Identifying Circuits in PV Systems

For PV systems, the circuit(s) between modules and from modules to the common connection point(s), of the direct-current system is known as the _____.

a) photovoltaic source circuit
b) photovoltaic array circuit
c) photovoltaic input circuit
d) photovoltaic output circuit

See answer and applicable Code reference

The correct answer is: a) photovoltaic source circuit

The provisions of Art. 690 apply to photovoltaic electrical energy systems. As noted in the definitions section of this Article (690.2), a photovoltaic source circuit is defined as "circuits between modules and from modules to the common connection point(s) of the DC system."
