Question # 1

A PV system is designed with a 48V battery bank and a 5 kW inverter. The load requires 20 kWh/day, and the system must have 2 days of autonomy with a maximum depth of discharge (DoD) of 50%. What is the minimum battery capacity required in Ah?

417 Ah

833 Ah

1000 Ah

1667 Ah

Question # 2

A homeowner is concerned that a 6kWdc PV system might be experiencing a performance issue. The homeowner has noticed what appears to be declining production. The installer analyzes the following data acquisition system (DAS) results for each year since the installation:

Given the data, which is the MOST likely conclusion to draw?

The system has experienced above-average degradation and a module warranty claim should be explored.

A combination of normal module degradation combined with cloudy weather has caused lower output in the past few years.

There is a problem with the DAS because the peak sun hours do not correlate with production values and the das should be repaired.

There is an intermittent inverter failure that is causing production to be lower than expected and the inverter should be repaired.

Question # 3

A PV array with 58 in. X 38 in modules in portrait orientation is to be mounted at a 35 tiit angle on a shingle roof that has a 5:12 pitch. Assuming the support leg is attached to the top of the modules and is perpendicular to its face, what is the length of the support leg for the modules?

12.73 in.

18.25 in.

24.24 in.

40.50 in.

Question # 4

When performing a system checkout after completing the installation, what is the SAFEST sequence of tasks to detect installation errors before closing any disconnects to the inverter, charge controller, or batteries?

Perform visual inspection, check polarity and measure open-circuit voltage.

Perform visual inspection, install source circuit fuses, and measure open-circuit voltage.

Perform visual inspection, install source circuit fuses, and measure open-circuit current.

Install source circuit fuses, verify that all equipment-grounding conductors are secure, and measure ac line voltage.

Question # 5

According to the NEC, if the PV system disconnect and the building service disconnect are at different locations, there MUST be a/an:

Interface that shuts down the PV system if the utility connection is lost.

Permanent plaque or directory that indicates the locations of both disconnects.

Means of locking out both disconnects when the PV system inverter is being serviced.

Permanent plaque or directory that indicates the location of the PV utility connection.

Question # 6

A racking system is designed for a wind speed of 120 mph. The site’s design wind speed increases to 130 mph. What is the percentage increase in wind pressure?

10%

17%

25%

33%

Question # 7

An installer is using ½ in lag boits to secure roof-monitoring hardware to rafters through a roof deck. Which of the following should the installer predrill?

A pilot hole one-half the length of the bolt

A pilot hole one-fourth the length of the bolt

A 1/8 in, pilot hole through the roof into the rafter

A 5/16 in pilot hole through the roof into the rafter

Question # 8

When doing initial inspections on a PV system that was installed using racking that is not compliant with UL.2703, an inspector should pay special attention to which electrical attribute?

The equipment grounding conductor must be irreversibly spliced.

Each PV module needs to be bonded to the equipment grounding conductor.

Racking needs to be bonded to a supplemental grounding electrode conductor.

The grounding conductor must be bonded directly to the primary grounding electrode.

Question # 9

During a site assessment, an installer identifies a 100-foot-tall tree 150 feet south of a proposed PV array. The site latitude is 40°N. Will this tree cause shading on December 21st between 9 AM and 3 PM solar time?

Yes, shading will occur all day

Yes, shading will occur before 10 AM only

No, shading will not occur

Insufficient data to determine
