The present invention is premised upon a system and method for an improved photovoltaic cladding device array with an interface member (500) for use on a building structure with other non-solar cladding materials (600). The interface member is disposed under a portion of the photovoltaic cladding elements (P) and includes a photovoltaic cladding element nesting portion and a building sheatin nesting portion.

1. A method of constructing a building-integrated photovoltaic device assembly on a surface of a structure, comprising the steps of: a. providing a plurality of photovoltaic (PV) sheathing elements, adapted to serve as an outer cladding of a structure, in one or more rows or columns as applied to the structure so that the plurality of photovoltaic sheathing elements when attached together form the building-integrated photovoltaic device assembly, which includes a bottom edge, and each of the PV sheathing elements including: i. a body portion including: 1. a lower surface portion that directly contacts the structure and2. an upper surface portion that receives one or more fasteners that attaches each of the PV sheathing elements to the structure;b. providing one or more interface members as applied to the structure, disposed under a portion of the bottom edge of the building-integrated photovoltaic device assembly, the one or more interface members including: 1. an photovoltaic device nesting portion,2. a building sheathing nesting portion, and3. one or more photovoltaic device retention features;c. placing and attaching the one or more interface members directly to the surface so that the one or more interface members form an interface row between the bottom edge of the building-integrated photovoltaic device assembly and a row of sheathing members;d. placing a first individual PV sheathing element of the plurality of PV sheathing elements in the first row of the PV sheathing elements on to the one or more interface members in the photovoltaic device nesting portion;e. attaching the first individual PV sheathing element to the one or more interface members with the one or more photovoltaic device retention features, and attaching the first individual PV sheathing element to the structure with one or more fasteners that extend through the upper surface portion;f. repeating steps c-e or d-e until the first row or the first column of PV sheathing elements are attached to the surface; andg. attaching a plurality of individual PV sheathing element in a second row and creating an overlap by placing the second row so that the second row covers a portion of each of the individual PV sheathing elements in the first row; andwherein the one or more retention features are a plurality of retention features that each have a generally “C” shaped hook structure. 2. The method according to claim 1, including the steps of providing the sheathing members, placing the sheathing member into the building sheathing nesting portion, and attaching the sheathing members to the structure. 3. The method according to claim 1, wherein the one or more interface members include an upper flashing portion that covers a portion of a building sheathing member and the upper flashing portion comprises a flexible ledge portion disposed forward of the photovoltaic device nesting portion and above the building sheathing nesting portion. 4. The method according to claim 1, wherein the one or more interface members comprise a flexible sheet that can be rolled out as applied to the structure. 5. The method according to claim 3, wherein the upper flashing portion comprises a removable flashing member. 6. The method according to claim 1, wherein the one or more interface members include an upper flashing portion and a lower flashing portion that are two discrete pieces, and the one or more photovoltaic device retention features are located on the upper flashing portion and the lower flashing portion and the retention features on the lower flashing portion are adapted to mate with the retention features of the upper flashing portion. 7. The method according to claim 1, wherein the interface members include one or more features that are a snow guard, an ice guard, or both. 8. The method according to claim 1, wherein the retention features comprise a mechanical fastening device, an adhesive, or both that connect the PV sheathing elements to the one or more interface members. 9. The method according to claim 6, wherein the retention features comprise a mechanical fastening device, an adhesive, or both that connect the PV sheathing elements to the one or more interface members. 10. The method according claim 3, wherein the upper flashing portion has a sufficient length to cover fasteners disposed on the sheathing member. 11. The method according to claim 1, wherein the one or more interface members include a second set of retention features that are located between each of the generally “C” shaped hook structures. 12. The method according to claim 1, wherein the one or more retention features are located at a forward edge of the one or more interface members so that the one or more retention features are located at the bottom edge of the building-integrated photovoltaic device assembly and assist in holding down a bottom edge of each of the PV sheathing elements against forces of wind up-lift. 13. The method according to claim 1, wherein the one or more photovoltaic retention features connect to the PV sheathing elements without creating additional holes in the structure. 14. The method according to claim 11, wherein the one or more retention features are located at a forward edge of the one or more interface members so that the one or more retention features are located at the bottom edge of the building-integrated photovoltaic device assembly and assist in holding down a bottom edge of each of the PV sheathing elements against forces of wind up-lift, and the one or more photovoltaic retention features connect to the PV sheathing elements without creating additional holes in the structure. 15. The method according to claim 1, wherein the one or more photovoltaic device retention features are an adhesive with a minimum peel force of about 5 pounds per linear inch measured using ASTM D 903-98 at a temperature between about −40° C. and about 85° C. 16. The method according to claim 1, wherein the one or more photovoltaic device retention features are an adhesive that has an elongation of about 500% or greater when measured using ASTM D 421-06, and the adhesive has a thickness after assembly from about 0.7 mm to about 2.0 mm.
