Abstract

A method for producing a solar photovoltaic panel with an embedded RFID, and resultant product, are disclosed. A layup is formed of at least a first lamination layer and a plurality of electrically connected solar photovoltaic cells. At least a second lamination layer is added to the layup, and a lamination process is applied, forming a solar photovoltaic panel. An RFID tag is embedded in the panel before, during or after applying the lamination process. The RFID tag may be embedded between a front layer and a back layer, between sheets of ethylene vinyl acetate, between a backside of the layup and a junction box, or in an adhesive, sealant or polymerizing material. A solar photovoltaic panel with an embedded RFID tag is thereby formed. Instantiation information pertaining to the individual solar photovoltaic panel, including installation location information or test information, and product information are stored in the RFID tag.

Claims

1. A method for manufacturing an identifiable solar photovoltaic panel, the method comprising:

forming a layup of at least a first lamination layer, a plurality of electrically connected solar photovoltaic cells and at least a second lamination layer;

applying a lamination process to the layup thereby forming a solar photovoltaic panel;

embedding an RFID tag in the solar photovoltaic panel before, during or after applying the lamination-process thereby making a solar photovoltaic panel with an embedded RFID tag;

storing product identification information in the RFID tag pertaining to a product of which the solar photovoltaic panel is an individual item; and

storing instantiation information in the RFID tag pertaining to the individual item, the instantiation information including installation location information or test information.

2. The method of claim 1 wherein:

the at least a first lamination layer includes the RFID tag and a back layer of ethylene vinyl acetate;

the at least a second lamination layer includes a front layer of a transparent glass; and

the solar photovoltaic cells and the RFID tag are placed between the back layer and the front layer before or during the lamination process.

3. The method of claim 1 further comprising:

sandwiching the RFID tag between a first strip of ethylene vinyl acetate and a second strip of ethylene vinyl acetate thereby forming a sandwiched RFID tag; and

placing the sandwiched RFID tag on the at least a first lamination layer.

4. The method of claim 1 wherein embedding an RFID tag in the solar photovoltaic panel includes:

placing the RFID tag on a backside of the solar photovoltaic panel;

covering the RFID tag with an adhesive, a sealant or a polymerizing material; and

placing a junction box on the RFID tag.

5. The method of claim 1 wherein the product identification information includes:

a product name, a product number, a warranty information or a module class.

6. The method of claim 1 wherein the instantiation information includes:

a serial number, a process information, a date code, test data, a customer ID, GPS coordinates or other installation location information, security information, data encryption information, an installation date, maintenance information, repair information or comments.

7. A method for manufacturing an individually identifiable solar photovoltaic panel, the method comprising:

setting up a layup of at least a first lamination layer;

adding a plurality of electrically connected solar photovoltaic cells to the layup;

adding an RFID tag to the layup;

adding at least a second lamination layer to the layup;

applying a lamination process to the layup thereby forming a solar photovoltaic panel with an embedded RFID tag as an instantiation of a solar photovoltaic panel product;

storing product identification information in the RFID tag pertaining to the product of which the solar photovoltaic panel is the instantiation; and

storing instantiation information in the RFID tag pertaining to the instantiation of the solar photovoltaic panel, the instantiation information including installation location information or test information.

8. The method of claim 7 wherein:

the solar photovoltaic panel includes a back layer of ethylene vinyl acetate and a front layer of a transparent glass; and

the solar photovoltaic cells and the RFID tag are added between the back layer and the front layer.

9. The method of claim 7 further comprising:

sandwiching the RFID tag between a first strip of ethylene vinyl acetate and a second strip of ethylene vinyl acetate thereby forming a sandwiched RFID tag; and
