1. Technical Field
This disclosure relates generally to a solar panel installation and, more particularly, to apparatuses and assemblies for use in a ground mount solar panel installation on a flat roof.
2. Background Information
Large-scale solar panel arrays are currently provided with two major types of support systems. A first type is referred to as a roof system, which, as the name implies, embodies relatively light structures which are integrated with rooftops and roofing structures. These structures are limited in size as a function of rooftop areas and roof support capabilities.
A second major type of support system is referred to as a “ground system”, which, as opposed to roof systems, can be and often is quite extensive in area (solar panels provide energy as a function of areal sunlight capture and require large areas for viable energy production) and which are accordingly difficult to protect and are highly susceptible to weather conditions. In particular, high or sustained wind conditions may either damage solar panels over time or, more commonly, cause the panels to move out of optimal position for sunlight capture.
Typically, solar panel arrays comprise flat solar panels arranged on supporting structures usually of a fixed grid nature. The supporting structures are configured to hold the panels at an angle relative to the supporting ground such that the solar panels optimally face and capture sunlight for maximum energy conversion.
The structure of a solar panel array includes spaced apart pairs of vertical posts referred to in the art as north and south posts based on their positioning relative to sunlight direction. Other intermediate or otherwise positioned posts such as center posts may be and are often utilized in various support structures with north and south posts being the most common.
Because of the extensive area occupied by viable energy producing solar panels and the large number of panels typically used, efficiencies of scale and proper deployment present numerous problems.
According to an aspect of the present disclosure, a mounting system for mounting a solar panel is provided. The mounting system includes a plurality of mounting posts each configured to be driven into the ground leaving a first portion of the mounting post below ground and a second portion of the mounting post above ground. The second portion of the mounting post includes first and second opposing parallel sidewalls, a third sidewall extending between the first and second sidewalls, and a fourth sidewall extending between the first and second sidewalls and opposing and in parallel to the third sidewall. The fourth sidewall includes a longitudinal extending slot that faces in a magnetic north direction, with coaxial mounting through holes in the first and second sidewalls at a distal end of the second portion. A plurality of north-south beams are each mounted on the distal end of an associated one of the plurality of mounting posts and each having a north end and south end. Each of the north-south beams comprises a web and first and second flanges extending from the first web to form a first C-section. A first lip extends outwardly from a distal end of the first flange, and a second lip extends outwardly from a distal end of the second flange. The first and second flanges include first coaxial beam mounting through holes, and include second flanges and second coaxial beam mounting through holes. The first coaxial beam mounting through holes are located closer to the north end than the second coaxial beam mounting through holes, where for each of the north-south beams the web is placed over the distal end of the associated mounting post such that the first coaxial mounting through holes coaxially align with the coaxial beam mounting through holes. A first fastener extends through the first coaxial mounting through holes coaxially aligned with the coaxial beam mounting through holes to fasten the north-south beam to its associated one of the plurality of mounting posts. The mount may include a brace that includes a first end and a second end, where the first end is fastened to an associated one of the plurality of mounting posts and the second end is fastened to an associated one of the plurality of north-south beams via a second fastener and the second coaxial beam mounting through holes. A plurality of parallel purlins may be transversely fastened to a plurality of the adjacent north-south beams.
A roll strap may tautly connect between the parallel purlins and an associated one of the plurality of north-south beams.
The coaxial beam mounting through holes may be located in the first and second flanges at a location that leaves a longer length of the north-south beam on a south side relative to the mounting post when the north-south beam is mounted to the mounting post.
The foregoing features and the operation of the invention will become more apparent in light of the following description and the accompanying drawings.
The mounting system also includes a plurality of north-south beams, such as for example the beam 12 illustrated in
A first fastener 56 extends through the first coaxial mounting through holes 48 and the aligned coaxial beam mounting through holes 30 to fasten the north-south beam 12 to its associated one of the plurality of mounting posts 10.
The brace 14 (
The coaxial beam mounting through holes 48 located in the first and second flanges 40, 42 may be located a location on the beam that leaves a longer length of the north-south beam 12 on a south side relative to the mounting post 10, when the north-south beam 12 is mounted to the mounting post 10.
In one embodiment a solar panel may be fastened to at least two of the plurality of parallel purlins.
The post, beam, and brace may be made of galvanized steel (e.g., G90). However, it is contemplated that any high strength, non-corrosive, weather resistant material, including metallic (e.g., magni coated or stainless steel) and non-metallic materials may be used.
An exemplary embodiment of such a solar panel installation is the Max-Span™ post system designed by the assignee of the present invention, GameChange Racking of New York City, N.Y. Of course, the solar panel installation of the present disclosure is not limited to the specific exemplary embodiment detailed in herein. For examples, one or more system components may be swapped out for components with alternate configurations, one or more the components may be omitted and/or the mounting system may be modified to include one or more additional components not specifically described herein.
While various embodiments of the present invention have been disclosed, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the invention. For example, the present invention as described herein includes several aspects and embodiments that include particular features. Although these features may be described individually, it is within the scope of the present invention that some or all of these features may be combined with any one of the aspects and remain within the scope of the invention. Accordingly, the present invention is not to be restricted except in light of the attached claims and their equivalents.
This application claims priority from the provisional application designated Ser. No. 62/250,069 filed Nov. 3, 2015 and entitled “Max-Span N Ground System for Solar Panel Installations”, and is hereby incorporated by reference.
