PHOTOVOLTAIC ROOFING WIRING ARRAY, PHOTOVOLTAIC ROOFING WIRING SYSTEM AND ROOFS USING THEM

摘要

The present invention provides photovoltaic wiring arrays and photovoltaic wiring systems suitable for use in rooftop photovoltaic power generation systems. Accordingly, one aspect of the invention provides 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 system 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; and 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, wherein each positive connector is coupleable to the positive connectors of the photovoltaic roofing elements; and wherein each negative connector is coupleable to the negative connectors of the photovoltaic roofing elements. In some embodiments of the invention, the photovoltaic roofing wiring arrays are substantially prefabricated.
