Method and Apparatus for Forming and Mounting a Photovoltaic Array
The method and apparatus for forming and mounting a photovoltaic (PV) array of this invention is disclosed and provides, without limitation, (i) a PV module framing and coupling system which enables the attachment of PV modules to a roof or other mounting surface without requiring the use of separate structural support members which attach directly to and span between multiple PV modules in a formed PV array and (ii) an ancillary device attachment bracket, system, and method. One embodiment may provide a slidable parallel coupling for securely interlocking the outside surfaces of parallel frame members together in a side to side arrangement, thereby enabling the formation of a PV array with improved structural load distribution. Another embodiment may provide a photovoltaic module accessory bracket, comprising: a substantially rigid plate comprising a flexible spring tab; a first ear substantially rigidly positioned on the plate; a second ear positioned on the spring tab; wherein the spring tab flexes backward away from the plate during connection to a frame of a photovoltaic module to allow the first ear to engage the frame, and a forward force applied to the spring tab locks the second ear to the frame.
1 . Photovoltaic module accessory bracket, comprising:
a substantially rigid plate comprising a flexible spring tab;
a first ear substantially rigidly positioned on said plate;
a second ear positioned on said spring tab;
wherein said spring tab flexes backward away from said plate during connection to a frame of a photovoltaic module to allow said first ear to engage said frame, and a forward force applied to said spring tab locks said second ear to said frame.
2 . wherein said second ear cuts into said frame to create an electrical ground path between said frame and said accessory bracket.
3 . wherein said accessory bracket further comprises an inverter.
4 . wherein said accessory bracket further comprises electronic equipment.
5 . wherein said accessory bracket further comprises a channel for holding electrical wiring or wiring equipment.
6 . wherein said frame comprises a groove and said first and second ears lock into said groove when said accessory bracket is installed.
7 . wherein said accessory bracket connects to said frame without requiring a separate fastener.
8 . wherein said forward force causes said first ear to move downward into a final installed position.
9 . A photovoltaic module comprising:
a frame, said frame comprising an inside portion supporting a photovoltaic laminate and an outside portion accessible from a position adjacent to said photovoltaic module;
an accessory bracket supporting an electronic device and adjustably connected to said outside portion, said accessory bracket comprising a substantially rigid plate positioned adjacent to said outside portion;
wherein said accessory bracket is adjustably positionable along a length of said frame.
10 . wherein said accessory bracket snaps onto or into said outside portion.
11 . wherein said plate comprises a flexible spring tab, said spring tab flexing backward away from said plate during connection to said frame to allow a protrusion of said plate to engage said frame, and a forward force applied to said spring tab locks said spring tab to said frame.
12 . wherein said electronic device is an inverter or a power optimizer.
13 . A photovoltaic module accessory bracket, comprising:
a substantially rigid plate having an opening;
a low-turn fastener;
an accessory supporting portion for supporting an accessory device;
wherein said low-turn fastener comprises a key portion, said key portion permitting insertion of said key into a photovoltaic module frame in a first position and preventing rotation of said key inside said frame in a second position.
14 . wherein said low-turn fastener locks said accessory bracket to said frame with less than 120° of rotation from an insertion position.
DC: with approximately 90° of rotation.
15 . said low-turn fastener comprises a knob portion, said knob portion adapted to receive a tool for rotating said low-turn fastener.
