Abstract: A solar energy collecting module includes a frame that is assembled without using screws. The peripheral frame components are joined together using locking links and one or more ribs extend along the back side of the solar panel and are coupled to opposed sides of the frame. The ribs are coupled to the frames by an edge key fastener that includes opposed first flanges and opposed second flanges, the first flanges separated from the second flanges by a gap. The edge key fastener is inserted into an opening formed in a side wall of a frame component and rotated such that the opposed first flanges are disposed behind the side wall and within the frame and the opposed second flanges are received in a corresponding cavity formed in each of opposed ends of the rib.

Abstract: A frame member is disclosed for a mounting a solar panel in a solar module. Embodiments of the frame member include an elongated outer sleeve having a channel configured for receiving an elongated inner reinforcing member disposed therein. The reinforcing member may be slidably inserted into the channel in some embodiments and is operable to structurally strengthen the outer sleeve. The reinforcing member may be made of a material having a greater tensile strength than the outer sleeve. A method for assembling the frame is also provided.

Abstract: A processing system including a vacuum chamber 24 and at least one tube 12 disposed through a wall 14 of the vacuum chamber 24 is described herein. A gas diffuser 22 is disposed in said tube 12, possibly at the end of the tube 12 and/or outside the chamber 24. The gas diffuser 22 is formed from a porous, possibly metallic, material which includes a plurality of microscopic holes whereby gas entering or leaving the vacuum chamber through the tube has a reduced force compared to if the gas diffuser 22 was not present. Other systems and methods are also disclosed.
