Abstract

A roof pan with raised ridges along lateral edges, where the raised ridges of one pan cooperate raised ridges of another pan to prevent water movement. A formed edge that is offset from the roof surface when the pan is installed on the roof allows a flashing to slide under the formed edge when the roof pan is installed on the roof surface.

First claim

The invention claimed is:

1. A roof pan, comprising:
a planar surface;
a left tapered ridge along a first edge of the planar surface, and extending from a third edge of the planar surface to a fourth edge of the planar surface;
a right tapered ridge along a second edge of the planar surface, the right tapered ridge parallel to the left tapered ridge, the right tapered ridge extending from the third edge to the fourth edge, wherein the left tapered ridge of the roof pan overlaps the right tapered ridge of a second roof pan having the same configuration as the roof pan;
a first flange extending from the left tapered ridge along the first edge; and
a formed edge on the fourth edge, the formed edge having an offset away from a roof surface when the roof pan is mounted on the roof surface, the offset allowing a flashing to slide under the formed edge after the roof pan is installed on the roof surface.

2. The roof pan of claim 1 , wherein a mounting bracket is disposed over the left tapered ridge of the roof pan, wherein a fastener traverses through the top portion of the left tapered ridge to secure the mounting bracket to the roof surface.

3. The roof pan of claim 1 , further comprising a second flange extending from the right tapered ridge along the second edge, the first flange wider than the second flange.

4. The roof pan of claim 1 , further comprising:
a first chamfered corner at an intersection of the second edge and the fourth edge.

5. The roof pan of claim 4 , further comprising:
a second chamfered corner at an intersection of the first edge and the third edge, the second chamfered corner cooperating with the first chamfered corner of the second roof pan having the same configuration as the roof pan, to eliminate an overlap when multiple roof pans are installed on the roof surface.

6. The roof pan of claim 1 , wherein a distance between the left tapered ridge and the right tapered ridge corresponds to a solar module length.

7. The roof pan of claim 1 , wherein the left tapered ridge of the roof pan cooperates with the left tapered ridge of the second roof pan having the same configuration as the roof pan, when the roof pan is stacked on the second roof pan for shipping.

8. The roof pan of claim 1 , wherein the left tapered ridge of the roof pan overlaps the left tapered ridge of the second roof pan having the same configuration as the roof pan, when the second roof pan slides under the formed edge of the roof pan.

9. The roof pan of claim 1 , wherein the offset allows the third edge of the second roof pan having the same configuration as the roof pan to slide under the formed edge.

10. The roof pan of claim 1 , further comprising:
a second left tapered ridge along the first edge of the planar surface, the second left tapered ridge parallel to the left tapered ridge and between the left tapered ridge and the right tapered ridge.

11. The roof pan of claim 10 , further comprising:
a second right tapered ridge along the second edge of the planar surface, the second right tapered ridge parallel to the right tapered ridge and between the right tapered ridge and the second left tapered ridge.

12. The roof pan of claim 11 , wherein a distance between the left tapered ridge and the second right tapered ridge corresponds to a solar module length.

13. The roof pan of claim 11 , wherein the left tapered ridge and the second left tapered ridge of the roof pan overlap the right tapered ridge and the second right tapered ridge of the second roof pan having the same configuration as the roof pan.

14. The roof pan of claim 11 , wherein a mounting bracket spans across the left tapered ridge and the second left tapered ridge of the roof pan, wherein a fastener on either end of the mounting bracket traverses through each of the left tapered ridge and the second left tapered ridge to secure the mounting bracket to the roof surface.

15. The roof pan of claim 11 , wherein the left tapered ridge and the second left tapered ridge of the roof pan overlap the right tapered ridge of the second roof pan having the same configuration as the roof pan.
