Wheel carriage assemblies and related fabric deployment systems and methods are disclosed. A wheel carriage assembly comprising at least one wheel with ball bearings on the interior of each wheel, and a pivot point that allows for position independence, is configured with a hembar coupled to a piece of fabric to allow a surface of varying shape to be covered. The system provides the ability to cover both traditional window shapes as well as surfaces of irregular shape or inclined orientation, and reduces and evens the amount of wear on certain components to extend system life.

A skylight for a building includes a solar panel arranged within the skylight, the solar panel comprising one or more photovoltaic cells to collect direct radiation from rays of sunlight for conversion to electrical power, and an optical element to receive the direct radiation and refract it to the solar panel, and to receive the direct radiation and diffuse radiation scattered from the rays of sunlight and refract the direct radiation and the diffuse radiation through the skylight, bypassing the solar panel, to provide daylighting in the building.

A roller shade adapted to be installed in a non-rectangular structural opening comprising a roller tube, a shade material, a hem bar, and a pair of longitudinal side channels. The hem bar may be extendable and may comprise a pair of wheels at its opposite terminal ends. Each wheel is adapted to be retained by and travel within one of the longitudinal channels which are adapted to guide the hem bar assembly along the side jambs and control an extension of the extendable hem bar as the shade material is rolled on or unrolled from the roller tube and the distance between the side jambs changes. The roller shade may further comprise a pair of tension modules adapted to be attached to the hem bar proximate to one of the wheels to provide tension on the hem bar assembly.

Implementations of a roller blind assembly for angled architectural openings are provided. In some implementations, the roller blind assembly comprises a frame, a roller tube assembly, a roller blind sheet, a chain assembly, a track assembly, an extension assembly, a retraction assembly, and a motor assembly. In some implementations, a method of using the roller blind assembly comprises installing the roller blind assembly to fully fit the perimeter of an angled architectural opening and operating the roller blind assembly to fully cover the opening of the angled architectural opening.

According to some aspects, provided are curtain assemblies comprising two or more curtains selectably moveable between an open position and a closed position. Some embodiments include a track guide for at least one of the curtains having a first track and second track insert coupled to respective sides of the track guide and the curtain, wherein the curtain is moveably coupled to the first and second track inserts, and moveable along the channel of operation during transition between the open and the closed position. The curtains can be configured to define an air pocket that improved the energy efficiency of the curtain assembly (e.g., improving heat and/or noise properties). Some embodiments include a roller guide to maintain spacing between the curtains and can define a boundary of the air pocket.
