10) has high solar energy absorptance and the interior surface (24) has high infrared emittance. The exterior surface (22) preferably has low infrared emittance. In one embodiment, fully wetted surface geometry (50, 52, 54) permits direct (44) and reflected (46) infrared absorption by the absorber (26). The opaque cover (10) eliminates the weight, cost and other shortcomings of glass. A hollow continuous side wall (60) with rounded corners (64) provides an embodiment that is robust yet economical, that is easy to manufacture and seal, that permits a reduced thickness of the opaque cover (10) and mitigates the destructive potential of severe winds, and that can withstand the compressive forces experienced by an evacuated solar collector.
Abstract:
A PV module including a PV device and a frame. The PV device has a PV laminate maintaining a plurality of PV cells at a front face. The PV cells are arranged in rows, including a first row adjacent an edge of the PV laminate. Adjacent ones of the PV cells of the first row are separated by a column spacing. The frame is assembled to the PV laminate, and includes a frame member having a ledge and a plurality of spaced fingers that are connected to, and spaced from, the ledge. The PV laminate is mounted between the ledge and the fingers, with one of the fingers being aligned with one of the column spacings. The PV module facilitates liquid drainage between the spaced fingers. Further, the fingers minimize shading effects presented by the frame member, thereby enhancing a GCR of the PV module.

A solar collector includes an enclosure having a bottom and side wall surfaces substantially made of plastic material and a transparent top surface. At least one panel unit is composed of elongated conduits interconnected at each end by a manifold and is movably affixed inside the enclosure and sized to freely expand and contract therein due to thermal changes. The enclosure has at least one controllable air vent mechanism responsive to expansion and contraction of the panel unit.
Abstract:
Described herein are solar energy apparatus that overcome many of the disadvantages and shortcomings of conventional solar energy absorption structures. The solar energy apparatus may comprise inexpensive material and have smaller dimensions to reduce the overall cost of the apparatus. The apparatus may also have coatings which help to maximize the amount of solar energy absorbed and minimize the deterioration of the apparatus due to overheating. The apparatus may include a system for monitoring and controlling the temperature of the apparatus to prevent overheating.

Date Dec. 8, 1983.A solar collector with a supporting panel made of fibrous material, the material being thicker on the bottom of the panel where greater insulation is required, and denser and thinner on the sides where greater strength is required. This design permits a thinner absorber panel to be used, resulting in decreased cost of materials and manufacture and enhanced performance and greater ease of construction.
