Abstract
Some embodiments of the present disclosure relate to an integrated photovoltaic (PV) roofing shingle comprising a photovoltaic (PV) module and a roofing shingle. In some embodiments, the roofing shingle is bonded to the PV module. In some embodiments, a bond strength between the roofing shingle and the PV module is from 5 N/mm to 60 N/mm tested according to ASTM D1876. In some embodiments, the integrated PV roofing shingle has a mass per unit area of 0.5 lb per square foot to 5 lbs per square foot. Methods, systems, and kits including the integrated PV roofing shingle are also disclosed.

1-8. (canceled)
A system, comprising:
- a plurality of integrated photovoltaic (PV) roofing shingles installed on a roof deck, wherein each of the plurality of PV roofing shingles comprises:
- a PV module;
- wherein the PV module comprises:
- a superstrate having a bottom surface and a top surface opposite the bottom surface;
- a first layer having a bottom surface and a top surface opposite the bottom surface, and
- a substrate having a bottom surface and a top surface opposite the top surface,
- wherein the bottom surface of the superstrate is above the top surface of the first layer,
- wherein the bottom surface of the first layer is above the top surface of the substrate,
- wherein each of the superstrate and the substrate comprises at least one material from the group consisting of a thermoplastic polyolefin, ethylene tetrafluoroethylene, polyolefin encapsulant, ethylene vinyl acetate encapsulant, and acrylics;
- and
- a roofing layer comprising a top surface and a bottom surface opposite the top surface,
- wherein the roofing layer comprises thermoplastic polyolefin (TPO),
- wherein the top surface of the roofing layer includes is a continuous flat surface,
- wherein the continuous flat surface of the roofing layer is juxtaposed with the bottom surface of the substrate of the PV module.
