A solar panel awning device may include a solar panel having first and second opposing ends, first and second opposing sides extending between the first and second opposing ends, and first and second opposing major surfaces. The first major opposing surface defines a photovoltaic surface. The solar panel awning device may include first and second arms respectively coupled to the first and second opposing ends of the solar panel, and an actuator coupled to one of the first and second arms and configured to switch the solar panel between an extended position and a retracted position. In the retracted position, the solar panel is flat against a side of a building; in the extended position, the first opposing side is proximal to the side of the building and spaced apart from the side of the building; and the second opposing side is distal to the side of the building.

A sunshade is provided that is intended to be attached to a building by supports arranged along an inner side, so as to protect the building from solar radiation. The sunshade includes a fixed part equipped with supports, and a moving part guided by guide members that allow the sunshade to be moved toward the fixed part in order to obtain an overlapping of these parts under the effect of a motorizing system, these two fixed and moving parts accepting photovoltaic cells.

A pergola comprising a base module having a quadrangular support structure provided with vertical uprights connected to each other by at least one pair of rails and at least one transverse crossbeam connecting the pair of rails. The base module delimits a first roof surface. The pergola includes an extension module having a framework provided with at least one pair of struts. Each strut is at least partially vertically superposed on a corresponding rail, and is provided with at least one support leg that supports the overhanging framework on the side opposite the base module in the longitudinal direction. The extension module delimits a second roof surface at least partially superposed on the first. A guide structure is interposed between the struts and the rails for guiding a reciprocal longitudinal translation between the base module and the extension module, to modify the overall roof surface of the pergola.

A external light control device for equatorially located building utilizes tilting external light shelves that are capable of tilting backward (toward the building) from a vertical orientation to reflect low am (or late pm) sun away from occupants, but are deployed at a tilt away from the building exterior to capture more sun closer to noon time. The structure preferably integrate IR rejecting coating for incident light which is re-directed by TIR surface disposed normal to the thin film layers in a multi-layer IR reflective coating. The panel may be monolithic or comprise tilting louvers, which can be metallic, dielectric, or TIR reflectors. The louvers preferably also tilt in response to the determined sun position with the panel to optimize light utilization.
