Question 1
Consider the following concerns in order. Which answer associates each one with its most
direct topic?
1. Mounting PV modules securely, torqueing fasteners to manufacturer specifications, and
managing module-level electronics (optimizers, microinverters)
2. Complying with rapid shutdown requirements and fire code pathways
3. Establishing electrical safety procedures, including Lockout/Tagout (LOTO) and arc flash
safety awareness
A. 1: 1 Safety and Site Preparation; 2: 2 Mechanical and Structural Installation; 3: 3 Mechanical
and Structural Design
B. 1: 2 Mechanical and Structural Installation; 2: 1 Safety and Site Preparation; 3: 3 Mechanical
and Structural Design
C. 1: 3 Mechanical and Structural Design; 2: 2 Mechanical and Structural Installation; 3: 1 Safety
and Site Preparation
D. 1: 2 Mechanical and Structural Installation; 2: 3 Mechanical and Structural Design; 3: 1 Safety
and Site Preparation
Correct Answer: D
Full Explanation: The correct associations are 1 with 2 Mechanical and Structural Installation
(Mounting PV modules securely, torqueing fasteners to manufacturer specifications, and
managing module-level electronics (optimizers, microinverters)); 2 with 3 Mechanical and
Structural Design (Complying with rapid shutdown requirements and fire code pathways); 3 with 1
Safety and Site Preparation (Establishing electrical safety procedures, including Lockout/Tagout
(LOTO) and arc flash safety awareness). Exchanging these topics changes the subject of one or
more concerns rather than preserving their distinct meanings.
Question 2
A task combines 1 Reviewing Customer Expectations and Project Feasibility with 1 Performance
Monitoring and Troubleshooting, but the current discussion only considers Reviewing site
characteristics, geographic location, and environmental conditions. Which concern would
supply the missing focus?
A. Interpreting production data and performance indices from remote monitoring platforms
B. Checking monitoring system data communication, sensor pairing, and portal connectivity
C. Setting up fall protection systems (guardrails, personal fall arrest systems, warning lines) for
elevated and roof work
D. Evaluating utility rate structures, net metering policies, and interconnection rules
Correct Answer: A
Full Explanation: The existing discussion concerns 1 Reviewing Customer Expectations and
Project Feasibility, specifically Reviewing site characteristics, geographic location, and
environmental conditions. To add the second focus, 1 Performance Monitoring and
Troubleshooting, the relevant material is Interpreting production data and performance indices
from remote monitoring platforms. Adding more material from the first topic would not address
the missing second concern.

Procedures (Conducting open-circuit voltage (Voc) and short-circuit current (Isc) tests on strings); 2
with Calculating photovoltaic module electrical parameters (Choosing appropriate raceways,
conduit sizing, junction boxes, and combiner boxes); 3 with 1 Performance Monitoring and
Troubleshooting (Interpreting production data and performance indices from remote monitoring
platforms). Exchanging these topics changes the subject of one or more concerns rather than
preserving their distinct meanings.
Question 4
Several different issues need to be distinguished. Which answer identifies their topics in the
order shown?
1. Identifying electrical service panel capacities, main breaker ratings, and interconnection
points
2. Performing visual checks of electrical terminations and polarity before energizing

than preserving their distinct meanings.
Question 6
Both 3 System Turn-On and Functional Testing and 2 Electrical Testing and Verification
Procedures need attention. Work has so far concentrated on Checking monitoring system data
communication, sensor pairing, and portal connectivity. Which topic-specific addition is still
needed?
A. Evaluating structural integrity of existing buildings (roofs, framing, foundations)
B. Testing arc-fault circuit interruption (AFCI) functionality where applicable
C. Sizing overcurrent protection devices (fuses, circuit breakers) for DC and AC circuits
D. Verifying grid synchronization, voltage, frequency, and export limitation controls (if applicable)
Correct Answer: B
