摘要:
A solar collector assembly may include a frame supporting a solar collector and a frame member defining a tilted pivot axis. Support struts may be used to elevate one end of the frame and may be pivoted between an orientation generally parallel to the frame member and to an orientation generally away from the frame. Anchorless, ballast type bases may be used to support the solar collector assembly. Several assemblies may be stacked on top of one another in a storage or transportation configuration using spacers extending between the frames.

摘要:
System and method for mounting one or more photovoltaic modules includes one or more flexible rods, including a first end and a second end opposite the first end, each of the one or more flexible rods further including an inner core and a first jacket surrounding the inner core between the first end and the second end. The first end is configured to be attached to at least one photovoltaic module using one or more first adhesive materials. The second end is configured to be inserted into at least one hole of a modular rail and attached to at least the modular rail using one or more second adhesive materials. The one or more flexible rods are configured to allow at least a lateral movement in a first direction between the photovoltaic module and the modular rail and support at least the photovoltaic module in a second direction.
摘要:
A frameless photovoltaic (PV) module system and methods secure solar panels directly to a fixed structure either individually or collectively as an array. Universal mounting brackets attached to the back of each solar panel module connect to one another and to mounting feet that anchor to the fixed structure. Mounting brackets interlock with mounting brackets on adjacent solar modules and include a quick release mechanism to connect to and disconnect from mounting feet appropriately selected for the given fixed structure or roof type.

A ballast system for roof membranes includes connected modules filled with loose-fill ballast and adapted to hold a predetermined volume of water for at least a predetermined period of time on the roof to control runoff.

A photovoltaic roofing assembly comprises a roofing membrane ( 102 ), a plurality of photovoltaic modules ( 104, 106, 108 ) disposed as a layer on top of the roofing membrane ( 102 ), and a plurality of pre-formed spacers, pedestals or supports ( 112, 114, 116, 118, 120, 122 ) which are respectively disposed below the plurality of photovoltaic modules ( 104, 106, 108 ) and integral therewith, or fixed thereto. Spacers ( 112, 114, 116, 118, 120, 122 ) are disposed on top of roofing membrane ( 102 ). Membrane ( 102 ) is supported on conventional roof framing, and attached thereto by conventional methods. In an alternative embodiment, the roofing assembly may have insulation block ( 322 ) below the spacers ( 314, 314', 315, 315 '). The geometry of the pre-formed spacers ( 112, 114, 116, 118, 120, 122, 314, 314', 315, 315 ') is such that wind tunnel testing has shown its maximum effectiveness in reducing net forces of wind uplift on the overall assembly. Such construction results in a simple, lightweight, self-ballasting, readily assembled roofing assembly which resists the forces of wind uplift using no roofing penetrations.

摘要:
A photovoltaic system includes a plurality of rectangular-shaped photovoltaic modules and a plurality of separate and spaced-apart support members supporting and orienting the photovoltaic modules in an array on the support surface without penetrating the support surface. The support members are formed of plastic and each of the photovoltaic modules is supported by at least four of the support members. Each of the support members is secured to and supports at least one of the photovoltaic modules but is not directly secured to any of the other support members. Thus the support modules can be utilized to support a wide variety of different sizes of photovoltaic modules. A wind shield is located at the rearward most support members. The wind shield is spaced a distance from the rearward photovoltaic modules and shaped to deflect wind up and over the array of photovoltaic modules.
摘要:
Pressure equalization between upper and lower surfaces of PV modules (14) of an array (12) of PV modules can be enhanced in several ways. Air gaps (32, 34) opening into the air volume, defined between the PV modules and the support surface (16), should be provided between adjacent PV modules and along the periphery (18) of the array. The ratio of this air volume to the total area of the air gaps should be minimized. Peripheral wind deflectors (20) should be used to minimize aerodynamic drag forces on the PV modules. The time to equalize pressure between the upper and lower surfaces of the PV modules should be maintained below, for example, 10-20 milliseconds. The displacement created by wind gusts should be limited to, for example, 2-5 millimeters or less.; For inclined PV modules, rear air deflectors (148) are advised for each PV module and side air deflectors (162) are advised for the periphery of the array.
摘要:
An assembly of, uniquely inter-connected modular parts form a high strength waterproof flexible membrane. The said membrane is restrained/positioned in the horizontal plane via a perimeter beam, with fixings on its exterior boundary to the storage parapet/berm, and through internal tendons to the PV panel super structure rows, whilst allowing unrestricted vertical movement in concert with the water level changes. This invention is intended to provide stability, reliability and durability under localised extreme weather conditions. The system may be mounted on a flotation pod or on a land based or building structure.
