Description
- This application is a divisional application of, and claims the benefit of and priority to, U.S. patent application Ser. No. 14/073,767, filed on Nov. 6, 2013, entitled “Mounting Clips for Panel Installation”, which claims the benefit to Provisional Patent Application No. 61/807,416, filed Apr. 2, 2013, and Provisional Patent Application No. 61/806,203, filed Mar. 28, 2013, all of which are incorporated herein by reference in their entireties.
- The present invention relates generally to mounting means for photovoltaic panel installation systems. More particularly, the present invention relates to mounting clips for photovoltaic panel installation on a mounting structure that provides easy installation and electrical bonding.
- Photovoltaic panels are an environmentally friendly solution to generating electricity. However, they are an expensive solution, not only because of the cost of the photovoltaic panels themselves, but also because of the cost of installation of the photovoltaic panels. Typically, installation of photovoltaic panels requires highly trained installers and many hours of labor to properly align the panels and install them securely and accurately.
- The installation of a photovoltaic panel often requires mounting means to securely attach the photovoltaic panel to a secure structure. Such mounting means not only needs to be secure and stable, but also requires electrical bonding and simple installation procedure. The mounting means commercially available are difficult to install and require many different parts and tools to assemble the photovoltaic array. In addition, mounting means usually do not provide both mechanical fastening and electrical bonding of the photovoltaic panel.
- Therefore, what is needed is a photovoltaic panel mounting means which enables both mechanical and electrical bonding when installed, and provides for an easy installation process. This would result in a reduction of time and skill necessary to install photovoltaic panels on a mounting structure.
- The subject matter of this application may involve, in some cases, interrelated products, alternative solutions to a particular problem, and/or a plurality of different uses of a single system or article.
- In one aspect, a first mounting clip removably attaches one or more panels to a rail, both mechanically and electrically. The first mounting clip comprises a base having a leading edge and a trailing edge where the base is sized to fit on top of the rail. A plurality of locking clips is formed, extending upwardly away from the base towards the leading edge. Each of the plurality of locking clips provides upward force with regards to the base when pushed downwardly towards the base, acting like a spring. A central indexing tab is formed from the base uprightly and dividing the base in half lengthwise. The central indexing tab provides a z-direction guide for installing each of the one or more panels. At least two flanges are formed at each side of the base and angled downwardly away from the base. Each of the two flanges is configured to removably attach the base along each side of the rail. Further, a pair of lateral indexing tabs is formed uprightly along each side of the base where each of the pair of lateral indexing tabs is positioned and sized to receive one of the one or more panels in place. Each of the pair of lateral indexing tab further comprises a sliding slot defined between each of the pair of lateral indexing tab and the base having an opening end at the trailing edge. A vertical indexing tab is formed at each end of the pair of lateral indexing tabs, extending outwardly with respect to each of the lateral indexing tab at a perpendicular angle while the vertical indexing tab provides an x-direction guide for installing each of the one or more panels.
- In another aspect, second mounting clip comprises a base where a plurality of spring bonding tabs is formed. Each of the plurality of spring bonding tabs extends at an angle upwardly away from the base and rises towards the trailing edge. A top flange is formed above and parallel to the base at the trailing edge where the top flange prevents movement of or more panels in y-direction. A side flange is formed side of the base and angled downwardly away from the central indexing tab is formed from the base uprightly, dividing the base in half lengthwise. The central indexing tab provides a z-direction guide for installing the panels. Finally, a vertical indexing tab is formed at each side of the base at the leading edge. The vertical indexing tab provides a z-direction guide for installing each of the one or more panels in conjunction with the central indexing tab.
- In yet another aspect, similar embodiments and variations of an all direction-guided mounting means are further disclosed designed to fit a different configuration of a mounting structure. The mounting structure may include beams, rails, blocks, or the like.
