This invention relates to system and method for support of a solar canopy.
Solar energy is a clean, renewal energy source. Photo-electro voltaic cell technology is increasing rapidly and makes installation of solar collector panels housing the photo-electro voltaic cells more and more economically feasible. Beyond the photo-electro voltaic cell technology itself are the problems of placement and support of the solar collector panels. Large numbers of solar collector panels must be assembled in series to achieve useful power production. In remote areas these may be placed on the ground without interfering with land use. In more developed areas, it is desirable to place the solar collector panels such that the land may also be used for other purposes, e.g., for parking lots, school/office hallways, playgrounds, or sports fields. To achieve this requires an elevated structure to support the solar collector panels.
Prior known systems for elevated structures for supporting the solar collector panels are inefficient and overly expensive since they require excessive amounts of materials, particularly steel support elements. Also, known systems take an excessive amount of time to install since welding together of the components is required on site.
It is desirable to have a method and system which overcomes the deficiencies of known systems. The instant invention provides such a solution.
The invention includes a solar canopy support system comprising: at least two substantially horizontally disposed “C”-channel support beams for supporting at least two “C”-channels, and at least two “C”-channels for supporting at least one solar power array and fixedly attached to the at least two “C”-channel support beams, each “C”-channel having a first end disposed at an upper portion of one “C”-channel support beam and having a second end disposed at an upper portion of another “C”-channel support beam, each “C”-channel comprising a longitudinal axis substantially perpendicular to the longitudinal axis of each “C”-channel support beam.
In another embodiment, the invention includes a solar canopy support system comprising: at least two beam support columns, each beam support column having a first end connected to a ground surface and extending substantially vertically along a longitudinal axis from the first end to a second end; a “C”-channel support beam disposed at the second end of each beam support column, the “C”-channel support beam comprising a longitudinal axis within about 0 degrees to about 30 degrees of perpendicular to the longitudinal axis of each beam support column; at least two “C”-channels, each “C”-channel having a first end disposed at an upper portion of one “C”-channel support beam and having a second end disposed at an upper portion of another “C”-channel support beam, each “C”-channel comprising a longitudinal axis substantially perpendicular to the longitudinal axis of each “C”-channel support beam; and at least one solar power array disposed on an upper portion of at least two “C”-channels.
In another embodiment the invention includes a method of mounting a solar canopy comprising: affixing at least two beam support columns to a ground surface, each beam support column having a first end connected to the ground surface and extending substantially vertically along a longitudinal axis from the first end to a second end; affixing a “C”-channel support beam to the second end of each beam support column, the “C”-channel support beam comprising a longitudinal axis within about 0 degrees to about 30 degrees of perpendicular to the longitudinal axis of each beam support column; affixing at least two “C”-channels to the at least two “C”-channel support beams, each “C”-channel having a first end disposed at an upper portion of one “C”-channel support beam and having a second end disposed at an upper portion of another “C”-channel support beam, each “C”-channel comprising a longitudinal axis substantially perpendicular to the longitudinal axis of each “C”-channel support beam; and affixing at least one solar power array to an upper portion of the at least two “C”-channels.
These and other features and advantages of the present invention will be made more apparent through a consideration of the following detailed description of a preferred embodiment of the invention. In the course of this description, frequent reference will be made to the attached drawings.
The beam support columns 120 supports “C”-channel support beams 130. The “C”-channel support beam 130 supports at least two “C”-channels 140. This provides the solar canopy support system for supporting a solar power array 150. The solar power array is a plurality of solar panels which may be attached to the “C”-channels 140 by any method now known or later developed.

In both
The angled hook section 1440 together with riser section 1420 secures the anchor member from movement perpendicularly to the longitudinal axis of the “C”-channel 140. A screw or nut and bolt are preferably installed through both the anchor member and the “C”-channel 140 to prevent any movement along the longitudinal axis of the “C”-channel 140. In a preferable embodiment a bottom portion of tab sections 1450 are attached to and substantially perpendicular to planar section 1420. In a preferable embodiment tab section 1450 are integral with planar section 1420. The two tab sections 1450 along the lateral axis of the anchor member 1310 are for providing proper spacing between the solar panels, i.e., to allow joining of the head member (1330 or 1320) and anchor member 1310. The two tab sections 1450 along the longitudinal axis of the anchor member 1310 are for aligning the solar panels by engaging in recesses (not shown) in the bottom of the solar panels as they rest on the “C”-channels 140.
The head member 1530 or 1520 is for clamping two solar panels between a bottom portion of the head member 1530 or 1520 and a top portion of the anchor member 1400. The head member is an elongated form including a plurality of sections. The sections include two substantially vertical planar riser sections 1520, each having a top end and a bottom end and being substantially parallel to each other. There is also a substantially horizontal joiner section 1530, for joining the two riser sections, having a left end and a right end, the left end of the joiner section adjoining the bottom end of one riser section, and the right end of the joiner section adjoining the bottom end of the other riser section, thereby forming a U-like assembly.
Also, there are two substantially horizontal planar clamping sections 1510, for clamping solar panels, each having a left end and a right end, the left end of one clamping section adjoining the top end of one riser section 1520, and the right end of the other clamping section adjoining the top end of the other riser section 1520; thereby forming a U-like assembly with flanges extending from the two top portions of the U-like assembly.
The head member 1530 or 1520 is removably fixed to the anchor member 1400, wherein a bottom portion of the solar power arrays rests on a top portion of the planar step section 1410 of the anchor member 1400, and a bottom portion of the planar clamping sections 1510 of the head member 1530 or 1520 rests on a top portion of the solar power arrays 150 (
The head member 1520 (
Anchor member 1400, in one embodiment is comprised of 14 to about 18 gauge sheet metal. Head members 1520 or 1530, in one embodiment are comprised of 12 to about 14 gauge sheet metal. In addition to sheet metal, either the head member or anchor member may be fabricated by other known materials and fabrication methods such as a cast metal, e.g., cast aluminum. Typical dimensions of the anchor member are from about 3.0″ to about 4.0″ wide, from about 3.5″ to about 4.5″ long, and from about 1″ to about 3″ tall. Typical dimensions of the head member are from about 1″ to about 3″ wide, from about 2″ to about 3″ long, and from about 1″ to about 3″ tall. These dimensions are not meant to limit the invention and the head member and anchor member in various embodiments may be adjusted to fit a wide variety of “C”-channels and solar panels.
Other embodiments of the present invention and its individual components will become readily apparent to those skilled in the art from the foregoing detailed description. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the spirit and the scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive. It is therefore not intended that the invention be limited except as indicated by the appended claims.
