Disclosed herein are photovoltaic building materials and related methods of manufacturing and installing such materials. In one embodiment, a modular roofing structure comprises a photovoltaic shingle panel having a planar lower surface and an upper surface, and a rigid back member having a length the same as or greater than the length of the shingle panel and attached to the planar lower surface of the shingle panel. The roofing structure also includes at least one electrical contact pad on a lower surface of the back member, and at least one electrical conductor electrically coupled to the shingle panel via the lower surface and passing through the back member and out the lower surface. In such embodiments, the electrical conductor is electrically coupled to the at least one contact pad and extends past a front end of the back member sufficient to electrically contact a contact pad on another back member of a separate modular roofing structure couplable to the first.

A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member comprises a step in thickness along a cross-sectional plane perpendicular to the substantially planar lower surface and parallel to the longitudinal axis of the rigid back member, wherein the overall thickness of the rigid back member at a highest level of the step is greater than the thickness of the front or back end of the rigid back member. 3. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 2, wherein the rigid back member comprises a trapezoid-shaped base and a plurality of walls extending from the base, the walls having a step in height in a cross-sectional plane that is perpendicular to the base and parallel to the longitudinal axis of the rigid back member, the step in height of the walls providing the step in thickness of the rigid back member. 4. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 3, wherein the plurality of walls includes first and second sets of walls disposed on opposite sides of and perpendicular to the longitudinal center axis of the rigid back member. 5. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 4, wherein each wall in the first set of walls and a corresponding wall in the second set of walls are offset from each other about the longitudinal axis of the rigid back member by an amount greater than the width of each wall. 6. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 2, wherein the step is configured to receive a front end of a second modular roofing structure that is substantially identical to the hip, ridge, or rake modular roofing structure. 7. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member comprises channels having openings formed therein communicating between a side of the rigid back member and an area near the longitudinal center axis of the shingle panel, whereby when the modular roofing structure is installed on a ridge vent roof, the channels allow ventilation of the roof to the outside environment. 8. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 7, wherein the channels are arranged in a zig-zag or herringbone pattern. 9. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 7, wherein the rigid back member comprises a trapezoid-shaped base having longitudinal edges and a plurality of walls extending from the base, the plurality of walls forming the channels. 10. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 9, wherein the rigid back member includes a plurality of pins extending from the longitudinal edges of the base. 11. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member includes a planar upper surface that is attached to the substantially planar lower surface of the shingle panel, a first lower surface inclined with respect to the upper surface, and a second lower surface adjacent to the first lower surface and parallel to the upper surface; and wherein the step in thickness of the rigid back member is formed at the juncture of the first lower surface and the second lower surface. 12. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member includes corrugations on the surface to be attached to the substantially planar lower surface of the shingle panel. 13. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member includes a slit along a portion of its longitudinal center axis for facilitating folding the rigid back member. 14. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the rigid back member is composed of a material selected from the group consisting of molded recycled tire rubber, plastic, metal, and wood. 15. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 14, wherein the rigid back member is composed of an injection-molded thermoplastic material. 16. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 15, wherein the thermoplastic material is selected from the group consisting essentially of polystyrene, polypropylene, polyethylene, ethylene-vinyl-acetate (EVA), ethylene-mythylene-acrylate (EMAC), neoprene, and polychlorosulfonated polymer (Hypalon). 17. A photovoltaic hip, ridge, or rake modular roofing structure according to claim 1, wherein the modular roofing structure comprises a plurality of rigid back members formed together end-to-end, each of the plurality having a corresponding photovoltaic shingle panel electrically connected to an adjacent panel on the modular roofing structure, wherein a rigid back member at a front end of the modular roofing structure comprises opposing electrical conductors electrically coupled to its photovoltaic shingle panel via the lower surface and passing through the front end back member and out its lower surface, the electrical conductors extending past a front of the front end back member sufficient to electrically contact corresponding opposing electrical contact pads located on another rigid back member couplable to the front end of the modular roofing structure. 18.
