FIELD

[0001] The present teachings generally relate to an alignment features for forming a photovoltaic roofing system and a method of forming a photovoltaic roofing system using the alignment features.

BACKGROUND

[0002] Typically, photovoltaic arrays are placed in an elevated location such as a roof top of a home or a building or in a rack and frame that elevates the photovoltaic array so that the photovoltaic array is exposed to sunlight. The roofs on homes and/or buildings generally are formed by adding a plurality of pieces of panels together so that a generally contiguous surface is formed, which are supported by one or more trusses. Photovoltaic modules may be secured to the plurality of pieces of panels directly and/or indirectly via a connection structure such as a rack and frame. Each photovoltaic module of the photovoltaic array may include only an active portion and the active portions of two or more photovoltaic modules may be placed in close proximity with one another so that a photovoltaic array is formed over and/or on the connection structure. However, in cases where the photovoltaic modules provide roofing functions, the photovoltaic modules may include both an active portion and a support portion and the active portion of one photovoltaic module may fully and/or partially cover the support portion of an adjacent photovoltaic module to replace the framing and racking structure. The active portion and the support portion may be one integrally formed piece with the photovoltaic active portion located within the active portion so that in order to remove the photovoltaic active portion the entire photovoltaic module would be removed and replaced if necessary. In cases of building integrated photovoltaics, the support portion may provide roofing functions or structural functions for subsequent photovoltaic modules. The photovoltaic modules each have a portion that is directly connected to the roofing structure. Each photovoltaic module may also include a device that interconnects the photovoltaic modules together. This device may be added after the photovoltaic modules are connected to the roofing structure. This device may also be visible when the photovoltaic array is complete. The visibility of these devices may detract from the aesthetics of the photovoltaic array, these devices may become lost during installation, and these devices may increase installation time and expense.

[0003] Examples of some photovoltaic modules and photovoltaic arrays may be found in U.S. Patent Nos. 8,584,407 and 8,898,970 U.S. Patent Application Publication No. 2012/01 18349; and International Patent Application No. WO2013/019628 all of which are incorporated by reference herein for all purposes.

[0004] It would be attractive to have a system that conceals connection members so that the connection members connect two or more photovoltaic components together without the connection members being visible. It would be attractive to have an alignment feature that allows for blind installation of connection members. What is needed is a device that aligns two or more connection members together and indicates when the connection members are in a locked configuration. What is needed is an alignment feature that aligns two or more or even three or more photovoltaic components so that a connection can be made between the three or more photovoltaic components.

SUMMARY

[0005] The present teachings meet one or more of the present needs by providing: a photovoltaic array system comprising: (a) a plurality of photovoltaic components that are configured to be connected together; and (b) one or more alignment features located on at least two of the plurality of photovoltaic components; wherein the one or more alignment features are located in a side edge region of at least one of the plurality of photovoltaic components and in a top edge region of at least one of the plurality of photovoltaic components, and the one or more alignment features indicate when two or more of the plurality of photovoltaic components are aligned relative to each other so that the two or more photovoltaic components can be mated together to form a fixed connection.

[0006] The present teachings provide a method of a photovoltaic array comprising: placing one or more photovoltaic components in a first row or column; placing one or more photovoltaic components in a second row or column that at least partially overlaps the first row or column; aligning the one or more photovoltaic components in the second row or column with the one or more photovoltaic components in the first row or column using one or more alignment features; locking the one or more photovoltaic components in the second row or column to the one or more photovoltaic components in the first row or column by moving the one or more photovoltaic components in the second row or column relative to the one or more alignment features.

[0007] The teachings herein surprisingly solve one or more of these problems by providing a system that conceals connection members so that the connection members connect two or more photovoltaic components together without the connection members being visible. The present teachings provide an alignment feature that allows for blind installation of connection members.

DETAILED DESCRIPTION

[0032] The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the teachings, its principles, and its practical application. Those skilled in the art may adapt and apply the teachings in its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.

[0033] A plurality of photovoltaic components (e.g., active components and flashing components) of the teachings herein are combined together to form a photovoltaic array. The photovoltaic array collects sunlight and converts the sunlight to electricity. Generally, each of the active components (e.g., photovoltaic modules) may be individually placed in a structure that houses all of the photovoltaic modules forming all or a portion of a photovoltaic array. Preferably, each individual photovoltaic component may be connected directly to a structure (i.e., is a building integrated photovoltaic (BIPV)) and each of the individual photovoltaic components is electrically connected together so that a photovoltaic array is formed. The photovoltaic components may be connected to a support structure that forms a connection surface.

[0034] The connection surface may function to provide support to one or more photovoltaic components so that a photovoltaic array is formed. The connection surface may be a support structure such as a housing for containing one or more of the photovoltaic components. Preferably, the connection surface may be a roof. The roof may be made of any material that has sufficient strength to support the weight of the plurality of photovoltaic modules. The roof may be made of any material so that the plurality of photovoltaic modules may be directly connected to the roof. The plurality of photovoltaic components may be connected to the connection surface so that the photovoltaic components are adjacent to one another. For example, an edge of one photovoltaic components may be located substantially proximate to an edge of an adjoining photovoltaic components. Preferably, the photovoltaic components may partially overlap each other. For example, the active portion and/or a support portion of one photovoltaic module may overlap an overlap portion of one or more adjacent photovoltaic modules in a similar fashion to how roofing shingles are applied to a roof. Preferably, a support portion of a base plate of one photovoltaic module may extend at least partially over an overlap portion of an adjacent base plate.

[0035] The photovoltaic components may be aligned in rows (e.g., horizontally) or columns (e.g., vertically), but as discussed herein both rows and columns will be referred to as rows. The photovoltaic array may include two or more rows, three or more rows, four or more rows, or even five or more rows. Preferably, the photovoltaic array may include a plurality of rows. The combination of rows of photovoltaic components when connected together form a photovoltaic array that includes a peripheral edge. The peripheral edge is the outer edge that extends around an outer most region of the photovoltaic array. The photovoltaic components may be staggered from row to row. For example, an upper photovoltaic component may overlap a portion of two or more lower photovoltaic components. Preferably each photovoltaic component is staggered and overlaps two photovoltaic components and each of the overlapped photovoltaic components has a portion that extends outside of the overlapping photovoltaic component. Each of the photovoltaic components either overlaps one or more adjacent photovoltaic components, are overlapped by one or more adjacent photovoltaic components, or both overlap and is overlapped by one or more adjacent photovoltaic components. The overlap may form a double overlap so that each of the photovoltaic components is covered forming a shingle effect. The active components and the flashing components may connect together in an overlapped fashion forming the photovoltaic array as set forth herein.

[0036] Each of the photovoltaic components function to form a portion of the photovoltaic array that prevents the ingress of water. Each of the photovoltaic components functions to serve a roofing function. The photovoltaic components may each include a surface that removes water from the roofing structure, prevents water from penetrating into the photovoltaic array. Each photovoltaic component may be connectable to one or more adjacent photovoltaic components so that a water tight seal is formed. Each of the photovoltaic components include a peripheral edge. The peripheral edge is an edge that extends about a perimeter of each photovoltaic componentThe peripheral edge may overhang any connection members of the photovoltaic components. The peripheral edge may overhang the connection members so that connection members are not visible from the top. The peripheral edge may overhang the connection members so that during installation the installation is a "blind" installation. The connection members may be located in a central region of the photovoltaic components.

[0037] The connection members may function to connect two or more photovoltaic components together. The connections members may function to mate together and prevent fluid from passing through the photovoltaic array. The connection members may prevent wind uplift. The connection members may prevent lateral movement, longitudinal movement, vertical movement, or a combination thereof of two or more connected photovoltaic components. The connection members may be a male and female component. The connection members may form a mating relationship. The connection members may be a connection hook, a connection recess, or both. Each photovoltaic component includes at least one connection member. Each photovoltaic component may include a plurality of connection members. Some photovoltaic components may include only a connection hook or only a connection recess. Some photovoltaic components include both connection hooks and connection recesses. For example, a photovoltaic component may include a plurality of connection recesses in an overlap portion and a plurality of connection hooks in an active portion or a cap portion.

[0038] The one or more connection recesses may function to connect two or more adjacent photovoltaic components, two or more adjacent base plates, two or more photovoltaic modules, two or more flashing components, two or more active components, a flashing component and an active component, or a combination thereof together. The one or more connection recesses may prevent movement of two or more active components, two or more photovoltaic modules, two or more flashing components, or a combination thereof relative to each other. The one or more connection recesses may function to receive a portion of an adjacent photovoltaic component. The one or more connection recesses may extend along a width of the photovoltaic component. The one or more connection recesses may extend transverse to the slope of the roof. The one or more connection recesses may be located in the overlap portion, the support portion, the cap portion, or a combination thereof. The one or more connection recesses may be spaced apart along the photovoltaic component so that the connection recesses may receive a portion of two or more adjacent photovoltaic components (e.g., a connection hook). The one or more connection recesses may be located along edges but inside of the edge, in edge regions, in a central region, or a combination thereof of the photovoltaic components. Preferably the connection recesses are evenly spaced out across the base plate, the photovoltaic module, or both. The one or more connection recesses may be a plurality of connection recesses that each receives a portion of an adjacent photovoltaic component (e.g., each connection recess may receive a connection hook). The one or more connection recesses may be a through hole that extends through the photovoltaic component (e.g., flashing component or base plate). The one or more connection recesses may be visible from the top of the photovoltaic component. However, when another photovoltaic component extends over the connection recess the connection recess may be obscured from view. Thus, an installer may not be able to see the connection recess during installation. The connection recesses may be a recess in the photovoltaic component that does not extend through the photovoltaic component. The one or more connection recesses may be any shape that may receive a portion of an adjacent photovoltaic component so that the photovoltaic components are locked relative to each other, movement relative to each other is prevented, or both. The one or more connection recesses may include one or more walls that create a border around the connection recesses.

[0039] The one or more walls may function to support an adjacent photovoltaic module above the connection recess. The one or more walls may function to prevent fluid from entering into the connection recess. The one or more walls may be an elevated surface that extends from the base plate proximate to the connection recesses. The walls may extend sufficiently high so that the walls contact a bottom side of an adjacent photovoltaic component and the bottom side acts as a lid. The walls may be one unitary structure that extends from the photovoltaic component (e.g., vertically away from a top surface of the photovoltaic component). The walls may assist in creating a fixed connection with an adjacent photovoltaic module. The walls may assist in placing two adjacent photovoltaic components in tension.

[0040] The one or more connection hooks may function to prevent movement (e.g., vertical, horizontal, longitudinal, diagonal, or a combination thereof) of two or more photovoltaic components, two or more photovoltaic modules, two or more active components, two or more flashing components, at least one flashing component and at least one active component, or a combination thereof relative to each other. The connection hooks may mate with the connection recesses to function to prevent movement of two or more photovoltaic components relative to each other. The one or more connection hooks may prevent wind uplift. The one or more connection hooks may extend into a connection recess. The one or more connection hooks may be complementary to the one or more connection recesses. The one or more connection hooks may extend through a connection recess. The one or more connection hooks may contact a portion of the connection recess, an area adjacent to the connection recess, a rear side of the photovoltaic components, the photovoltaic module, a rib, or a combination thereof. The one or more connection hooks may extend through the connection recess and then turn and contact a portion of the photovoltaic components, an opposing side, an internal wall, or a combination thereof. The one or more connection hooks may extend into the connection recess and contact a portion of the inside of the connection recess. The one or more connection hooks may be smaller than the connection recess. A gap may be located on one or both sides, one or both edges, or both of the connection hooks. The one or more gaps may allow the connection hooks to extend into the connection recess without being completely aligned (e.g., during blind installation). The gaps may be sufficiently large so that the connection hooks can move side to side in the connection recess during formation of a connection. The one or more connection hooks may extend into the connection recess and into contact with a rib or wall that puts tension of the connection hook so that the photovoltaic component is prevented from lifting. The one or more connection hooks may be located along edges but inside of the edge, in edge regions, in a central region, or a combination thereof of the base plate. Preferably the connection hooks are substantially evenly spaced out across the photovoltaic components. The photovoltaic components may include two or more, three or more, four or more, or even five or more connection hooks.

[0041] The one or more connection hooks may have a portion that extends in the direction of the slope of the connection structure, opposite the slope or the connection structure, perpendicular to the direction of the slope of the connection structure, or a combination thereof. The one or more connection hooks may extend from a rear side of the photovoltaic components. The one or more connection hooks may be substantially obscured from view when the photovoltaic component is viewed from the top or a top perspective view due to the connection hooks being located inside of a peripheral edge, in a central region, or both. The one or more connection hooks may include one or more lock features. The one or more lock features may form a fixed connection with a connection recess, a rib, a wall, or a combination thereof. The one or more lock features may function to provide an indication that a lock is formed. The one or more lock features may function to provide resistance when detaching the connection hook from the connection recess. The one or more connection hooks may be on an opposite side of the base plate as the handles, on an opposite end of the overlap portion as the handles, or both. The one or more connection members may be located proximate to one or more fastener supports.

[0042] The fastener supports may be located within the active portion, the overlap portion, the support portion, cap portion, in the photovoltaic components, or a combination thereof. Preferably, the fastener supports may be located within the overlap portion. The fastener supports may be a through hole that extends through the overlap portion, a weakened area so that a fastener may be placed through the fastener support, a removable portion, a punch out, an area of lower hardness, or a combination thereof. The one or more fastener supports and preferably a plurality of fastener supports may be located in the support portion, the overlap portion, or both of the base plate, the flashing components, the active components, or a combination thereof. The one or more fastener supports may accept one or more fasteners.

[0043] The plurality of photovoltaic components may be connected to the connection surface by any fastener that has sufficient strength to withstand environmental conditions and form a secure connection. The plurality of photovoltaic components may be connected to a connection surface with a mechanical fastener, an adhesive, an interlocking connection with an adjacent photovoltaic module, or a combination thereof. The fasteners may be a screw, nail, bolt, staple, rivet, or a combination thereof. The adhesive may be any adhesive with sufficient strength to connect the photovoltaic components to the connection surface. The adhesive may be epoxy based, silicone based, acrylic based, a urethane based, a polyamide based, a one part adhesive, a multi-part adhesive, a natural adhesive, a synthetic adhesive, a butyl rubber, polyolefin based adhesive, or a mixture thereof. The fastener may be a combination of a mechanical fastener and an adhesive fastener. The connection may be a permanent connection, a removable connection, or both so that photovoltaic components are connected to a connection surface. The photovoltaic components may be lightweight and have a low profile so that the photovoltaic components may be connected directly to the connection surface by the fasteners as are discussed herein. The one or more fastener supports and fasteners may be located outside of the connector channels so that connectors may extend into and be removed from the connector channels.

[0044] The one or more connector channels may function to receive the one or more connectors of the pv laminate, one or more row to row connectors, one or more photovoltaic component to photovoltaic component connectors, or a combination thereof (hereinafter all referred to as connectors). The one or more connector channels may function to protect the pv laminate connectors from contact, a lateral force, a longitudinal force, an impact, or a combination thereof. The one or more connector channels may assist in forming a connection between a connector (e.g., that connects two adjacent photovoltaic modules) and connector of a pv laminate. The one or more connector channels may assist in forming a connection between a row to row connector (i.e., a connector in a row to row flashing piece) and a photovoltaic laminate. The one or more connector channels may assist in electrically connecting two adjacent pv laminate connectors, two adjacent photovoltaic components, a photovoltaic component to an inverter, or a combination thereof. The one or more connector channels may be a recess that receives the connector of the pv laminate. The one or more connector channels may be located on opposite edges, in opposing edge regions, on opposite sides, or a combination thereof of the base plate of a photovoltaic module.

[0045] The one or more base plates may function to support a photovoltaic laminate. The one or more base plates may function to protect a roofing structure from fluids. Each base plate may include a support portion, an active portion, and an overlap portion. The active portion may overlap all or a portion of one or more adjacent photovoltaic components, one or more flashing components, or both (e.g., the overlap portion) forming a "double overlap" so that each photovoltaic module may be protected and connected to a connection surface and/or so that the combined photovoltaic components may form a shingle structure for diverting fluids from the roof of the structure. Each of the photovoltaic modules may have a portion that may be indirectly and/or directly connected to a connection surface. The base plate may directly connect to a connection surface and the photovoltaic laminate may be connected to a support portion of the base plate (i.e., the photovoltaic laminate may be indirectly connected to the connection surface). Preferably, the overlap portion of each of the photovoltaic modules may be directly connected to a connection surface, and the active portion may be connected directly to the overlap portion or directly to the connection surface by a fastener that extends through the overlap portion, around the overlap portion, through a fastener support in the overlap portion, or a combination thereof. More preferably, each of the photovoltaic modules may include a base plate and a photovoltaic laminate and the base plate is connected to a connection surface by one or more fasteners that extend through fastener supports and preferably a plurality of fasteners that extend through fastener supports.

[0046] The base plate may be connected to the support structure and function to provide roofing functions. The base plate may function to connect a photovoltaic laminate (hereinafter pv laminate) to a connection surface (e.g., a roof). The base plate may function to allow for decoupled expansion and contraction of the pv laminate relative to the base plate or vice versa. The base plate may function to allow for removal, replacement, repair, or a combination thereof of the pv laminate without removal of the entire pv module from the connection surface. The base plate may connect the pv laminate to a connection surface. The base plate may protect one or more connectors and or wiring. The base plate may retain roofing functions, fire retardant properties, or both when the pv laminate is removed from the base plate.

The handles may be located in an overlap portion.

[0048] The overlap portion may function to receive a portion of one or more photovoltaic components. The overlap portion may function to provide support to one or more photovoltaic components.

Preferably, the support portion may support one or more pv laminates during transportation, installation, or both. The support portion may function to support the pv laminate when a load is applied to the pv laminate when the pv laminate is connected to a connection surface. For example, when the photovoltaic module is connected to a roof and a person walks across the photovoltaic array the support portion may resist bending of the pv laminate so that the pv laminate is not damaged. The support portion may function to provide support for one or more adjacent photovoltaic modules. The support portion of a first photovoltaic component may function to overlap one or more connectors of one or more second adjacent photovoltaic modules so that the one or more connectors of the one or more second adjacent photovoltaic modules are protected.

The active portion may be any portion of the photovoltaic module that produces electricity when the active portion is in contact with sunlight. The pv laminate may be made of any material so that when sunlight is directed on the active portion the sunlight is converted into electricity. The pv laminate may be made of one or more photovoltaic cells having a photoactive portion. Preferably, the pv laminate may be made of a plurality of photovoltaic cells. The photovoltaic cells may be made of any material that assists in converting sunlight into electricity. The photovoltaic cells may be of any type and material known in the art. Some non-limiting examples of materials that the photovoltaic cells may be made of include crystalline silicon, amorphous silicon, cadmium telluride (CdTe), gallium arsenide (GaAs), copper chalcogenide type cells (e.g. copper gallium selenides, copper indium gallium selenides (CIGS), copper indium selenides, copper indium gallium sulfides, copper indium sulfides (CIS), copper indium gallium selenide sulfides, etc. (i.e., known generally as CIGSS)) , thin-film lll-V cells, thin-film ll-VI cells, IB-IIIA- chalcogenide (e.g., IB-IIIA-selenides, IB-IIIA-sulfides, or IB-IIIA-selenide sulfides), organic photovoltaics, nanoparticle photovoltaics, dye sensitized photovoltaic cells, and/or combinations of the described materials. In one specific example, the copper indium gallium selenides may be represented by the formula Culn(1-x)GaxSe(2-y)Sy where x is 0 to 1 and y is 0 to 2. For copper chalcogenide type cells, additional electroactive layers such as one or more of emitter (buffer) layers, conductive layers (e.g. transparent conductive layers) or the like maybe used in CIGSS based photovoltaic cells are contemplated by the teachings herein. The active portion may be flexible or rigid and come in a variety of shapes and sizes, but generally are fragile and subject to environmental degradation. In a preferred embodiment, the active portion is a cell that can bend without substantial cracking and/or without significant loss of functionality. Other materials and/or combinations are contemplated herein especially those compositions disclosed in paragraph 0054 of U.S. Patent Application Publication No. 2012/0118349, which is incorporated herein by reference as to materials for the active portion. The photovoltaic cells of the photovoltaic laminate may be arranged in parallel, series, mixed series-parallel, and/or may be provided in independent circuits. The photovoltaic laminate may be a combination of layers and may form an assembly.

[0055] The pv laminate assembly may include one or more of the following components: a forward protective layer, a rearward protective layer, a reinforcement, a photovoltaic cell, a peripheral moisture sensitive edge seal, one or more internal protecting layers, dielectric materials as may be needed to manage the penetration of electrical components outside the laminate, attached connectors and wiring boxes, connector support structures including junction boxes, integrated low profile connectors, encapsulants, moisture resistant back sheets that may optionally include metallized sub layers, or a combination thereof. One example of a pv laminate may include a top layer of glass or a polymeric moisture barrier, an encapsulant layer, an electrical assembly comprising cells, bypass diodes and busses, a rear encapsulant layer, an aluminum based multi-layer back sheet, another encapsulant layer, a rearward protective layer, additional layers around the connector area including a connector support structure, an encapsulant, a dielectric layer, a connector sealant material such as an adhesive with a moisture barrier or another adhesive sealant or potting material, the low profile connector attached to the cells with bus terminals, another layer of encapsulant, and another dielectric layer. The rearward protective layer may help protect the laminate from any protrusions or abrasion from the support structure of the base plate.

For example, if a first lower photovoltaic component (e.g., photovoltaic module) includes four connection recesses and a second lower photovoltaic component includes two connection recesses (e.g., a right piece), the one or more horizontal alignment features may align a third top photovoltaic component so that the third top photovoltaic component partially overlaps both the first and second lower photovoltaic components so that two connection hooks extend into each of the lower photovoltaic components forming a connection. The horizontal alignment features may assist in creating a proper overlap, proper offset, or both between photovoltaic components. The horizontal alignment features may be a vertical line, a vertical marking, or both. The horizontal alignment feature may indicate where a side edge is located relative to the photovoltaic component. The horizontal alignment feature may be located in a central region of the photovoltaic component. The horizontal alignment feature may bisect a photovoltaic component along its height so that two equally sized pieces are formed on each side of the horizontal alignment feature. The horizontal alignment feature may be located on a bottom piece, a bottom right plus piece, a bottom left plus piece, a photovoltaic module, or a combination thereof. The horizontal alignment feature may contact one or more vertical alignment features, may be located proximate to one or more vertical alignment features, or both.

[0089] The one or more vertical alignment features may function to vertically align two or more connection members. The one or more vertical alignment features may function to vertically align two connection members relative to each other during a blind connection. The one or more vertical alignment features may function to indicate an unlocked position, a locked position, or both. The one or more vertical alignment features of a first photovoltaic component may align with vertical alignment features of a second photovoltaic component. The one or more vertical alignment features of a first photovoltaic component may be moved between two vertical alignment features of a second photovoltaic component and as the vertical alignment feature is moved between the first vertical alignment feature and the second vertical alignment feature or vice versa the connection members may be located together or unlocked. The vertical alignment feature may be aligned with one or more common features of an adjacent photovoltaic component. For example, the vertical alignment feature may be aligned with a top edge, a bottom edge, or both of an adjacent photovoltaic component. The vertical alignment feature may be located in a central region, an edge region, along a side, along an edge, extend from a top surface to an edge, or a combination thereof. Preferably, the vertical alignment features are located on a top surface in either a central region or one or both edge regions. The vertical alignment features may be horizontal features (e.g., extend in the transverse direction relative to the slope of the roof. The vertical alignment features may extend the full width of the photovoltaic component. The vertical alignment features may extend a portion of the width (e.g., 20 percent or less, 10 percent or less, or even 5 percent or less of the total width) of the photovoltaic component. The vertical alignment features may be free of additional markings or indications. The vertical alignment features may be located on a top right plus piece, a top right minus piece, a bottom piece, a bottom right plus piece, a bottom left plus piece, a left piece, a top piece, a top left minus piece, a top left plus piece, a step in right piece, a step in left piece, a right piece, a photovoltaic module, or a combination thereof. The one or more alignment features may include a cut indicator.

[0090] The one or more cut indicators may function to indicate a location of a cut of a photovoltaic component. The one or more cut indicators may indicate a location of alignment for one or more adjacent photovoltaic components. The one or more cut indicators may be a vertical alignment feature, a horizontal alignment feature, or both. The one or more cut indicators may be located in the edge regions. The one or more cut indicators may run a length, a width, or both of the photovoltaic component. The one or more cut indicators may be located only in flashing components. The one or more cut indicators may align with one or more adjacent alignment features, one or more edges, or both. The one or more cut indicators may align a row to row component. The one or more cut indicators may be removed when a photovoltaic component is cut so that the edge of the photovoltaic component abuts an adjacent photovoltaic component.

[0091] A photovoltaic array may be formed by a method. The method may perform one or more of the following steps in virtually any order. The photovoltaic array may be entirely completed before any standard roofing components (e.g., roof shingles) are added to the roof. The photovoltaic array may be added after a majority of the standard roofing components are added to the roof. Preferably, at least some of the flashing components are added to the roof and then the roofing components are added around the flashing components, photovoltaic components, or both. Creating a starter row. Aligning the photovoltaic components in the starter row relative to each other. Connecting the starter row to a support structure. Creating a row that at least partially covers the starter row. Aligning a photovoltaic component over one or more and preferably two or more components of the starter row. Aligning one or both edges of the overlapping photovoltaic component with a horizontal alignment feature. Aligning a vertical alignment feature with a vertical alignment feature of one or both of the photovoltaic components in the starter row. Connecting the overlapping photovoltaic component with the one or more photovoltaic components of the starter row. Extending a connection hook into a connection recess with only using the alignment features. Moving the overlapping photovoltaic component so that a second alignment, a top edge, or some other feature aligns with the vertical alignment feature. Locking the overlapping photovoltaic component in place by vertically moving the overlapping photovoltaic component relative to the starter row. Fastening the overlapping photovoltaic component to the support structure. Continuing to align photovoltaic components along the starter row until a complete row is formed. Forming another row (e.g., third row) above the row overlapping (e.g., second row) the starter row (e.g., the first row). Repeating until a photovoltaic array of a sufficient size and shape is created. Placing a final row over the second to last row of photovoltaic components. Capping the photovoltaic components with a final row so that a water tight structure is created. A final row component may be horizontally aligned, vertically aligned, or both over the top row of photovoltaic components. The connection may be formed while the connection members are concealed from view. A blind connection may be formed between two or more connection members.

During formation of a connection, the vertical alignment features 204 on the active component 20 and the flashing component 60 are aligned so that the connection hook (not shown) aligns with the connection recess 14. Once the connection hook is located within the connection recess, the flashing component is moved so that the vertical alignment feature 204 moves from being aligned with the vertical alignment feature 204 of the active component to a top edge 30 of the active component so that the connection hook is in communication with the connection recess.

For values which are less than one, one unit is considered to be 0.0001 , 0.001 , 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner.

[00117] Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of "about" or "approximately" in connection with a range applies to both ends of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30", inclusive of at least the specified endpoints.

[00118] The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The term "consisting essentially of" to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination. The use of the terms "comprising" or "including" to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments that consist essentially of the elements, ingredients, components or steps. By use of the term "may" herein, it is intended that any described attributes that "may" be included are optional.

[00119] Plural elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step might be divided into separate plural elements, ingredients, components or steps. The disclosure of "a" or "one" to describe an element, ingredient, component or step is not intended to foreclose additional elements, ingredients, components or steps.

[00120] It is understood that the above description is intended to be illustrative and not restrictive. Many embodiments as well as many applications besides the examples provided will be apparent to those of skill in the art upon reading the above description. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The omission in the following claims of any aspect of subject matter that is disclosed herein is not a disclaimer of such subject matter, nor should it be regarded that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter.
