NOVELTY - The window screen has a pair of generally horizontal frame members, each secured to the vertically oriented frame members of a screen frame (2). A screen material is secured to the frame, while a lower rail member is secured to the vertically oriented frame members. An upper rail member is oriented parallel to and in spaced relation with the lower rail member, with a solar collector (24) secured to the rail members to charge a battery operatively associated with a power outlet.    USE - Window screen for window assembly having integral energy collecting and charging system (claimed).    ADVANTAGE - Enables provision of a window or a door mounted solar system employable to charge a battery which in turn may energize a product through the use of a universal serial bus (USB) port. The solar charging system can be employed in a new constructions, replacement windows and doors, and field application. Reduces the cost of wiring electrical outlets for a building, thus reducing fire hazards and increasing the convenience of use. The system can be employed on windows and doors made from wood, aluminum, steel, vinyl, fiberglass and composites. The system can be used with movable and fixed pane windows as well as screens. The solar panel and screen can be readily retrofitted into existing windows. Enables provision of a solar box which may be secured within an opening of a deck such that the solar panels are exteriorly exposed as is a weatherproof power outlet. Provides solar collectors as part of a factory created structure or a retrofit in the end use environment with the solar collectors being angularly disposed for maximum efficiency of the collection of solar energy to energize a battery.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a window wall structure;    (2) a window assembly;    (3) a solar collecting structure;    (4) a solar collecting support structure;    (5) a solar box assembly; and    (6) a solar post cap assembly.    DESCRIPTION OF DRAWING(S) - The drawing shows the front elevational view of a rotatable window.    Screen frame (2)    Jambs (4,6)    Header (10)    Rotatable sash (14)    Solar collector (24)
