Abstract: Photovoltaic roofing systems including a roof pan, a photovoltaic device, and roof covering members. The roof pan is supported on a deck of a roof. The photovoltaic device is mounted to the roof pan and includes a photovoltaic panel. The roof covering members are mounted to the deck surrounding and overlapping the roof pan to define an integrated covering. The roof covering members overlapping the roof pan inhibits water flowing to the deck underneath the integrated covering. In some examples, the photovoltaic roofing system includes one or more of an inverter, an energy storage device, a wire retainer, and a roof cap.
