Base sheet integrated photovolatic roofing assemblies

摘要

Provided are novel building integrable photovoltaic (BIP) assemblies and methods of installation thereof on building structures. The BIP assembly includes a base sheet or a sheath, which may be a plywood board or an oriented strand (OSB) board, and multiple electrically interconnected photovoltaic inserts, which are attached to and supported by the base sheet. The base sheet is configured to be positioned directly the building structures, such as roof rafters. Various electrical components may be positioned within cavities of the base sheet and/or at the back side of that sheet. Such components are configured to align in between the roof rafters during installation. The spacing between the rafters provides access to the components and allows the components to extend away from the base sheet and into the spacing. Various electrical components may be installed and removed from the BIP assembly during its fabrication and/or installation.

主权项

1. A method of installing a building integrable photovoltaic (BIPV) assembly, comprising:
mechanically attaching a BIPV assembly directly to a rafter of a building structure, wherein the BIPV assembly comprises:
a plurality of electrically interconnected photovoltaic inserts, each photovoltaic insert comprising photovoltaic cell;a plurality of sets of electrical leads each extending from a different one of the plurality of electrically interconnected photovoltaic inserts; anda single base sheet comprising a front side supporting the plurality of electrically interconnected photovoltaic inserts and a back side, the base sheet comprising a plurality of through holes, each of the inserts being attached to the front side of the base sheet, wherein at least one of the sets of electrical leads of the plurality of photovoltaic inserts extends into at least one of the plurality of through holes such that the at least one set of electrical leads is electrically connected on the back side of the base sheet to at least one of a) an electrical component and b) another one of the sets of electrical leads of the plurality sets of electrical leads.
