NABCEP Regulatory Compliance & Industry Standards 4 — Questions and Answers
Question 1: According to NABCEP's continuing education requirements, how many hours of continuing education must a PV Installation Professional complete per 3-year recertification cycle?
- 15 hours
- 30 hours (Correct answer)
- 45 hours
- 60 hours
Correct answer: 30 hours
NABCEP requires 30 hours of continuing education within each 3-year certification maintenance cycle for PV Installation Professionals.
Question 2: Which NEC article covers the installation of solar photovoltaic systems specifically?
- Article 480
- Article 625
- Article 690 (Correct answer)
- Article 705
Correct answer: Article 690
NEC Article 690 is dedicated to Solar Photovoltaic (PV) Systems and covers conductors, overcurrent protection, disconnects, grounding, and system output circuits.
Question 3: What does the 'Authority Having Jurisdiction' (AHJ) have the authority to do regarding PV installations?
- Set utility interconnection rates
- Approve, reject, or modify electrical inspection standards (Correct answer)
- Issue NABCEP certifications
- Override NEC requirements to be more permissive at their discretion
Correct answer: Approve, reject, or modify electrical inspection standards
The AHJ has the authority to approve or reject installations and may adopt local amendments to the NEC, including making requirements more stringent.
Question 4: A solar installer discovers that a rooftop PV system they are inspecting has module-level power electronics (MLPEs) that do not comply with rapid shutdown requirements. Who is ultimately responsible for bringing the system into compliance?
- The original installer
- The current system owner (Correct answer)
- The utility
- The AHJ
Correct answer: The current system owner
The system owner bears ultimate responsibility for code compliance; while the installer may have liability, the owner must ensure the installed system meets current requirements.
Question 5: California's Title 24 Building Energy Efficiency Standards require newly constructed low-rise residential buildings to have what solar-related feature?
- Battery storage systems
- Solar thermal water heating
- Solar-ready conduit and electrical panel space
- Minimum 3 kW PV systems (Correct answer)
Correct answer: Minimum 3 kW PV systems
California's 2020 Title 24 update requires most newly constructed low-rise residential buildings to include a minimum-sized photovoltaic system.
Question 6: Under OSHA's Hazard Communication Standard (HazCom), what document must be available to workers who handle batteries in solar+storage systems?
- Equipment warranty card
- Safety Data Sheet (SDS) (Correct answer)
- UL listing certificate
- NRTL test report
Correct answer: Safety Data Sheet (SDS)
OSHA's HazCom Standard (29 CFR 1910.1200) requires Safety Data Sheets (formerly MSDS) to be accessible to workers handling hazardous chemicals, including battery electrolytes.
Question 7: Which standard provides requirements for the design qualification and type approval of crystalline silicon PV modules?
- IEC 61215 (Correct answer)
- IEC 62109
- UL 1703
- ASTM E1036
Correct answer: IEC 61215
IEC 61215 specifies requirements for design qualification and type approval of crystalline silicon terrestrial PV modules for long-term operation.
