NOVELTY - The method involves installing a solar roof truss including a non-structural top chord placed above a structural top chord where the truss accommodates weight of a solar panel assembly after a removable portion of the non-structural chord is removed. A set of end surfaces facing and spaced apart from a pair of sides of truss is provided, where a recessed space having dimension defined by length of portion, height between two upper surfaces of the chords and width spanning between the surfaces when the portion is removed. The space is utilized to hold the assembly.    USE - Method for installing solar energy panels on a roof of a building with a rooftop solar energy system during or after construction of the building by utilizing a roof truss i.e. solar roof truss, of a roof truss system (all claimed) i.e. solar roof truss system. Uses include but are not limited to residential building, commercial building, warehouse and carport.    ADVANTAGE - The method enables structurally designing the truss for supporting the assembly without the presence of the non-structural top chord. The method enables providing a panel enclosure having an air space underneath one of the panels to allow cooling of air flow and water drainage. The truss is pre-engineered to house the assembly and support the weight of the assembly, thus reducing retrofitting cost if the panels are installed. The non-structural chord can be configured into multiple standard roof truss designs, thus allowing a visually appealing solar rooftop system to accommodate a set of solar components without requiring a custom or specialized system. The truss is amenable to various sizes of solar arrays. The method enables providing a flashing integral with the panel enclosure to reduce manufacturing and installation costs of the system. The systems can be inexpensively standardized and easily installed while maintaining reliability and maintainability of the system.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a roof truss system for a set of solar energy panels.
