Aspects of the disclosure are directed to a multi-functional streetlight. In accordance with one aspect, the multi-functional streetlight includes a hexagonal shaped support structure, wherein the hexagonal shaped support structure includes an arm segment and wherein the arm segment includes a luminaire on an under side of the arm segment; and a base flange configured to couple the hexagonal shaped support structure to the ground.

A method for installing a solar collector can include slip-forming a concrete track including a groove; curing the concrete track; placing a foot of a support structure of a solar collector in the groove; and applying adhesive between the foot and groove. Curing the concrete track optionally can include maintaining wetness of the concrete track for a sufficient period of time after slip-forming the concrete track. The foot optionally can include at least one of an aperture and a tab, and the adhesive flows through the aperture or around the tab. A foot of a support structure of a solar collector also is provided. The foot can be configured to be inserted into a groove and comprising a back wall, a first side wall including a first side tab, a second side wall including a second side tab, a third side wall, a fourth side wall, and a bottom wall.

A system for mounting solar modules to a structure includes a first solar module, a rod, and a mount. The solar module includes a photovoltaic laminate and a frame circumscribing the photovoltaic laminate. The rod is connected with the frame. The mount is configured to couple at least the first solar module to a support structure. The mount defines an interior to receive the rod and an opening to the interior configured to permit the rod to pass through the opening. The mount includes a link selectively movable between an open position that permits access to the interior through the opening and a closed position that substantially covers the opening.

An integrated soundwall and renewable electrical energy generation system includes a series of metal fin tube foundations; a beam secured to each metal fin tube foundation, wherein the beam includes a lower portion extending into the interior of the metal fin tube and secured thereto, and each beam including channel forming elements; a series of solid fence panels inserted between adjacent beams, with each panel received within the channels formed by adjacent beams; and an electrical energy generator, such as a solar panel array, coupled to select beams above the solid fence panels. Inexpensive energy has always been a boon to spur economic development of a region, and the use of ecologically friendly sources is preferable. The design of the system allows for easy construction of parallel fences to multiply the energy generation with such parallel fences enhancing the barrier aspects of the fence system.
