A solar racking system’s strength is determined in part by the metal racking, but it also depends on the roof’s underlying structure. Rafters and any supporting structures must be strong enough to withstand your region’s maximum wind and snow loads.

Scientists at Germany’s Fraunhofer Insititute for Solar Energy Systems (ISE) evaluated the performance of its newly introduced ‘Matrix’ approach to interconnecting shingled solar cells. The institute finds that, thanks to optimized current flows, energy yield of the Matrix approach could almost double that of standard shingled cell interconnection under random shading conditions.

Racking is the unsung hero of a PV installation, securing panels and protecting wiring while keeping the panels faceing the sun to ensure maximum energy yield. And innovations in the field help installers and developers to squeeze every available kilowatt-hour out of a project. Eric Wesoff and Tim Sylvia take a look at some of the latest products in the U.S. rooftop racking market.

The fixed coping has two vertical supports on either side of a locking channel. The vertical supports are biased or resilient to secure the coping to the secured bracket with the upper extensions providing full contact along the length of the vertical supports. The locking channel is configured to slidably receive a locking insert from a solar panel cap or light cap, each configured to connect to an adjacent cap such that they are electrically coupled.

A solar panel cap and light cap secured to a wall or parapet through the use of a fixed coping and a secured bracket. The secured bracket has a securing plate mechanically attached to a top of the wall and upper and lower extensions extending above and below the top of the wall along its sides. 

An adjustable tilt solar panel support system including a support post, a pivot bracket attached to the support post in a generally upright orientation and having a pivot pin hole for accommodating a pivot pin, and further having at least one adjustment opening; a rotational support cradle having a pivot pin hole in alignment with the pivot pin hole of the pivot bracket, such that the support cradle is pivotally attached to the pivot bracket, the support cradle further including at least one adjustment opening which aligns with the adjustment opening of the pivot bracket.An adaptable mounting system for mounting an LED display panel on an existing support structure for a billboard is provided, where the support structure including a plurality of posts having brackets arranged to support the billboard. The adaptable mounting system includes a lower arm and upper arms, each arm having a first end and a second end and one or more notches supported on the brackets of the existing support structure; a yoke coupled to the arms proximate the first end and configured for attachment to the LED display panel; and a brace coupled to one of the upper arms proximate the second end and coupled to the yoke of an arm beneath the one of the upper arms.A mounting system comprising at least one mounting assembly is disclosed. A mounting assembly is used to mount at least one solar panel. The mounting assembly includes a support base, a rotating base, a first motor assembly, a solar panel base and a second motor assembly. The rotating base is mounted on the support base and rotates about its vertical axis by the help of the first motor assembly, which is disposed between the rotating base and the support base. The solar panel base is coupled to the rotating base through a set of links, which transfers the rotation of the rotating base to the solar panel base. The second motor assembly is disposed on the rotating base and it provides a tilting movement to the solar panel base, which enables solar panel base to tilt at a plurality of angle from the horizontal surface of the rotating base.

 An adjustment pin is selectively inserted into and through the adjustment openings of the support cradle and pivot bracket to secure the support cradle at a selected angle, and wherein the removal of the adjustment pin permits the rotational support cradle to pivot on the pivot bracket about the pivot pin. Beam holders for securing support beams are disposed atop the rotational support cradle.

A modular system for providing bicycles at a given location according to configuration, the system comprising at least one bicycle rack for storing a bicycle, each bicycle rack comprising an electronic lock for removably securing a corresponding bicycle thereto, each bicycle rack further comprising a corresponding attaching means having an electrical connector operatively coupled to the electronic lock, an energy providing means for providing energy to each electronic lock, the energy providing means comprising a corresponding attaching means having a connector operatively coupled thereto and a structure to be installed at the given location, the structure comprising an elongated base, a plurality of spaced-apart rec
