An electrochromic insert adapted to be fitted into an existing window frame allowing an existing window to be retrofit to have the benefits of electrochromics. The insert may have a scaffold that fits into a window frame. Securing the insert to the frame may occur through a variety of ways including a bracket, a flexible tab, a brace, a screw, a bolt, a projection, a detent, and an adhesive. The technology allows for the electrochromic insert to include an electrochromic device, energy collection device, an energy storage device, and an electrochromic device controller. Such a configuration may be considered autonoumous such that it need not draw power from another source. |
