Abstract

An invention is disclosed that shades a building from solar energy gain while simultaneously channeling intercepted energy in the form of heat and electricity for useful purposes. The invention includes modular units, each having several louvers that track the movement the sun to provide optimal shading, and optionally, lighting when the module is implemented as a skylight to allow daylight to pass through into the building interior. Each louver contains photovoltaic cells, a heat dissipating substrate to which photovoltaic cells are mounted, and an optional concentrator lens and/or reflector used to channel solar energy using inexpensive materials. Alternatively, th invention includes of stationary, modular units with reflective surfaces on the foreground that channel solar energy onto fixed solar receivers in the background. The effect is to avoid solar gain to the building surface and to concentrate solar flux onto solar receivers.
