Methods of installing photovoltaic structures on a support element

1. A method of installing a photovoltaic structure on a support element having at least one first clip and at least one second clip, each of said clips being preassembled to the support element, each of said clips having a clip frame with a support area, a sidewall connected to the support area, and a top extension connected to the sidewall, each of said clips further having a holding element adapted to hold onto an edge portion of the photovoltaic structure, a length of the holding element of said second clip being shorter than a length of the holding element of said first clip, the top extension of each clip frame each comprising a top exterior surface and at least one structural feature located on the top exterior surface which cooperates with the respective holding element to hold the holding element in place with the clip frame, the method comprising:

inserting a first edge portion of the photovoltaic structure into the respective holding element of the at least one first clip mounted on said support element;

laying the photovoltaic structure parallel to the support element; and

sliding the photovoltaic structure towards the at least one second clip such that a second edge portion opposite to the first edge portion of the photovoltaic structure in inserted into the respective shorter holder element of the at least one second clip mounted on said support element opposite to said at least one first clip.

2. The method of claim 1 , wherein each of said holding elements is a C-shaped holding element comprising a vertical barrier abutting the sidewall of the clip frame and connecting one end of a top section to one end of a bottom section, the top section being in contact with an underside of the respective top extension, and the bottom section being in contact with a top surface of the support element, and each of said clips further including a fastening area for securing the clip to the support element, said fastening area comprising a flat middle section of the holding element extending perpendicularly from a lower end of the vertical barrier and in a direction away from the bottom section of the holding element.

3. The method of claim 2 , wherein the flat middle section of the holding element is located in between the support area of the frame and the support element.

4. The method of claim 3 , wherein the support area of the frame and the flat middle section of the holding element share a common opening for passing a fastener to attach the clip to the support element.

5. The method of claim 1 , wherein the at least one structural feature is at least one angled structure.

6. The method of claim 5 , wherein the at least one angled structure is at least one angled tooth.

7. The method of claim 1 , wherein each holding element comprises a vertically extending wall connecting a to section to a respective bottom section, and each of said top sections includes a curved element for engaging with the at least one structural feature.

8. The method of claim 7 , wherein each curved element forms a hook above the top section of each respective holding element.

9. The method of claim 1 , wherein after the second inserting step, the photovoltaic structure is engaged by said at least one first clip and said at least one second clip.

10. The method of claim 1 , wherein the photovoltaic structure is a carrier containing an array of photovoltaic modules.

11. The method of claim 1 , wherein the photovoltaic structure is a photovoltaic module.

12. The method of claim 1 , wherein the support element comprises at least 2 first clips mounted adjacent to each other and at least two second clips mounted adjacent to each other and opposite to said at least two first clips;

the inserting a first edge portion step is performed such that the first edge portion of the photovoltaic structure is simultaneously inserted into the respective holding elements of the at least two first clips; and

the inserting a second edge portion step is performed such that the second edge portion of the photovoltaic structure is simultaneously inserted into the respective shorter holding elements of the at least two preassembled second clips.

13. The method of claim 1 , wherein each holding element is a C-shaped holding element comprising a vertical barrier abutting the sidewall of the respective frame and connecting one end of a top section to one end of a bottom section, the top section being in contact with an underside of the respective top extension, the bottom section being in contact with a top surface of the support element, and a top surface of the bottom section having raised teeth protruding to resist photovoltaic structure movement, the raised teeth at least partially covering the a width of the bottom section.

14. The method of claim 1 , wherein the angle between the sidewall and the top extension is less than 90 degrees.

15. The method of claim 1 , wherein each of said holding elements is a C-shaped holding element comprising a vertical barrier abutting the sidewall of the clip frame and connecting one end of a top section to one end of a bottom section, the top section being in contact with an underside of the respective top extension, and the bottom section being in contact with a top surface of the support element, the length of the holding element bottom section being longer than the length of the respective holding element top section, and the length of the holding element top section of said second clip being shorter than the length of the holding element top section of said first clip.
