A cam-actuated connection device joins rail mounting members of a photovoltaic panel array. The connection device slides within channels of mounting members until the members are in a properly positioned grid. When in position, the connection device is rotated to lock the mounting members in a rigid grid network. The connecting device can be subsequently loosened, repositioned and locked into position. The rail-mounting members create a grid for installation of multiple PV panels. The mounting rail allows the unit to remain relatively compact in nature but still covers a wide range of PV panel thicknesses. The rail system has a hinged connection with the mounting rail that allows an installer to assemble the module in a near perpendicular fashion to the mounting rail, make the required electrical connections and then lower the PV module into its working position. The unit is then locked into its working position.

A photovoltaic panel mounting system utilizes rubber tires to anchor and position photovoltaic panels to face the sun and resist wind forces. The shaded interior cavity of the rubber tires physically and thermally protects electronics and batteries. The tires may be filled with soil, concrete, water, or aggregate to provide further ballasting, enabling a photovoltaic mount system to withstand high velocity winds. Telescoping conduits may house wiring for the system and allow for resizing and reshaping of the mounting system. The mounting system decreases used tire waste and provides low cost components and portability.

Photovoltaic mounting systems having sealant injection system are provided herein. Such sealant injection systems provide improved directional control of sealant flow and improved sealing of roof penetrations during mounting with one or more fasteners. Such systems can include a bracket assembly having a removable sealant injection package. The sealant injection package includes a collapsible sealant injection reservoir and is adapted to provide directionally controlled release of sealant upon collapse. Such a system can further include sealant injection guides that direct flow of sealant during mounting and pads or caps that cover and enclose the injected sealant so as to ensure adequate sealing of any roof penetrations and maintain its integrity over time. Such systems further allow for sealant injection packages to be interchanged or replaced as needed and allow for ready removal or replacement of the bracket after mounting while maintaining the seal of any roof penetrations.

A two-piece rooftop photovoltaic mounting system. A fixed base portion is attached directly to a roof surface via a lag bolt or other mechanical fastener. A movable portion is attached to and pivots about the base portion providing freedom of movement radially and axially with respect to the base portion. A photovoltaic module coupler is attached to the movable portion to support at least two photovoltaic modules at a location dictated by positioning of the movable portion. A locking nut locks the movable portion to the base portion at the desired location. A sheet of sealant material under the base portion helps prevent ingress of water into the roof surface via the lag bolt.

Photovoltaic mounting systems that form chemical flashings are provided herein. Such mounting systems can include a mounting plate adapted to interface with an off-the-shelf mounting puck so as to allow mounting of the puck on the roof surface without use of traditional roof flashing and/or modification of shingles of the roof surface. Such mounting plates can include a top surface adapted to interface with the puck and a bottom surface that defines a cavity between the mounting plate and the puck in which to form the chemical flashing by injecting a flowable sealant into the cavity via an inlet of the mounting plate that remains accessible from outside the puck during mounting. Such mounting plates can further include features for orienting the plate, directing runoff away from any sealed roof penetrations and filling of the cavity with flowable sealant.

Photovoltaic mounting systems having sealant injection system are provided herein. Such sealant injection systems provide directional control and containment of sealant flow providing improved sealing of roof penetrations of a mounted roof anchor. Such systems can include an anchor having a base and mechanical fastener and a sealant injection package, which includes a collapsible sealant injection reservoir and is adapted to provide directionally controlled release and containment of sealant upon tightening of the mechanical fastener into the roof surface. Such systems can include a sealant carrier that fits into an underside cavity of the anchor base and isolates the sealant injection package from anchoring load paths. The carrier can also define a flow path and sealant area in an underside recessed portion defining a cavity between the carrier and roof surface to provide a more uniform consistent sealant flow to form a chemical flashing about any roof penetration.
