US Classification:

521733

Abstract:

The present invention is premised upon a through-roof connector assembly comprising one or more photovoltaic building sheathing elements capable of being affixed on a building structure, the photovoltaic building sheathing element including a sheathing element electrical connector along a sheathing element peripheral edge; a through-roof connector edge piece assembly that abuts a portion of the photovoltaic building sheathing element and includes: a body portion, an edge piece electrical connector, one or more wire leads that are connected on one end to the edge piece electrical connector; a wire guiding member with at least one conduit hole, the wire guiding member located under the through-roof connector edge piece assembly when assembled; and an under-roof junction device that is removably connected to the wire guiding member.

Abstract:

A solar array system includes a plurality of power-generator modules, each power-generator module having an identical form factor and comprising a plurality of photovoltaic cells wired for power generation. The system also includes at least one sensor module having a substantially identical appearance and form factor as the power-generator modules and comprising a like plurality of photovoltaic cells. The operational state of the system is monitored by an array performance monitor, which measures signals sent from the various modules. At least one photovoltaic cell in the sensor module delivers a short-circuit current signal to the array performance monitor and at least one photovoltaic cell in the sensor module delivers an open-circuit voltage signal to the array performance monitor. These signals are used to calculate a theoretical power output of the array system, which is compared to the actual power output.
