6.90.1 General

6.90.1.1 Scope.

This article applies to solar PV systems, other than those covered by Article 6.91, including the array circuit(s), inverter(s), and controller(s) for such systems. [See Figure 6.90.1.l(A) and Figure 6.90.1.l(B).] The systems covered by this article may be interactive with other electrical power production sources or stand-alone or both, and may or may not be connected to energy storage systems such as batteries. These PV systems may have ac or de output for utilization.

FPN: Article 6.91 covers the installation of large-scale PV electric supply stations.

Alternating-Current (ac) Module (Alternating-Current Photovoltaic Module).

A complete, enYironmentally protected unit consisting of solar cells, optics, inYerter, and other components, exclusive of tracker. designed to generate ac power when exposed to sunlight.

Array.

A mechanically integrated assembly of module(s) or panel(s) with a support structure and foundation, tracker, and other components, as required, to form a de or ac power-producing unit.

Bipolar Photovoltaic Array.

A dc PV array that has nvo outputs, each having opposite polarity to a common reference point or center tap.
