Solar roofing system

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,
• wherein each of the plurality of photovoltaic cells has one constant photovoltaic cell width;
• and
• a plurality of roofing shingles proximate to the plurality of photovoltaic modules on the roof deck,
• wherein each of at least some of the plurality of roofing shingles having
• a top surface,
• an exposure zone at a lower end of the top surface and
• a headlap zone at an upper end of the top surface, and
• a plurality of tooth portions extending from the lower end toward the headlap zone,
• wherein a first one of the plurality of tooth portions has a first width,
• wherein the first width is the photovoltaic cell width multiplied by a first positive integer that is greater than 1,
• wherein a second one of the plurality of tooth portions has a second width,
• wherein the second 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.

A method, comprising:

• obtaining a plurality of photovoltaic modules,
• wherein each of the plurality of photovoltaic modules includes a plurality of photovoltaic cells,
• wherein each of the plurality of photovoltaic cells has one constant photovoltaic cell width;
• and
• obtaining a plurality of roofing shingles,
• wherein each of at least some of the plurality of roofing shingles having
• a top surface,
• an exposure zone at a lower end of the top surface and
• a headlap zone at an upper end of the top surface, and
• a plurality of tooth portions from the lower end toward the headlap zone,
• wherein a first one of the plurality of tooth portions has a first width,
• wherein the first width is the photovoltaic cell width,
• wherein a second one of the plurality of tooth portions has a second width,
• 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 do not include a photovoltaic cell;
• and
• installing the plurality of photovotaic modules and the plurality of roofing shingles proximate one another above a roof deck.
