Sunshade for building exteriors

A sunshade supporting a plurality of photovoltaic cells outside a window in a curtain wall, said sunshade comprising

• a) a connecting bracket suitable for attachment to a window mullion in a curtain wall and extending exteriorly thereof, said connecting bracket defining a plurality of apertures,
• b) a blade support strut attached to said connecting bracket at a first joint, said blade support strut supporting a plurality of louvered blades, said blade support strut including a hub defining a plurality of holes, said hub being fixed to said connecting bracket by fasteners extending through said holes and said apertures in the connecting bracket, and
• c) said plurality of louvered blades each including
• 1) a top wall supporting a photovoltaic, cell, and
• 2) a pair of opposed end portions each supported by said blade support strut at a second joint at a fixed profile angle preselected to optimize electricity production by said photovoltaic cell, and
• 3) an electric cable for connecting said photvoltaic cell to an electric circuit.

A sunshade comprising

• a) two generally vertical, laterally spaced mullions,
• b) a connecting bracket attached to each said mullions,
• c) a blade support strut attached to said connecting bracket at a first joint, and
• d) a plurality of louvered blades each supported by the blade support strut at a second joint, said louvered blades being positioned on said second joint at a preselected fixed profile angle.
