Sample NABCEP - North American Board of Certified Energy Practitioners Practice Questions

Try these questions from our free NABCEP - North American Board of Certified Energy Practitioners practice tests. The correct answer and an explanation follow each question.

  1. Which SRCC (Solar Rating and Certification Corporation) rating is used to compare solar water heating collectors?

    • A. OG-100 Collector Rating
    • B. OG-300 System Rating
    • C. ISO 9001 certification
    • D. ASHRAE 90.1 compliance

Answer: A. OG-100 Collector Rating

SRCC OG-100 is the collector-level rating that measures thermal performance under standardized conditions, allowing consumers and installers to compare different collector models.

  • What does an insulation resistance test (megohm test) during commissioning detect?

    • A. Inverter efficiency
    • B. Ground faults or damaged insulation in wiring
    • C. Module power output degradation
    • D. Battery state of charge
  • Answer: B. Ground faults or damaged insulation in wiring

    A megohm test applies high voltage to conductors to detect insulation breakdowns or ground faults that could cause safety hazards.

  • What sizing tool does SRCC and the solar industry use to estimate annual solar water heating system performance by location?

    • A. ASHRAE load calculator
    • B. F-Chart method or Solar Rating and Certification Corporation OG-300 simulation
    • C. Manual J residential load calculation
    • D. RETScreen energy analysis
  • Answer: B. F-Chart method or Solar Rating and Certification Corporation OG-300 simulation

    The F-Chart method is the industry standard analytical tool for estimating the annual solar fraction and performance of solar water heating systems using local climate data.

  • What is the Solar Fraction (SF) of a solar thermal system?

    • A. The angle of the collector relative to true south
    • B. The percentage of the total heating load supplied by solar energy
    • C. The ratio of collector area to storage volume
    • D. The system's thermal efficiency at standard test conditions
  • Answer: B. The percentage of the total heating load supplied by solar energy

    Solar fraction represents the portion of a building's total water or space heating load that is met by the solar thermal system, with higher values indicating greater solar contribution.
