Abstract

A bracket is used for supporting at least one solar module each of which has a frame. The bracket includes a fastener, a holder and a fixing element. The fastener includes a top portion and extended portions connected vertically to both sides of the top portion. The top portion has a concave segment at its central position. The holder includes a supporting portion for resisting the bracket. The holder has first through holes, in which the extended portions pass through a plurality of second through holes of the frame and the first through holes of the holder for sandwiching the bracket between the fastener and the holder. The fixing element is used for fixing the fastener on the holder.

First claim

What is claimed is:

1. A bracket for supporting at least one solar module which includes a frame, the bracket comprising:
a fastener comprising a top portion and a plurality of extended portions connected vertically to both sides of the top portion, the top portion having a concave segment at its central position;
a holder comprising a supporting portion for holding the frame, the holder having a plurality of first through holes, wherein the extended portions are adopted for respectively passing through a plurality of second through holes of the frame and the first through holes of the holder for sandwiching the frame between the fastener and the holder; and
a fixing element for fixing the fastener on the holder.

2. The bracket of claim 1 , wherein the concave segment of the fastener has a first opening, and the holder has a second opening, thereby allowing the fixing element to pass through the first opening and the second opening for fixing the fastener on the holder.

3. The bracket of claim 1 , wherein the top portion of the fastener further has two supporting segments located at both sides of the concave segment for sandwiching the frame between the supporting segments of the fastener and the supporting portion of the holder.

4. The bracket of claim 1 , wherein the first through holes of the holder are elongated circular holes.

5. The bracket of claim 1 , wherein the amounts of the extended portions are two, and the amounts of the first through holes are two, thereby the bracket is adopted for fixing two sets of the frames of the solar modules.

6. The bracket of claim 1 , wherein the amounts of the extended portions are four, and the amounts of the first through holes are four, thereby the bracket is adopted for fixing four sets of the frames of the solar modules.

7. The bracket of claim 1 , wherein each of the extended portions further comprises a plurality of protrusions disposed at end of the extended portions.

8. The bracket of claim 1 , wherein the holder further comprises a restricting portion disposed vertically on an edge of the supporting portion and a plurality of protrusions disposed at the supporting portion.

9. The bracket of claim 1 , further comprising a supporting rack, wherein the supporting rack comprises a base, a junction portion and a triangular connecting portion connecting the base to the junction portion, wherein the supporting portion of the holder is adopted to be fixed to the junction portion by using the fixing element.

10. The bracket of claim 9 , wherein the supporting rack further comprises a supporting rib which is disposed inside the triangular connecting portion and is parallel to the base.

11. The bracket of claim 9 , wherein the supporting rack further comprises a reinforcing rib disposed inside the triangular connecting portion, wherein an angle between the reinforcing rib and the base is between 30° and 65°.

12. A solar system, comprising:
at least one solar module comprising a solar panel and a frame for fixing the solar panel, wherein the frame comprises:
a clamping portion for clamping the solar panel;
a protruding portion which is located at outside of the frame which is opposite to the solar panel and has a plurality of the first through holes; and
a connecting portion connecting the clamping portion to the protruding portion;

a fastener comprising a top portion and a plurality of extended portions connected and vertical to both sides of the top portion, the top portion having a concave segment at its central position;
a holder comprising a supporting portion for holding the frame, the holder having a plurality of second through holes corresponding to the first through holes of the frame, wherein the extended portions are adopted for passing through the first through holes of the frame and the second through holes of the holder respectively for sandwiching the frame between the fastener and the holder; and
a fixing element for fixing the fastener on the holder.

13. The solar system of claim 12 , wherein the concave segment of the fastener has a first opening and the holder has a second opening, thereby allowing the fixing element to pass through the first opening and the second opening for fixing the fastener on the holder.

14. The solar system of claim 12 , wherein the top portion of the fastener further has two supporting segments located at both sides of the concave segment for sandwiching the protruding portion of the frame between the supporting segments of the fastener and the supporting portion of the holder.

15. The solar system of claim 12 , wherein the first through holes and the second through holes are elongated circular holes, and a length of the extended portions is more than a thickness of the protruding portion of the frame.

16. The solar system of claim 12 , wherein the amounts of the extended portions are two, and the amounts of the second through holes are two, thereby the fastener and the holder are adopted for fixing two sets of the frames of the solar modules.

17. The solar system of claim 12 , wherein each of the amounts of the frames and the extended portions are four, and the amounts of the second through holes are four, thereby the fastener and the holder are adopted for fixing four sets of the frames of the solar modules.

18. The solar system of claim 12 , further comprising a supporting rack, wherein the supporting rack comprises a base, a junction portion and a triangular connecting portion connecting the base to the junction portion, wherein the supporting portion of the holder is adopted to be fixed to the junction portion by using the fixing element.

19. The solar system of claim 18 , wherein the supporting rack further comprises a supporting rib which is disposed inside the triangular connecting portion and is parallel to the base.

20. The solar system of claim 18 , wherein the supporting rack further comprises a reinforcing rib disposed inside the triangular connecting portion, wherein an angle between the reinforcing rib and the base is between 30° and 65°.
