Illustrative embodiments present a self-contained window system that includes a solar-generating glass window, pods that contain components, an energy storage device, and electrical circuits that distribute electrical power that is generated by the solar-generating glass and distributed to the components and the energy storage device. The self-contained window system is secured to a structure that may be a window frame, a glazing bead, or the like. In illustrative embodiments, the pods are secured inside of the structure, while in other illustrative embodiments the pods are secured on the outside of the structure. Regardless of whether the pods are secured inside or outside of structure, the components in the pods are accessible and easy to maintain. The pods and components can be conveniently exchanged and upgraded.
