Solar panels create usable energy from the sun. The solar panel may use the sun to heat a fluid, such as water, flowing through the solar panel. The heated fluid can be used as a source of hot water or used in radiators to heat a building, such as a house. Alternatively, the solar panel may be a photovoltaic panel that converts the sun's energy directly to electricity. The electricity then is used to power a building. Photovoltaic panels require wires extending through the panel to carry the generated electrical power. The wires must be attached to the panels in a manner that is both secure and stable but also easily accessible and replaceable in the event that repair or upgrades are necessary.
Previous solar panels have addressed the issue of securing wires to a solar panel, particularly when a plurality of smaller solar modules are connected to one another to form the larger panel. One such panel is disclosed in U.S. Pat. No. 6,465,724 to Garvison et al. The panel has photovoltaic modules 106 having side rails and end rails fastened together to form a rectangular frame 162. An L-shaped flange 190 defines an outer electrical wire raceway 194 through which jumper cables 196 run and an internal electrical wire raceway 202 accommodating wires 164, 166. The raceways of adjacent modules join together to allow the wires to traverse the full extent of the panel. The wires are concealed, increasing the difficulty of accessing the wires when they are in need of repair, replacement or installation after the modules have been joined to one another.
US 2008/0006321 to Munch et al. discloses photovoltaic modules having a plate module 2 supporting a base body 3. The base body 3 contains a contact element 5 and connection cables attach to and extend from the contact element in the base body 3. There is no support between the base bodies for the connection cables so that the connection cables must have enough rigidity to support themselves. In addition, the base body is connected to the top surface of the plate module in an unspecified manner. However, the attachment method must be strong enough to secure the base body to the module.
There is a need in the art for a system and method of securing wires to solar panels in a stable and secure manner that allows the wires to be repaired, replaced or added in a simple manner requiring few or no tools and able to be accomplished in a minimal amount of time.
It is an object of the invention to provide a system for securing wires to a solar panel in a secure, stable manner that is easy to maintain.
It is another object of the invention to provide supports for guides, the guides extending about the solar panel with wires attached to the guides.
It is still another object of the invention to provide supports for a solar panel that are easily attached and removed from the solar panel.
These and other objects of the invention will be apparent to one of ordinary skill in the art after reading the disclosure of the invention.
The present invention provides a solar panel that includes an edge defining the perimeter of the solar panels, a plurality of guides extending over the solar panel for supporting or holding wires, the guides including a first guide and a second guide perpendicular to the first guide and at least one linear support connecting the first guide to the solar panel.
In one aspect, a right angle support connects the first guide to the second guide.
In another aspect, a plurality of modules are connected to one another to form the solar panel.
In another aspect, a frame extends about the perimeter of the solar panel, and the at least one linear support engages the frame to secure the at least one linear support to the solar panel.
In yet another aspect, the at least one linear support includes a body, an aperture extending through the at least one linear support for receiving a guide, and a groove extending across the body for receiving an edge of the frame.
In another aspect, the right angle support comprises a first aperture and a second aperture perpendicular to the first aperture.
In a further aspect, the right angle support further includes a first half and a second half, the first aperture formed by a first groove in the first half and a second groove in the second half, and the second aperture extending through the first half and the second half
The supports, to be described in more detail later, are easily attached at desired locations about the panel. Once the guides are secured to the supports, wires can be attached to the guides. The guides may be made of any suitable size, shape and material, such as a half inch aluminum rod. As seen in
The first support located near a corner of the panel is a linear support 30. A linear support is best seen in

Situations may occur where it is desired to add a right angle support to a guide that is already in place. While it is always possible to remove the guide in order to add a right angle support 40 to the guide, it would be advantageous to be able to add a right angle support to an existing guide without needing to remove the guide. For such situations, a two piece right angle support 50, seen in
The two piece right angle support 50 has a first half 52 and a second half 62. The first half has a first groove 54 and a first aperture 56. Similarly, the second half has a second groove 64 and a second aperture 66. Each half has connector screw holes 59 allowing a screw (not shown) to secure the two halves together. When the two halves are connected, the two grooves 54, 64 form an aperture and the first aperture 56 and second aperture 66 align with one another to receive a guide. The first half 52 has a threaded hole 58 for a set screw and the second half 62 has a threaded hole 68 for a set screw. As can be readily understood, the threaded holes can be provided in either half. The two piece construction of the support allows one half to be placed on one side of a guide and the other half to be placed on the other side of a guide and then connected to one another so that the guide is enveloped by the two grooves 54, 64. Once secured, the perpendicular guide can be attached to the support 50 by placing the guide within the upper aperture 66.
While the invention has been described with reference to a preferred embodiment, variations and modifications would be apparent to one of ordinary skill in the art. The invention encompasses such variations and modifications.
