Building Source Circuits and Configuring Modules

PV arrays are comprised of source circuits (from one to dozens or hundreds, depending upon the desired

power). Source circuits are comprised of PV modules connected in series. The number of modules in a

source circuit can vary depending on the module voltage, ambient temperature range, and desired

system voltage, provided the max system voltage does not exceed that allowed by NEC Section 690-7

(600 volts).

When calculating the system operation voltage use the module Vp. However, when calculation the max

system voltage for the NEC compliance, use Voc.

When determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls

connected to PV output, use the values of Isc and Voc marked on the module or found in the module

Spec Sheet.

NOTE

Under certain normal conditions, a photovoltaic module is likely to experience conditions that produce

more current and/or voltage than reported at standard test conditions. Accordingly, the values of Isc and

Voc marked on this module should be multiplied by a factor of 1.25 (see Section 690-8 of the National
