Solar array system for covering a body of water
Systems and methods for supporting a solar panel array are disclosed, with embodiments specifically directed to spanning bodies of water such as aqueducts, canals, or other waterways. Cable truss assemblies are used to support panel receivers and solar panels mounted over the panel receivers. The cable truss assemblies are supported on groups of columns or other vertically extending support members anchored in the ground. Cable anchor lines may supplement anchoring and support of the installed solar panel array. Embodiments of the system include various combinations of supporting cables making up the cable truss assemblies. A method is also provided for construction of the solar panel array. Lengthy and continuous spans of the solar panel array can be installed over waterways by use of the cable truss assemblies. The solar panel arrays produce power, and simultaneously reduce evaporation from the waterways, resulting in conservation of water.
1. A solar panel array comprising:
a plurality of panel receivers each having a plurality of solar panels mounted thereto, said solar panel array having a length and a width;
a plurality of columns positioned at exterior edges of said solar panel array;
a pair of spaced apart cable truss assemblies, each cable truss assembly including a first support cable and a second support cable each extending between respective columns, and a plurality of compression members interconnecting said first and second support cables, said first and second support cables being vertically oriented with one another;
said panel receivers connected to and supported by said pair of spaced cable truss assemblies; and
a plurality of anchor cables connected to and extending from said respective columns; and
an extension support assembly includes a plurality of extension supports extending vertically, and an upper lateral support interconnecting upper ends of said extension supports.
2. An array, as claimed in claim 1 , wherein:
said compression members interconnect said first and second support cables along a center area of said cable truss assembly between said crossing points, and said center area between said first and second support cables having a generally elliptical shape.
3. An array, as claimed in claim 2 , wherein:
said first and second support cables diverge from one another as the cables extend laterally beyond said crossing points.
4. An array, as claimed in claim 1 , wherein:
said solar panels extending over said solar array are mounted to the array in three convex shaped areas, a first convex area located over a center area, and two lateral convex areas located on opposite lateral sides of said center area.
5. An array, as claimed in claim 1 , further including:
a plurality of cantilevered supports connected to corresponding cable truss assemblies, said cantilevered supports extending laterally beyond said cable truss assemblies for extending a length to which said panel receivers and solar panels may be mounted.
6. An array, as claimed in claim 1 , wherein:
each said cable truss assembly includes a plurality of cable truss assemblies spaced from one another longitudinally along the length of the array, said cable truss assemblies extending substantially parallel to one another, said plurality of panel receivers extending between adjacent pairs of said cable truss assemblies.
7. An array, as claimed in claim 1 , wherein:
said plurality of columns include a group of interior columns and a group of exterior columns disposed on each opposite lateral side of said array, such that said cable truss assembly is supported at one lateral side by a first pair of interior and exterior columns, and supported on the opposite lateral side by a second pair of interior and exterior columns.
8. An array, as claimed in claim 1 , wherein:
said compression members extend in an alternating diagonal pattern laterally across said cable truss assembly.
9. An array, as claimed in claim 1 , further including:
an evaporative barrier mounted to the array to minimize evaporative losses.
10. An array, as claimed in claim 9 , wherein:
said evaporative barrier includes a waterproof membrane or fabric extending over a selected area under the solar panel array.
11. An array, as claimed in claim 1 , wherein:
said first support cable has a first curvature, said second support cable has a second opposite curvature, and said first and second support cables crossing one another and connected to one another along two lateral crossing points spaced along a span of the cable truss assembly.
