Photovoltaic roof system

A modular batten and seam type photovoltaic roofing system comprising:

• I) a plurality of photovoltaic panels, each panel including:
• a base member having a generally planar central portion at least partially bounded by two upturned flanges;
• a photovoltaic device disposed on said central portion, said device including a positive terminal and a negative terminal;
• a positive terminal region associated with said base member and including a first electrical conductor in electrical communication with the positive terminal of said photovoltaic device;
• a negative terminal region associated with said base member and including a second electrical conductor in electrical communication with the negative terminal of said photovoltaic device;
• a first electrical connector affixed to said positive terminal region, in electrical communication with said first electrical conductor;
• a second electrical conductor affixed to said negative terminal region, in electrical communication with said second electrical conductor;
• said roofing system further including:
• II) a coupling member having a first end reversibly attachable to one of said electrical connectors on a first one of said plurality of panels and a second end reversibly attachable to one of said electrical connectors on a second one of said panels, said coupling member being operable to establish electrical communication between said first and second panels;
• III) a plurality of batten members, each configured to cover one upturned flange of each of two of said plurality of panels, when said two panels are adjacently disposed on a roof.
