NEW QUESTION 22
A homeowner is weighing the PV module options for a roof-mounted solar array. Which is a correct option to present to the homeowner?

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.

Rapid shutdown requirements within 1 ft of the array boundary.

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.

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

All protected loads are connected in multiwire branch circuits.

The peak current from the sealed lead- acid batteries must not exceed peak demand currents.

The stand-alone system configuration can adequately supply current to all protected load branch circuit.

NEW QUESTION 29
A grid-connected PV system on a dwelling is producing 30% less power than expected. The conductors from threes strings of modules enter into a 3-pole fused dc disconnect, and each ungrounded conductor is connected to a separate pole. On the inverter side of the switch terminals, the three strings are combined. The dc disconnect switch is opened. The voltages on the array side of theswitchare 440 on string #1, 444V on string
#2, and 0V on string #3. The dc disconnect is then closed and the inverter resumes operating, still producing about 30% less power than expected. A clamp-on ammeter is used to measure the dc current of each string of each string of modules where they enter the rooftop junction box. The operating currents of each string are
3.9A for string #1, 3 85A for string #2, and 4.3 A for string #3. What is the MOST likely with the system?

Positive and negative output conductors of string #3 are faulted together.

String #3 has an open connection and is not contributing any voltage.

A ground fault is causing the current from strings #1 and #2 to flow into string #3.

There is lower module mismatch in string #3 than in string #1 and #2.
