Photovoltaic roofing wiring array, photovoltaic roofing wiring systems and roofs using them

A photovoltaic roofing wiring array for use with a plurality of photovoltaic roofing elements, each photovoltaic roofing element having a positive lead terminated in a positive connector and a negative lead terminated in a negative connector, and a lead-to-lead distance between the positive connector and the negative connector, the photovoltaic roofing wiring array comprising:

• a positive parallel wiring run, the positive parallel wiring run comprising a main line and one or more connection branches pendant from the main line, each connection branch being terminated in a positive connector;
• a negative parallel wiring run, the negative parallel wiring run comprising a main line and one or more connection branches pendant from the main line, each connection branch being terminated in a negative connector;
• and
• a plurality of series wiring runs, each series wiring run comprising a sequence of a plurality of wiring elements including a first wiring element and a last wiring element and optionally one or more interior wiring elements, each wiring element having a positive end terminated in a positive connector coupleable to the positive connector of the photovoltaic roofing elements, and a negative end terminated in a negative connector coupleable to the negative connector of the photovoltaic roofing elements, the series wiring elements being disposed sequentially in a substantially head-to-tail fashion from a positive connector of the positive parallel wiring run to a negative connector of the negative parallel wiring run, wherein
• the negative connector of the first wiring element in the sequence is disposed within one lead-to-lead distance of the positive connector of the positive parallel wiring run;
• the positive connector of the last wiring element in the sequence is disposed within one lead-to-lead distance of the negative connector of the negative parallel wiring run;
• and
• for any optional interior wiring elements in the sequence, the positive connector is within one lead-to-lead distance of the negative connector of the subsequent wiring element;
• and the negative connector is within one lead-to-lead distance of the positive connector of the previous wiring element,
• wherein each positive connector is coupleable to the positive connectors of the photovoltaic roofing elements;
• and
• each negative connector is coupleable to the negative connectors of the photovoltaic roofing elements,
• but wherein the positive parallel wiring run, the negative parallel wiring run, and the one or more series wiring runs are not coupled to any photovoltaic roofing elements;
• and
• wherein the positive parallel wiring run, the negative parallel wiring run, and the wiring elements of the series wiring run are physically interconnected such that the wiring array is provided as a single physically interconnected unit, in which
• adjacent wiring elements of each series wiring run are physically affixed, but not electrically interconnected, to one another,
• the first wiring element of the series wiring run is physically affixed, but not electrically interconnected, to the positive parallel wiring run, and
• the last wiring element of the series wiring run is physically affixed, but not electrically interconnected, to the negative parallel wiring run.
