Solar panel junction box capable of integrating with a variety of accessory modules, and method of use
A junction box is affixed to, and electrically coupled with, a solar panel. The junction box is configured to releaseably engage and disengage accessory modules, thereby allowing accessory modules to be replaced or exchanged easily. Accessory modules are electrically coupled with other accessory modules in the solar panel string. The furthest downstream accessory module is connected to a wire harness, which is connected to a central combiner box.
1. A first interchangeable solar panel control system, said system comprising:
a solar panel;
a junction box including an engagement platform having at least one groove and at least one securing rib, said junction box affixed to said solar panel; and
an accessory module releaseably engaged with said engagement platform, said accessory module slidably engaged with said at least one groove and fixed to said at least one securing rib.
2. The first control system of claim 1 wherein said accessory module includes an industry standard interface.
3. The first control system of claim 2 wherein said industry standard interface includes two female module plugs, three clipping assemblies and two raised strips.
4. The first control system of claim 1 wherein said junction box is affixed to said solar panel by an adhesive.
5. The first control system of claim 1 wherein said accessory module further comprises a first input and a first output.
6. The first control system of claim 5 further comprising a second control system having a second input and a second output, said second control system downstream from said first control system, wherein the first output is connected to the second input.
7. The first control system of claim 6 further comprising a third control system having a third input and a third output, said third control system downstream from said second control system, wherein the second output is connected to the third input.
