A roof integrated photovoltaic system includes a plurality of photovoltaic panels each having a right end, a left end, a front edge, and a back edge. A right end coupler is secured to the right ends of at least some of the photovoltaic panels and a left end coupler is secured to the left ends of at least some of the photovoltaic panels. The right end couplers and the left end couplers are configured to interlock and form a seal when two of the plurality of panels are moved into end-to-end engagement with each other. At least one front edge coupler is affixed to at least some of the plurality of photovoltaic panels at the front edges thereof and at least one back edge coupler is affixed to at least some of the plurality of photovoltaic panels at the back edges thereof. The front edge couplers and the back edge couplers configured to interlock when two of the plurality of panels are moved into edge-to-edge engagement and a seal is positioned to prevent water from penetrating at the junction of a front edge of one panel and the back edge of an adjoined panel. Panels are installed on a roof in end-to-end and front edge to back edge relationship to form a photovoltaic array and are electrically interconnected to produce electricity when exposed to sunlight. Flashing and gap filling faux panels are provided as part of the system. In an alternate embodiment, a frame formed from individual rails surrounds and holds a frameless solar laminate and the frame also forms the coupling features.
