An absorber system solves problems of known absorber systems for use in solar fields in that the absorber tube is suspended on a rail below an absorber cover. The design also makes it possible to move measuring and cleaning robots and the like along the absorber tube more and allows the absorber tube and the secondary reflector to be jointly suspended, whereby an exact mutual alignment between the two components is enabled.

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 solar panel mounting system forming an opening for holding solar panels therein for easy installation and removal and replacement. The system includes a plurality of support members adapted for positioning on a support surface. A roof panel is positioned on a top surface of adjacent support members and compressibly held in place by an astragal which is fastened to the support member sandwiching the roof panel between the astragal and the support member. A solar panel opening is formed between projecting portions on opposing sides of the roof panel which extend at an angle substantially perpendicular to a top surface of the support member.

Systems and methods for mounting solar panels include a curb assembly coupled to a top surface of a roof. An end of a solar panel rests on a portion of the assembly. An astragal is located with a portion of the astragal extending over the edge of the solar panel. A fastener is engaged through the astragal and the curb assembly such that a portion of the astragal contacts and compressively engages the top surface of the supported solar panel edge, whereby the solar panel is mounted to the roof.

A panel mounting device includes a mounting base with an attachment base plate for securing the base to a structure. The attachment base includes upright substantially parallel opposed compression walls extending from the base plate, wherein each compression wall includes a first outer surface and a second inner surface. The second inner surface of each compression wall includes a series of parallel ridges. The device further includes a securement rail device having a pair of relatively parallel primary exterior walls. The primary exterior walls include parallel ridges designed to releasably mate with the parallel ridges on the inner surfaces of each compression wall to releasably secure the securement rail device between the second inner surfaces of each of the parallel opposed compression walls, such that the securement rail device can be secured to the mounting base at different distances from the attachment base plate.

Watertight fastening devices and systems and methods for the employment thereof are disclosed. The disclosed watertight fastening device includes a head, a shank extending away from the head toward a distal end, and a cover extending outwardly and away from the head in the direction of the shank and defining a hollow region between the shank and an inner surface of the cover. The watertight fastening device may be used in conjunction with a solar power installation system that includes a base plate configured to be positioned against an installation surface. The base plate includes an aperture for receiving the shank of the fastener and protrusion surrounding the aperture configured to be received in the hollow region of the fastener, thereby providing an enhanced barrier against moisture reaching the installation surface.

A one-piece truss adapter for supporting single-axis trackers with truss foundations. A y-shaped structure has a pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a ball-shaped connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut holds the connector in place to complete the angularly adjustable assembly.

Embodiments of the present invention provide rigid attachment of materials using a roof mount, a cover, and a resilience constituent. A roof mount may have a top roof mount and bottom roof mount. A resilience constituent may be a ring, a disk with a middle ridge or even an arched disk or the like.
