Photovoltaic module mounting system
A solar array mounting system having unique installation, load distribution, and grounding features, and which is adaptable for mounting solar panels having no external frame. The solar array mounting system includes flexible, pedestal-style feet and structural links connected in a grid formation on the mounting surface. The photovoltaic modules are secured in place via the use of attachment clamps that grip the edge of the typically glass substrate. The panel mounting clamps are then held in place by tilt brackets and/or mid-link brackets that provide fixation for the clamps and align the solar panels at a tilt to the horizontal mounting surface. The tilt brackets are held in place atop the flexible feet and connected link members thus creating a complete mounting structure.
1. A photovoltaic module mounting system comprising:
a plurality of feet, each foot formed at least partially from a flexible material, wherein each foot comprises:
a rubber body having two perpendicular slots on a top surface; and
at least one metal cruciform attached to the rubber body;
a tilt bracket attached to each foot;
a plurality of metal first links connecting the feet together in an axis of a first direction;
a plurality of metal second links connecting the feet together in an axis of a second direction;
wherein the feet, first links and second links form an integrated grid for mounting photovoltaic modules.
2. The mounting system of claim 1 , wherein the foot comprises two metal cruciforms, wherein one cruciform is attached to a bottom surface of the rubber body, and a second cruciform is attached on the a top of the body in the two perpendicular slots.
3. The mounting system of claim 2 , wherein each foot further comprises a plurality of threaded rods to connect the first and second links to the foot.
4. The mounting system of claim 3 , wherein the tilt bracket is bolted to the foot on top of the second cruciform.
5. A photovoltaic mounting system comprising:
a plurality of feet, each foot comprising:
a rubber body having two perpendicular slots on a top surface; and
two metal cruciforms, wherein one cruciform is attached to a bottom surface of the rubber body, and a second cruciform is attached on top of the rubber body in the two perpendicular slots;
a tilt bracket attached to each foot, wherein the tilt bracket comprises:
an upper mounting opening;
a lower mounting opening;
an angled front edge, located between the upper and lower mounting openings; and
four extensions which align with the respective slots of a respective foot, each extension having a lip to engage a link;
a plurality of metal first links connecting the feet together in a first direction;
a plurality of metal second links connecting the feet together in a second direction; and
wherein the feet, first links and second links form an integrated grid for mounting photovoltaic modules.
6. The mounting system of claim 5 , further comprising:
at least one mid-link bracket connected to a first link between the feet, the mid-link bracket comprising:
an upper mounting opening;
a lower mounting opening;
an angled front edge, located between the upper and lower mounting openings; and
a mounting channel having a lip on each end to engage a link.
7. The mounting system of claim 5 , further comprising at least one center panel support connected to each first link between feet.
8. The mounting system of claim 5 , further comprising a foot arranged under each mid-link bracket.
9. A photovoltaic system comprising:
a photovoltaic mounting system comprising:
a plurality of feet, each foot comprising:
a rubber body having two perpendicular slots on a top surface; and
two metal cruciforms, wherein one cruciform is attached to a bottom surface of the rubber body, and a second cruciform is attached on top of the rubber body in the two perpendicular slots;
a tilt bracket attached to each foot, wherein the tilt bracket comprises:
an upper mounting opening;
a lower mounting opening;
an angled front edge, located between the upper and lower mounting openings; and
four extensions which align with the respective slots of a respective foot, each extension having a lip to engage a link;
a plurality of metal first links connecting the feet together in a first axis direction;
a plurality of metal second links connecting the feet together in a second axis direction;
at least one mid-link bracket connected between the feet, the mid-link bracket comprising:
an upper mounting opening;
a lower mounting opening;
an angled front edge, located between the upper and lower mounting openings; and
a mounting channel having a lip on each end to engage a link;
wherein the feet, first links and second links form an integrated grid for mounting photovoltaic modules; and
a plurality of photovoltaic modules, each module having four mounting points, wherein the mounting points are attached to respective mounting openings in the tilt and mid-link brackets.
