1What is the FIRST step a solar worker should take before performing any maintenance on a PV system?

A.Put on safety glasses and gloves

B.De-energize the system and follow lockout/tagout (LOTO) procedures

C.Check the weather forecast for the day

D.Notify the utility company of the planned maintenance

Explanation: Lockout/tagout (LOTO) procedures must be followed before any work on electrical systems to prevent accidental energization. This is the critical first safety step to protect workers from electrical shock or arc flash. While PPE is important, de-energizing the system takes priority. Exam tip: LOTO is always the first action in any maintenance scenario question.

2Which type of personal protective equipment (PPE) is MOST important when working on energized PV circuits?

A.Hard hat and steel-toed boots

B.Voltage-rated insulating gloves and safety glasses

C.Hearing protection and knee pads

D.High-visibility vest and sunscreen

Explanation: When working on energized PV circuits, voltage-rated insulating gloves protect against electrical shock, and safety glasses protect against arc flash. These are the most critical PPE items for electrical work. While other PPE items may also be required on a job site, electrical protection is paramount when circuits are energized. Exam tip: Always match PPE to the specific hazard — electrical work requires electrical-rated PPE.

3Why can a PV module NOT be fully de-energized simply by turning off the inverter?

A.The inverter stores energy in its capacitors for several hours

B.PV modules produce DC voltage whenever exposed to light, regardless of inverter status

C.The utility grid continues to back-feed power through the modules

D.The battery backup system keeps the modules energized

Explanation: PV modules generate DC electricity whenever they are exposed to light — this is a fundamental property of the photovoltaic effect. Turning off the inverter disconnects the AC side but does not stop the modules from producing voltage. This is why PV systems present unique electrical hazards even when the system appears to be 'off.' Exam tip: Remember that sunlight = voltage on PV modules, always.

4What is the primary purpose of an equipment grounding conductor (EGC) in a PV system?

A.To carry the normal operating current from the modules to the inverter

B.To provide a low-impedance path for fault current to facilitate overcurrent device operation

C.To improve the power output efficiency of the PV array

D.To connect the PV system to the internet for monitoring

Explanation: The equipment grounding conductor provides a low-impedance path for fault current back to the source, allowing overcurrent protection devices (fuses or breakers) to clear the fault quickly. This protects people from electric shock and reduces fire risk. The EGC does not carry normal operating current. Exam tip: Grounding is about safety — providing a safe path for fault current, not normal current.

5According to OSHA fall protection standards, at what height above a lower level must fall protection be used during PV installation on a roof?

A.4 feet

B.6 feet

C.10 feet

D.15 feet

Explanation: OSHA requires fall protection for construction workers at heights of 6 feet or more above a lower level. This applies to PV installers working on rooftops. Fall protection can include guardrails, safety nets, or personal fall arrest systems. Exam tip: The 6-foot threshold for construction is a commonly tested OSHA standard — don't confuse it with the 4-foot general industry standard.

6What is the purpose of a rapid shutdown system on a PV installation?

A.To maximize power production during peak sun hours

B.To reduce voltage on conductors to safe levels for emergency responders

C.To automatically clean the PV modules during rain

D.To prevent the inverter from overheating during high ambient temperatures

Explanation: Rapid shutdown systems reduce voltage on PV conductors to safe levels (typically within 30 seconds) so that firefighters and other emergency responders can safely work on or near a building with a PV system. NEC 690.12 specifies rapid shutdown requirements. Exam tip: Rapid shutdown is a life-safety feature required by the NEC, primarily for first responder protection.

7Which of the following is an arc fault hazard specific to PV systems?

A.Water leaking into the electrical panel from rain

B.Loose or damaged DC connections between modules that create high-temperature arcing

C.Using an undersized AC branch circuit breaker

D.Plugging too many appliances into a single outlet

Explanation: Loose, corroded, or damaged DC connections in a PV string can create series arc faults, producing sustained high-temperature arcs that can ignite surrounding materials. PV systems are particularly susceptible because DC arcs do not self-extinguish at zero-crossing like AC arcs. This is why arc-fault circuit interrupters (AFCIs) are required on PV systems. Exam tip: DC arc faults are more dangerous than AC because DC arcs are sustained and don't self-extinguish.

8A PV installer notices a cracked module during installation. What should they do?

A.Install it anyway since the crack is cosmetic and won't affect performance

B.Apply silicone sealant to the crack and continue installation

C.Remove the module from the installation, tag it as damaged, and replace it

D.Rotate the module 180 degrees so the crack faces down

Explanation: A cracked PV module is a safety hazard — moisture can infiltrate through cracks, causing ground faults, arc faults, or shock hazards. Cracked modules should never be installed. They should be removed, clearly tagged as damaged, and replaced with an undamaged module. Exam tip: Any physical damage to a PV module is a safety concern, not just a performance issue.

9What type of fire extinguisher is appropriate for an electrical fire at a PV installation?

A.Class A — for ordinary combustibles like wood and paper

B.Class B — for flammable liquids like gasoline

C.Class C — rated for energized electrical equipment

D.Class D — for combustible metals

Explanation: Class C fire extinguishers are specifically rated for fires involving energized electrical equipment. Using water or a non-rated extinguisher on an electrical fire can cause electrocution. Since PV modules cannot be fully de-energized during daylight, a Class C extinguisher is essential at PV installations. Exam tip: Class C = electrical fires. Many ABC-rated extinguishers also cover Class C.

10What is the main reason PV systems require warning labels and placards at the point of utility connection?

A.To advertise the solar company that performed the installation

B.To inform utility workers and emergency responders of the presence of a second power source

C.To display the system's energy production for the homeowner

D.To comply with homeowner association aesthetic requirements

Explanation: Warning labels at the service entrance and utility meter inform utility workers and emergency responders that the building has a second source of power (the PV system) in addition to the utility grid. This is critical because even if utility power is disconnected, the PV system may still be producing electricity. Exam tip: Labels and placards are life-safety requirements under the NEC, not optional.
