In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by rotating its base around a threaded connection until it locks in place so that a solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. An alternate embodiment of the apparatus is offered to support a rail-less pivot mount as well.

A mounting apparatus to secure a pair of solar panel rails to an asphalt shingle roof and minimize penetrations or damage to a rafter of the roof is provided. The mounting apparatus permits the solar panel rails to support adjacent solar panels thereon. The mounting apparatus includes a lower assembly coupled to the asphalt shingle roof and having a screw and flashing disposed on an asphalt shingle and coupled together, and an upper arm assembly coupled to the screw of the lower assembly and having a generally U-shaped member with a pair of upright arms continuously connected to opposing ends of a horizontal arm, each upright arm having a slot to receive a fastener that secures one of the pair of solar panel rails thereto.

A solar heat exchanger in which the manifolds are connected together using a threadless connection arrangement in which the end of one manifold tube carries at least two annular seals and the internal bore of the end of the adjacent manifold tube is cammed and when locked, the connection of the two manifolds is resistant to loosening when exposed to repeated thermal expansion and contraction cycles.

A retention apparatus, system and method is useful for attaching items, panels or other devices to a rail formed in longitudinal lengths and configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut including a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut, between an anchor latch of the rail and hook flange on the channel nut, and cooperating forces and movement of the biasing element secured to the channel nut.

A bonding clamp includes a top bracket including opposing side walls defining a channel therebetween. The top bracket has an aperture through a central portion thereof. The top bracket is shaped to receive a first photovoltaic (PV) module on a first side and a second PV module on a second side. A bottom bracket includes a body and a pair of top flanges extending vertically from a top surface of the body. The pair of top flanges are spaced apart from each other. The bottom bracket also includes anti-rotation flanges extending from a bottom surface of body. A fastening mechanism fastens the top bracket in a fixed position with respect to the bottom bracket.

A trestle includes a base, a slide bracket, a fixing unit, a first fastener, and a second fastener. The fixing unit is installed on the slide bracket and fixes a solar panel that is mounted on a surface of a roof surface. A mounting surface on which the solar panel is mounted is formed on a receiving member of the fixing unit. A fixing unit main body of the fixing unit is formed capable of holding down and fixing the solar panel to the mounting surface by the second fastener, and is fixed to the receiving member. The first fastener is attached such that the fixing between the slide bracket and the fixing unit can be released while maintaining the fixing between the receiving member and the fixing unit main body by the second fastener.

A roof mount assembly implements a stabilized fastener matrix which functions to stabilize the fastener connection with a roof. In one embodiment, a base has a one-piece construction with angularly spaced stepped bores. Roofing fasteners each having a flat head are receivable in the bores and securable therein. Plugs each having a flat lower surface are threadably engageable in the threaded bore wherein the flat lower surface of the plug engages the flat head of the fastener. In a second embodiment, the base has a two-part construction comprising a bottom plate and a top plate. The bottom plate has a plurality of arcuate slots which are angularly spaced from one another. Elongated fasteners are received in the slots. A top plate has a crown and a connector projects from the crown. The top plate mounts onto the bottom plate to provide a stabilized connection with the roof. The mount assemblies are also efficiently sealable with the adjoining roof. In one embodiment, the top plate and lower plate mount highly compressible sealant members.

At least one panel member is secured to a base member using a securing tool including a stand that holds a shaft having an external thread and restricts the axial movement of the shaft, a lower holder that has a center portion in which a cylindrical portion through which the stand is inserted is provided, and a first and a second placement surfaces which extend from the center portion, and an upper holder that has a flat plate portion through which a bolt hole portion and a tool hole portion are provided, a first and a second panel pressing portions which extend from the flat plate portion, wherein in the securing tool, a bolt inserted through the bolt hole portion is screwed with a first screwed groove formed in the center portion, and the external thread is screwed with a second screwed groove formed on the cylindrical portion.

Modular photovoltaic (PV) panel, system, and method of mounting. The system including a mounting flashing configured to mounted to a mounting surface and a folding PV panel. The folding PV panel including: a first subpanel including first PV cells, wherein the first subpanel extends along a first lateral plane and comprises a plurality of mounting hooks extending laterally from and affixed to a backside of the first subpanel, the mounting hooks configured to couple to the mounting flashing; a second subpanel including second PV cells, wherein the second subpanel extends along a second lateral plane, wherein the second subpanel comprises a front edge support configured to hold a front edge of the second subpanel away from the mounting surface; and a hinge assembly rotationally coupling the first subpanel and the second subpanel to allow an angle between the first lateral plane and the second lateral plane to change.
