Abstract

A method and device for cleaning and pretreating solar panels is provided. The device comprises a brush having cleaning elements made from silicone foam rubber material. The cleaning elements can be flaps of silicone foam rubber material. A sheet of silicone foam rubber material having two free ends can be attached to a core member such that the two free ends extend away from the core member to form flaps. The solar panels can be cleaned by brushing the solar panel surfaces with the flaps of silicone foam rubber material. The solar panels can also be pretreated by brushing the solar panel surfaces with silicone foam rubber material.

First claim

What is claimed is:

1. A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprising the steps of: providing a core member; providing at least one sheet of material, the at least one sheet of material being comprised of closed-cell silicone foam rubber and having a first free end portion, wherein the at least one sheet of material is attached to the core member with the first free end portion extending away from the core member; providing a flexible structural element disposed adjacent a trailing side of the at least one sheet of material, wherein the flexible structural element is configured to increase the pressure between the at least one sheet of material and the surface during the sliding contact, wherein the flexible structural element does not contact the surface during the cleaning, buffing, and/or polishing; and causing the core member to move in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern; wherein the sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.

2. The method of claim 1 , wherein the first direction is a rotational direction.

3. The method of claim 1 , further including the step of causing the core member to move in a second direction, wherein the second direction is a translational direction.

4. The method of claim 1 , wherein the surface is a solar panel and a light transmission characteristic of the solar panel is improved.

5. The method of claim 1 , wherein the core member includes a flat surface adjacent the attachment of each said sheet of material.

6. A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprising the steps of: providing a core member; providing at least one sheet of material, the at least one sheet of material consisting of closed-cell silicone foam rubber and having a first free end portion, wherein the at least one sheet of material is attached to the core member with the first free end portion extending away from the core member; providing a flexible structural element disposed adjacent a trailing side of the at least one sheet of material, wherein the flexible structural element is configured to increase the pressure between the at least one sheet of material and the surface during the sliding contact, wherein the flexible structural element does not contact the surface during the cleaning, buffing, and/or polishing and causing the core member to move in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern; wherein the sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.

7. The method of claim 6 , wherein the first direction is a rotational direction.

8. The method of claim 6 , further including the step of causing the core member to move in a second direction, wherein the second direction is a translational direction.

9. The method of claim 6 , wherein the surface is a solar panel and a light transmission characteristic of the solar panel is improved.

10. The method of claim 6 , wherein the core member includes a flat surface adjacent the attachment of each said sheet of material.

11. The method of claim 6 , further including the step of providing a second sheet of material, the second sheet of material consisting of closed-cell silicone foam rubber and having a first free end portion, wherein the second sheet of material is attached to the core member at a position opposite the at least one sheet of material, with the first free end portion of the second sheet of material extending away from the core member.

12. A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprising the steps of:
providing a core member;
providing at least one sheet of material, the at least one sheet of material being comprised of closed-cell silicone foam rubber and having a first free end portion, wherein the at least one sheet of material is attached to the core member with the first free end portion extending away from the core member; and
causing the core member to move in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern;
wherein the at least one sheet of material includes a second free end portion and a middle section disposed between the first and second free end portions, and wherein at least a portion of the middle section is attached to a C-channel groove of the core member and the first and second free end portions extend away from the core member, and
wherein the sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.

13. The method of claim 12 , wherein the first direction is a rotational direction.

14. The method of claim 12 , further including the step of causing the core member to move in a second direction, wherein the second direction is a translational direction.

15. The method of claim 12 , wherein the surface is a solar panel and a light transmission characteristic of the solar panel is improved.

16. The method of claim 12 , wherein the core member includes a flat surface adjacent the attachment of each said sheet of material.

17. The method of claim 12 , further including the step of providing a second sheet of material, the second sheet of material being comprised of closed-cell silicone foam rubber and having a first free end portion, wherein the second sheet of material is attached to the core member at a position opposite the at least one sheet of material, with the first free end portion of the second sheet of material extending away from the core member.

18. A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprising the steps of:
providing a core member;
providing at least one sheet of material, the at least one sheet of material consisting of closed-cell silicone foam rubber and having a first free end portion, wherein the at least one sheet of material is attached to the core member with the first free end portion extending away from the core member; and
causing the core member to move in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern;
wherein the at least one sheet of material includes a second free end portion and a middle section disposed between the first and second free end portions, and wherein at least a portion of the middle section is attached to a C-channel groove of the core member and the first and second free end portions extend away from the core member, and
wherein the sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.
