A solar panel mounting base and system for solar panel installation uses a mounting base that is injection molded to include different connection locations which provide flexibility when installing solar panels to the mounting bases. Attachment clamps are secured to the mounting base using carriage bolts which are secured to the mounting base in an attachment well and allow the installer to attach solar panels from the top which makes installation easy and fast. The attachment clamps have a horizontal and vertical portion that use grooves to adjustably secure the two together when in the desired location. Ballast blocks are used to provide a non-invasive installation. In an array, multiple bases are used to provide the structure to support the solar array. Installers may vary the angle the solar panels form 5 degrees to 10 degrees by selecting the appropriate connection location.

The apparatus is for use with a concrete block and comprises a plurality of metal components. At least one of the components defines a lug. The plurality of metal components are coupled together in gripping relation to the block in use.

A slide-on spring damp for installing solar panels has a slide portion with a centrally located slot. The slot is used to attach the slide-on clamp to a solar panel mounting base using an attachment bolt that allows the installer to locate and secure a solar panel frame from the top without having to access the underside. The slide-on clamp has a clamp portion that has a reverse curve portion that curves back over itself to form a resilient gripping portion. The reverse curve portion has locking teeth located on the interior surfaces that lock the frame in place when inserted in the slide-on clamp. A stop portion is disposed the end of the slide portion. The method includes inserting a slide-on clamp on opposite sides of the frame so that the frame has at least four slide-on clamps thereon and then securing them to the mounting bases.

A method for installing a solar collector can include slip-forming a concrete track including a groove; curing the concrete track; placing a foot of a support structure of a solar collector in the groove; and applying adhesive between the foot and groove. Curing the concrete track optionally can include maintaining wetness of the concrete track for a sufficient period of time after slip-forming the concrete track. The foot optionally can include at least one of an aperture and a tab, and the adhesive flows through the aperture or around the tab. A foot of a support structure of a solar collector also is provided. The foot can be configured to be inserted into a groove and comprising a back wall, a first side wall including a first side tab, a second side wall including a second side tab, a third side wall, a fourth side wall, and a bottom wall.

The method according to the invention for producing a prestressed concrete workpiece is characterized in that the prestress is created by a heat treatment, wherein the concrete and the reinforcement therefor are selected in such a way that, when cooling the concrete workpiece from an elevated temperature, the heat expansion coefficient of the concrete is less than that of the reinforcement, and in that, during cooling, the concrete and the reinforcement adhere sufficiently strongly to one another if, during cooling, the concrete is hydrated at least to such an extent in order to be able to expand the reinforcement on account of the different heat expansion coefficients, and in that the concrete, together with the reinforcement, is brought to the elevated temperature in such a way that and is hydrated during cooling at least to such an extent that it is prestressed by the reinforcement after cooling.

A building rooftop mounting structure including a sacrificial material that allows freedom of movement between itself and the rooftop as well as between itself and the mounting structure.

A support assembly for supporting one or more photovoltaic modules on a support surface, such a generally flat roof, is disclosed herein. The support assembly includes a ballast tray configured to accommodate one or more ballasts; at least one tubular member coupled to the ballast tray, the at least one tubular member configured to support one or more photovoltaic modules above a support surface; and at least one clamp member coupled to the at least one tubular member. In one or more embodiments, the support assembly further includes at least one channel member coupling said at least one tubular member to said ballast tray.
