A tile system comprises at least two tiles and at least one elongate support. Each tile is generally rectangular in shape and has a first edge, and a second edge, the second edge being generally opposite the first edge. Each elongate support has an attachment portion and a support portion. Proximate the first edge each tile is provided with a groove, the groove being configured to receive the support portion of one of the elongate supports and a portion of an adjacent tile proximate its second edge.

A roof mounting system for the attachment of an article to a roof, the system comprising a plurality of PV modules each having at least one corner and a frame member, a flashing member having a top surface; an upstanding sleeve attached to the top surface of the flashing member; an elevated water seal having a borehole formed therethrough, the elevated water seal further comprising at least one screw for providing a waterproof seal between the article and the roof structure; and whereby the plurality of PV modules are interlocked in a way to provide a corner-to-corner coupling arrangement supported above the roof through the frame members of the plurality of PV modules.

A mounting assembly includes a rail configured to support a photovoltaic module. The rail includes a first slot, a second slot, and a web extending between the first slot and the second slot. The web being offset from a plane extending along an outer surface of the rail, so as to form a recess in the second side of the rail. The mount assembly further includes a clip configured to be secured to the rail and to a secondary structure. The clip includes a base having a flange extending from an end of the base, and an arm extending from the base in a second direction opposite the first direction, the flange being inserted in the second slot when the clip is secured to the rail and the secondary structure and at least a portion of the arm abuts the recess of the rail when the clip is secured to the rail.

A roof mounting system for the attachment of an article to a roof, the system comprising a plurality of PV modules each having at least one corner and a frame member, a flashing member having a top surface; an upstanding sleeve attached to the top surface of the flashing member; an elevated water seal having a borehole formed therethrough, the elevated water seal further comprising at least one screw for providing a waterproof seal between the article and the roof structure; and whereby the plurality of PV modules are interlocked in a way to provide a corner-to-corner coupling arrangement supported above the roof through the frame members of the plurality of PV modules.

In an embodiment, a solar energy system includes multiple photovoltaic modules, each oriented substantially at a same angle relative to horizontal. The angle is independent of a latitude of an installation site of the solar energy system and is greater than or equal to 15 degrees. The solar energy system defines a continuous area within a perimeter of the solar energy system. The solar energy system is configured to capture at the photovoltaic modules substantially all light incoming towards the continuous area over an entire season.

A roof mounting system for the attachment of an article to a roof, the system comprising a plurality of PV modules each having at least one corner and a frame member, a flashing member having a top surface; an upstanding sleeve attached to the top surface of the flashing member; an elevated water seal having a borehole formed therethrough, the elevated water seal further comprising at least one screw for providing a waterproof seal between the article and the roof structure; and whereby the plurality of PV modules are interlocked in a way to provide a corner-to-corner coupling arrangement supported above the roof through the frame members of the plurality of PV modules.

A system for mounting solar panels on a building may include panel mounting brackets each including a base to be positioned on the building and a vertical extension having a proximal end coupled to the base and a distal end vertically spaced apart from the base. The system may also include interior mounting clamps each including a leg having a proximal end to be coupled to the distal end of the vertical extension of a given panel mounting bracket and a distal end. Each interior mounting clamp may also include a first lateral arm for securing a first solar panel to the given panel mounting bracket, and a second lateral arm for securing a second solar panel to the given panel mounting bracket. The second lateral arm may have a bottom surface positioned vertically above a bottom surface of the first lateral arm along the leg.

A roof mounting system for the attachment of an article to a roof, the system comprising a plurality of PV modules each having at least one corner and a frame member, a flashing member having a top surface; an upstanding sleeve attached to the top surface of the flashing member; an elevated water seal having a borehole formed therethrough, the elevated water seal further comprising at least one screw for providing a waterproof seal between the article and the roof structure; and whereby the plurality of PV modules are interlocked in a way to provide a corner-to-corner coupling arrangement supported above the roof through the frame members of the plurality of PV modules.
