Abstract

A system includes a photovoltaic module having photovoltaic cells, each having a width, and a roofing shingle having an exposure zone and a headlap zone. A plurality of slots extends from the exposure zone to the headlap zone and define tooth portions. A first one of the tooth portions has a first side defined by a first slot and a second side defined by a second slot adjacent to the first slot. The first tooth portion has a first width that is the photovoltaic cell width multiplied by a first positive integer. A second tooth portion has a first side defined by a third slot and a second side defined by a fourth slot adjacent to the third slot. The second tooth portion has a second width that is the photovoltaic cell width multiplied by a second positive integer different than the first positive integer.

 wherein the second width is the photovoltaic cell width multiplied by a first positive integer that is greater than 1,

wherein a third one of the plurality of tooth portions has a third width,

wherein the third width is the photovoltaic cell width multiplied by a second positive integer that is greater than 1 and different than the first positive integer,

wherein each of the roofing shingles does not include a photovoltaic cell.

2. The roofing system of claim 1 , wherein the plurality of roofing shingles comprises at least a first roofing shingle, wherein the first roofing shingle comprises thermoplastic olefin, polyvinyl chloride, or asphalt.

3. The roofing system of claim 2 , wherein a top surface of the first roofing shingle comprises embedded granules.

4. The roofing system of claim 1 , wherein the plurality of roofing shingle comprises at least a first roofing shingle and a second roofing shingle, wherein an arrangement of tooth portions of the second roofing shingle is not identical to an arrangement of tooth portions of the first roofing shingle.

5. The roofing system of claim 1 , wherein the plurality of roofing shingle comprises at least a first roofing shingle and a second roofing shingle, wherein an arrangement of tooth portions of the second roofing shingle is identical to an arrangement of tooth portions of the first roofing shingle.

6. The roofing system of claim 1 , wherein each of the first and second positive integers is selected from the group consisting of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

7. The roofing system of claim 1 , wherein the plurality of tooth portions of at least some of the plurality of roofing shingles comprises a fourth one of the plurality of tooth portions having a fourth width, wherein the fourth width is the photovoltaic cell width multiplied by 0.5.

8. A roofing system, comprising:

a plurality of photovoltaic modules on a roof deck,

wherein each of the plurality of photovoltaic modules includes a plurality of photovoltaic cells,
