Solar panel wind deflector
The invention relates to an aerodynamic wind deflector for use with pitched panels or structures mounted on horizontal, flat surfaces. More particularly, the invention relates to a wind deflector, including a contoured surface, for deflecting aerodynamic forces away from a pitched structure, such as a solar panel, mounted to a horizontal, flat surface, such as a roof top, wherein the structure is subjected to such aerodynamic forces. The wind deflector may further include a customized fin or fins as part of the design.
1. A method for reducing aerodynamic force impinging a roof-top solar panel, comprising:
a) providing a solar panel;
b) mounting the solar panel to a horizontal roof-top surface affected by aerodynamic forces;
c) positioning the solar panel at an angle to the surface of up to about 30°;
d) securing to one or both of the solar panel and the surface a wind deflector having a parabolic or elliptical curved profile, wherein the wind deflector has a width, w, that is at least equal to the width of the solar panel and a height, h, that is at least equal to the distance between the horizontal roof-top surface and a highest portion of the solar panel, and wherein the wind deflector further includes at least one fin; and
e) allowing the aerodynamic forces to encounter the wind deflector before encountering the solar panel.
2. The method according to claim 1 , wherein the aerodynamic forces result in the solar panel experiencing at least one of uplift and drag.
3. The method according to claim 1 , wherein the wind deflector deflects enough aerodynamic force to reduce uplift by at least about 50%.
4. The method according to claim 1 , wherein the deflector has a width and a height, and the width is longer than the height.
5. The method according to claim 1 , wherein the at least one fin of the wind deflector extends outwardly from a convex surface thereof.
6. The method according to claim 1 , wherein the fin is configured to extend from the aerodynamic force-facing surface of the wind deflector parallel to the horizontal surface for at least the full width, w, of the wind deflector.

a pitched structure secured to a horizontal surface, the pitched structure having a vertical height and a width; and
a wind deflector configured for mounting with the pitched structure, the wind deflector including at least one curved surface having a curve with either a parabolic or elliptical profile, wherein the at least one curved surface is configured to be positioned such that the curve is convex to the pitched structure and the at least one curved surface is configured to receive one or more aerodynamic forces before such aerodynamic forces encounter the pitched structure;
wherein the wind deflector has a width, w, that is at least equal to the width of the pitched structure and a height, h, that is at least equal to a distance between the horizontal surface and a highest portion of the pitched structure, and wherein at least one fin is configured to run parallel to the horizontal surface and the full width, w, of the wind deflector.
