Mount and clamp assemblies
Mount and clamp assemblies employed in solar power installations are disclosed. In some embodiments, a mount assembly having a rail and opposing wings extending outwardly from the rail is disclosed. Each wing includes a top surface and a bottom surface for creating a chemical flashing, a groove and a sealant-receiving cavity extending away the bottom surface and upwardly into the wing, and a compressible seal with a circumferential pressure relief passageway. In some embodiments, a clamp having an upper member and a lower member with two horizontal flanges and a vertical flange is disclosed; in this embodiment, adjacent modules may be clamped together without an underlying structure mounted directly below to an installation surface. In another embodiment, a fourth flange is included in the mount assembly; in this embodiment, adjacent modules may be clamped together while being mounted directly to an installation surface.
1 . A mount assembly, comprising:
a rail and a pair of opposing wings, where
the rail includes:
a pair of first opposing sides, and
a pair of second opposing sides; and
each wing of the pair of opposing wings extends outwardly from one first opposing side, and
each wing of the pair of opposing wings includes:
a top surface and a bottom surface, and
at least one aperture fastener-receiving aperture;
wherein each wing of the pair of opposing wings further includes at least one fastener retainer extending above one aperture of the plurality of apertures, wherein each one of the at least one fastener retainer includes a plurality of fastener retainer flaps supported by a plurality of vertical guides extending between the plurality of fastener retainer flaps and the one aperture.
2 . The mount assembly of claim 1 , wherein the rail further includes a cross member extending between the pair of opposing wings.
3 . The mount assembly of claim 2 , wherein the cross member in slidable within the rail.
4 . The mount assembly of claim 3 , wherein the cross member includes an aperture.
5 . The mount assembly of claim 4 , wherein the aperture is threaded.
6 . The mount assembly of claim 1 , wherein
each wing of the pair of opposing wings further includes:
a groove extending away the bottom surface and upwardly into the wing,
a sealant-receiving cavity extending away the bottom surface and upwardly into the wing, and
a compressible seal with a circumferential pressure relief passageway, where
the compressible seal is disposed within the groove and extends downwardly beyond the bottom surface, and
at least one aperture extending upwardly from the sealant-receiving cavity to the top surface.
7 . The mount assembly of claim 1 , wherein
the plurality of fastener retainer flaps is configured to engage threads of a fastener when the fastener is inserted into the fastener retainer and positioned between the plurality of vertical guides, such that
the plurality of fastener retainer flaps facilitates a prepositioning of the fastener vertically and statically between the plurality of vertical guides prior to the mount assembly being positioned on the installation surface for mounting thereon.
8 . The mount assembly of claim 7 , further comprising:
a plurality of fasteners, where
the plurality of fasteners is configured to engage an installation surface when the mount assembly is mounted to the installation surface, such that
each fastener of the plurality of fasteners extends through one fastener retainer and one aperture.
9 . The mount assembly of claim 1 , further comprising:
a vertical interface configured to couple to the rail.
10 . The mount assembly of claim 9 , further comprising:
a clamp configured to couple to the vertical interface.
11 . The mount assembly of claim 10 , wherein the clamp is configured to clamp to at least one solar module.
