摘要:
Provided are novel building integrable photovoltaic (BIP) modules having specially configured attachment structures for securing these modules to building structures and other BIP modules. In certain embodiments, a BIP module includes a base sheet supporting photovoltaic cells and having a rigid polymer portion and a flexible polymer portion. The flexible portion is designed to be penetrated with mechanical fasteners during installation. The flexible portion may include fastening pointers and/or through holes for identifying specific penetration locations. The rigid portion provides necessary structural rigidity and support to the module and more specifically to the photovoltaic cells. In certain other embodiments, a BIP module includes an adhesive bumper strip disposed along one edge of the module and configured for secure this module with respect to another module. During installation, the strip is positioned between a back sealing sheet of one module and a front sealing sheet of another module.

Provided are novel building integrable interconnection structures having field-configurable shapes and methods of installing thereof. An interconnection structure may be cut or otherwise modified in the field during installation to form one or more openings. These openings can then be positioned around various obstacles that are frequently present in building installation areas. Some examples of such obstacles include chimneys, vents, and skylights. In some embodiments, the interconnection structures can be provided as part of a set or configured to be installed in an array with building integrable photovoltaic (BIPV) modules of the same size. This installation configuration allows preserving an offset between adjacent rows of the array. Furthermore, the interconnection structures can have the same perimeter features as the BIPV modules, such as electrical connectors and moisture flaps. These features provide electrical continuity and sealing characteristics in an array of BIPV modules despite the presence of obstacles on building structures.

Provided are novel Building Integrable Photovoltaic (BIPV) modules having one or more connectors that are movable between extended and retracted positions. Connector adjustment may be performed in the field, for example, during installation of a module. In certain embodiments, a connector includes a connector body and extension body. The extension body flexibly attaches the connector body to the module and allows the connector body to move with respect to the module edge. In an extended position, the connector body is positioned closer to the edge and is configured to make electrical connections to a joiner connector for interconnecting with an adjacent module. In a retracted positioned, the connector body is positioned further from the edge and is configured to make electrical connections to a jumper for interconnecting the conductive elements of the connector. In certain embodiments, a jumper does not protrude beyond the edge when connected to the connector body.

Embodiments provide a wire retaining apparatus including a base and a plurality of retention members. The base has a first end and a second end opposite the first end, and an upper side and a lower side. The plurality of retention members extend away from the upper side of the base. Each retention member includes a wall portion and a flange portion that protrudes from an upper peripheral portion of the wall portion. The flange portion is angled upwardly away from the upper side of the base forming a retention gap to receive one or more wires of different diameter.

Provided are novel building integrable photovoltaic (BIP) modules and methods of fabricating thereof. A module may be fabricated from an insert having one or more photovoltaic cells by electrically interconnecting and mechanically integrating one or more connectors with the insert. Each connector may have one or more conductive elements, such as metal sockets and/or pins. At least two of all conductive elements are electrically connected to the photovoltaic cells using, for example, bus bars. These and other electrical components are electrically insulated using a temperature resistant material having a Relative Temperature Index (RTI) of at least about 115° C. The insulation may be provided before or during module fabrication by, for example, providing a prefabricated insulating housing and/or injection molding the temperature resistant material. The temperature resistant material and/or other materials may be used for mechanical integration of the one or more connectors with the insert.

Provided are novel interconnecting strips for electrically connecting building integrable photovoltaic (BIPV) modules in a photovoltaic array. An interconnecting strip can be provided between a building structure and the BIPV modules, with electrical connections established by lowering the modules onto the strip previously positioned on the structure. The strip can includes two or more terminal groups aligned with different rows of BIPV modules. Each terminal group includes two or more connector terminals for connecting to the modules in that row. The interconnecting strip also includes leads extending between terminal groups and connecting connector terminals of different groups. In certain embodiments, terminal groups are offset with respect to adjacent groups to align with BIPV modules that are similarly offset to provide a moisture barrier. The interconnecting strip may be reconfigured in the field to provide different electrical connection schemes among BIPV modules.
摘要:
Building integrable photovoltaic (BIP) modules include photovoltaic inserts for producing electrical power and supporting structures for mechanically attaching and supporting the insert with respect to a building structure, such as roof tops. The supporting structures may include ventilation ribs that form ventilation channels under the photovoltaic insert and, in certain embodiments, under other components of the module. These ribs may be used to provide mechanical support to the entire module. In specific embodiments, ventilation channels of one module are configured to coincide with ventilation channels of one or more other like modules and to form a continuous channel along the roof edge. The supporting structures may be used to form moisture barriers in between two modules, such as side glitters. In certain embodiments, supporting structures are separate components and are attached to the insert to form a module during fabrication or installation of the module on a building structure.
