Abstract: Disclosed is a window blind solar energy management system for capturing solar energy to manage illumination and temperature within a defined space. Blinds comprising curved louvers are hung from the internal frame of a window, each louver having a concave, highly reflecting specular mirrored surface that focuses incoming solar beam radiation onto a thin area on the back of the adjacent louver. The angle of the louvers is adjusted by an integral automatic controller so that the thin strip of light can be focused on one or two of three regions on the back of the adjacent louver which are designed to either reflect, absorb, or reject the incoming light.

Abstract: Methods, apparatus, and systems relating to the use and design of specially shaped, rotating reflective louvers to provide cost effectively harvesting of electricity, heat, and/or lighting are described. In an embodiment, the reflected and concentrated direct light is focused on the neighboring louver photovoltaic cells to generate electricity and an integral cooling channel allows heat collection. A skylight embodiment permits the indirect light to pass between the louvers and through a transparent backing providing high quality natural light inside while allowing artificial lights to be dimmed or turned off saving energy. In some embodiments, control systems (that may be computer controlled) can modulate the louver position to improve the light transmitted into the building when appropriate to maximize the net energy saved or generated depending on the situation. Moreover, the devices can be retrofitted into existing buildings or integrated into new building construction.

Abstract: A controller for an energy management system that controls the amount of light allowed into an area is provided. The system comprises a louver assembly and a light sensor contained within a light well. The light sensor is in communication with a controller that manages the position of the louvers in the system and controls the amount of light allowed through the system. The system further comprises thermal sensors in communication with the controller, which allow for management of the louvers' position to maximize energy efficiency.

Abstract: Methods and devices are presented that allow the harvest of electricity, heat and lighting simultaneously from a solar converter, often at less cost than conventional solar collectors. The converters use slats to intercept sunlight. Slat surfaces in the direct light path may be coated with photovoltaic (PV) material, or may be shaped to concentrate sunlight, allowing less PV material to capture reflected, concentrated light for improved economics. Forcing air flow past enclosed slats let the slats operate as PV heat sinks, heat absorbers, and heat exchangers capturing much of the solar energy that is not converted to electricity, as heat. Embodiments also allow passage of indirect light to supplement interior artificial lighting, often with positive aesthetic effects. These slatted apertures mitigate glare and overheating problems associated with typical skylights and some windows, allowing wider use as architectural elements.

Abstract: Disclosed is a housing and mounting assembly for a skylight module, and particularly for a skylight module that incorporates an energy management system. The housing and mounting assembly is configured to efficiently capture both direct solar and diffuse ambient light, and deliver light that is diffuse to the space below the skylight that provides even illumination and no unpleasant glare spots. The walls of the skylight module may be formed of multi-wall polycarbonate panels configured to redirect both the upward- and downward-shining light through the aperture into the space below. Moreover, the curb of the assembly may include a flexible flashing strip provided with a reflective coating configured to reflect sunlight upward through the walls of the assembly and into the skylight module, such that the advantages of collecting and using such reflected light can be achieved even in a retrofit installation on a non-reflective roofing surface.

Abstract: Disclosed is a system and method for harvesting solar energy, and more particularly an energy-positive sky lighting system that may provide an integrated energy solution to a variety of commercial buildings. A plurality of skylight modules are provided, each having a plurality of louvers configured to reflect incoming sunlight onto a thermal receiver area on an adjacent louver to heat a working fluid in communication with the louvers (i.e., such that heat transfer is carried out between the thermal receiver and the working fluid), all while allowing control of the amount of daylight that passes through the module. The modules are constructed such that the balance of the solar energy not going into day lighting is captured in the form of thermal heat, which in turn may be applied to building system cooling and heating applications.
