NABCEP PV ASSOCIATE EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE
2025/2026
Voltmeter (and how to use?) - Answers A device used to measure voltage, or electrical potential
energy difference.
To use: turn the voltmeter to a higher setting than the maximum expected voltage. Touch the
black to negative and the red to positive.
Ohmmeter - Answers A device used to measure resistance. Multimeters can function as
ohmmeters.
Apparent Power - Answers In AC transmission, the measure of Volts times Amperes:
Voltamperes (VA).
Current at which body's muscles contract? - Answers 10 Milliamperes (aA)
STC, PTC, NOCT, and CEC - Answers STC - 1000 w/m^2, 25 degree module temp, 1.5
atmospheres
PTC - 1000 w/m^2, 20 degree ambient temp, 1.5 atmospheres, 1 m/s wind speed (this results in
a module temp of about 50 degrees)
NOCT - 800 w/m^2, 20 degrees ambient, 1 m/s wind speed
CEC - Same as PTC
Voltage Drop (what does length/diameter of cable do to voltage drop?) - Answers A decrease in
voltage along a conductor through which current is flowing. As the length of the cable increases,
so does its resistance. To decrease voltage drop in a circuit, you can increase the diameter of
the conductors.
NEC - Answers National Electric Code. It is a federal regulation, but enforcement is typically at
the local level.
diversion load - Answers An auxiliary load that is not a critical system load, but is always
available to utilize the full array power in a useful way to protect a battery from overcharge.
NRTL - Answers National Recognized Testing Laboratory
Maximum voltage on storage batteries for dwellings? - Answers Storage batteries for dwellings
shall have the cells connected so as to operate at less than 100 volts.
DSIRE - Answers Database of state incentives for renewables
IREC - Answers Interstate REC Standard Foudation
DC to dc converter - Answers Convert dc current from one voltage to another. An optimizer is a
