Abstract: A method of forming a leakproof pitched wall or roof section with the use of solar panels includes arranging the solar panels in rows so that at least one panel on the second row is offset upwardly relative to at least one panel on the first row. Seals are provided to prevent the leakage of liquid through the pitched wall or roof section formed by the solar panels.

Abstract: At least first and second rows of panels may be mounted onto, or to form, at least part of a pitched roof, wall or other structure by mounting a panel support framework onto an underlying structure and arranging the panels so that each panel on the second row is offset upwardly relative to each panel on the first row in a stepped fashion.

Abstract: Underlying surface lift systems and methods are disclosed that facilitate the lifting and moving of constructions, including but not limited to structures, and machines, implements, building materials, earth, rock, and other massive massively weighted and/or large dimensioned objects or materials. The underlying surface lift systems and methods may be used or performed in combination with one or more support elements to the construction or other item to be lifted, such as steel I-beams or wooden beams or other supportive elements. The invention comprises in some embodiments underlying surface lift systems and methods, alone or in combination with or performed with supportive elements generally, such as beams and other devices or elements. Further embodiments may include an underlying surface lift apparatus having a support plate and a lift device in adjustable connection with the support plate. In some embodiments a pivot saddle is the adjustable connection of the support plate and the lift device.
