1. An electrochromic system, comprising:

  • an insulated glass unit including a first glass pane and an electrochromic device having light transmissivity that is variable in response to an electrical current, wherein an external surface of the first glass pane lies along a first plane;

    a photovoltaic module electrically connected to the electrochromic device for providing the electrical current to the electrochromic device in response to light incident on the photovoltaic module, wherein;

    the photovoltaic module is mounted to the external surface of the first glass pane and is adjacent to an exterior building frame-work;

    the photovoltaic module has a light receiving surface that lies along a second plane that intersects the first plane and is oriented upward from a horizontal plane; and

    an electronics module in communication with either of the photovoltaic module or the electrochromic device.
