Abstract: Improved masts for solar pile driving machines are provided that incorporate inline drilling as well as alignment and assembly devices that enable greater positional accuracy than possible with conventional equipment. In some cases, a jig, holder, or other device on the mast of the machine can be used to place a bearing assembly for a single-axis tracker while the foundation is being installed. Also disclosed are various multi-piece foundation piles that enable positional adjustment between below and above-ground components to compensate for misalignment.

Abstract: In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If a secondary condition is satisfied that guarantees sufficient pull-out strength, a new upper leg length may be selected and the driving operation terminated prior to reaching the desired embedment depth, reducing the amount of material necessary to construct the truss foundation.

Abstract: A method of embedding a threaded foundation component in ground with a layer of reactive soil with a combined drilling and driving machine includes: with an automated controller executing a control program, controlling the machine to begin an automated embedment operation to drive a threaded foundation component into a reactive soil; with the automated controller, controlling the machine to decouple a feed rate of the component from a rotary speed rate of the component to cause sheering of the soil around the foundation component by threads of the foundation component; and with the automated controller, controlling the machine to recouple the feed rate of the component to rotary speed rate of the component to reduce sheering of the soil around the foundation component by the threads of the foundation component until a target embedment depth for the foundation component is reached.

Abstract: A skirt for photovoltaic arrays provides a screen portion, a groove portion, and a separate coupling adapted to couple the skirt to the skirt of an adjacent photovoltaic array and to a photovoltaic module. Another embodiment provides a screen portion comprising an angled louver and is adapted to partially obscure an area substantially beneath a PV module in a PV array. A further embodiment provides an edge blocking skirt for a PV array comprising a screen portion adapted for mounting a bottom of the screen portion substantially close to a roof.

Abstract: A method, system and apparatus are disclosed regarding an attachment system for solar equipment, sometimes referred to as a flashing device allowing quick and easy assembling of the solar equipment into an array or other combination in a sturdy and durable manner. In examples of the present technology, a flashing device may include a flashing plate which may contain one or more raised features to further direct and control the flow of liquid over the flashing plate. The flashing device may also contain a fluid restrictor such as a seal or part of a seal usually held within an aperture of a block having a skyward facing essentially or substantially flat surface. One or more various items of solar equipment may be attached to the essentially flat surface of the block. Also disclosed are adjustable mounting feet which may be installed in connection with other solar equipment.
