An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress is provided. A first panel includes a sheet-like section, a receptacle connected to the sheet-like section, a first projection and a second projection. An interlock includes an interlock hook portion and an interlock receiving portion with the interlock configured to be inserted into the receptacle of the first panel and at least one of the interlock hook portion or the receptacle preventing the interlock from being withdrawn from the first panel. A second panel includes a sheet-like portion and a second panel hook portion configured to be inserted into the interlock receiving portion and engage with the second projection of the first panel. At least one of the second panel hook portion or the second projection preventing the second panel from being withdrawn from the first panel and/or interlock.

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.

A solar cell roofing system that includes a solar cell module including at least one solar cell that is laminated to a metal support sheet; and at least one bracket having a first type attachment point for engaging a standing seam of a standing seam metal roof and a second type attachment for engaging the metal support sheet of an adjacent solar cell module. During engagement of the solar cell module to the bracket, and engagement of the bracket to the standing seam, at least the metal support sheet is engaged in tension.

A metal roof construction provides a roof frame that includes multiple rafters. A plurality of clips or anchor plates are fastened to each rafter. Each anchor plate or clip has an anchor plate space surrounded by one or more plate members. The anchor plate has a plurality of spaced apart openings. A sliding anchor occupies the anchor plate space. Each sliding anchor has multiple spaced apart pedestals that extend from the anchor plate space upwardly through an opening. Multiple roof decking sections are mounted on the rafters. Each decking section extends under a part of the anchor plate. The anchor plate has one or more flaps that extend downwardly from the decking sections and next to a rafter. Fasteners attach each flap to a rafter.
