Abstract: A dual drive shaft solar tracker system comprises a photovoltaic (PV) structure, which includes at least one solar panel, a support structure and first and second drive shafts. The first and second drive shafts comprise first and second belt mechanisms wherein movement of the PV structure occurs by wrapping belts of the first belt mechanism onto the first drive shaft and by wrapping belts of the second belt mechanism onto the second drive shaft so as to provide a non-linear wrapping rate to accommodate the non-linearity of the belt wrapping onto the first and second drive shafts. A linkage, which ties two rows that are unbalanced in opposite directions, cancels out the imbalance as long as both rows have identical components. This allows trackers to use PV modules of any size and weight and the perfect balance is unaffected.

Abstract: Systems and methods are provided for supporting (racking) solar (e.g., photovoltaic) panels. At least one concrete track can be formed, first, second, and third racking structures can be assembled, each including two legs, landings at tops the legs, and feet that respectively can be secured to the at least one concrete track. A first solar panel can be placed on the landings of the first and second racking structures. A first edge of the first solar panel can be secured to each the landings of the first racking structure. A second solar panel can be placed on the landings of the second racking structure and on the landings of the third racking structure. A second edge of the first solar panel and a first edge of the second solar panel can be secured to each the landings of the second racking structure.

Abstract: Under one aspect, a system is provided for rotating photovoltaic modules arranged in a row. The system can include an elongated structural member extending along and parallel to the row; protrusions coupled to the elongated structural member; an actuator; and drive mechanisms coupled to the photovoltaic modules. Actuation of the actuator can move the elongated structural member, the movement of the elongated structural member can move the protrusions, the movement of the protrusions can move the drive mechanisms, and the movement of the drive mechanisms can rotate the photovoltaic modules.

Abstract: A Modular Roof Mounting System utilizes an assembly Jig that makes assembly of the structural units very easy and repeatable. The assembly Jig incorporates a photovoltaic panel mounting frame that the structure is required to support. In addition to the photovoltaic panel mounting frame it includes only two low cost universal components: two South rail locators and two North rail locators. The North and South rail locators are attached to the mounting holes in the panel frame, two on the South edge and two on the North, and produce a rail spacing that lines up with the same holes. The North Rail Locators have additional locating features to position the cross beams. Using a photovoltaic panel mounting frame to create a Jig that automatically determines the configuration of the Precision-Modular assembly and requires no adjustments and allows for the assembly of mounting structures for various photovoltaic panel geometries.

Abstract: A wire management clip formed of an elastic material to clip onto a structural element. The clip is formed to include an area for supporting a wire or wire bundle. Preferably, the clip includes holes formed on opposing sides to allow a strap attachment, such as a zip-tie, to hold a conduit or wire outside the clip.

Abstract: A dispenser sequentially dispenses a plurality of containers. The dispenser includes a housing having a front, a rear, a top, a bottom, a first side and a second side, with an inlet and an outlet for the containers being disposed on its front. A passage is disposed within the housing and guides the containers from the inlet to the outlet. A receiving door is connected to the housing and is movable between a closed position covering the inlet and an open position allowing the containers to be inserted into the inlet. The receiving door includes a front face contoured to cooperate with the passage to guide the containers to a predetermined orientation upon insertion into the inlet. The passage is also canted toward one side of the housing to maintain the containers in the predetermined orientation.
