Question 1

The following dc portion of a PV schematic (functionally grounded conductor not shown) is submitted to the building official for permit approval. The building official, who also is he AHJ, allow the system to be installed by requiring what NEC-required MINIMUM size equipment grounding conductor at Location A?

A : #12 aluminum

B : #10 copper

C : #8 copper

D : #6 aluminum

Answer: B

Question 2

Which of the following is an NEC requirement regarding access for large-scale PV electric power production facilities?

A : Field-applied hazard markings must be installed, and access to the supply station is to be restricted by fencing or other adequate means.

B : All fencing and associated gates must have ac and dc current and voltage exposure labvels and must be electrically isolated from the solar facility.

C : Arc flash warning labels must be field-applied by the installer at all access points for qualified persons and at the point of the utility interconnection directory.

D : Access to remote isolating equipment for servicing is allowed for individual other than qualified persons when the equipment is enclosed within a secure structure.

Answer: A

Question 3

A PV system installation utilizes micro inverters connected to each module of the array. Each micro inverter has a nominal rated output of 250WV. Single phase. The microinverters are listed so that multiple inverters may be connected in parallel to a single feeder circuit, and each inverter has ancable and connector rated for 30A. What is the MAXIMUM number of inverters that may be wired together on a single 30A feeder circuit?

A : 15

B : 17

C : 23

D : 28

Answer: C

Question 4

A homeowner is weighing the PV module options for a roof-mounted solar array. Which is a correct option to present to the homeowner?

A : Building-integrated PV shingles will be flush or nearly flush with other shingles, but the electrical energy produced will be less than polycrystalline or monocrystalline modules.

B : Rapid shutdown requirements within 1 ft of the array boundary.

C : Polycrystalline modulesare more shade-tolerance than eitheramorphous or monocrystalline modules and allow a larger array to be installed, including in area where shading could be seasonally problematic.

D : Microinverters can be installed with either polycrystalline or monocrystalline modules, negating the need for rapid shutdown compliance.

Answer: D

Question 5
