NABCEP Exam Questions with all Correct & 100%
Verified Answers |Already Graded A+
STC Watts can be calculated by ✔Correct Answer-Vmp x Imp = STC watts
Sealed Lead Acid Batteries maintenance ✔Correct Answer-Cleaning terminals
wind uplift forces in construction industry is measured in ✔Correct Answer-pounds per square inch
direction on a compass is ✔Correct Answer-azimuth
voltage is ✔Correct Answer-pressure
what is specified on a charge controller? ✔Correct Answer-maximum voltage
units for irrandiance ✔Correct Answer-power per area
what is used to calculate maximum system voltage? ✔Correct Answer-temperature
what is reflected light called? ✔Correct Answer-Albedo
transformers convert ✔Correct Answer-high voltage low current to low voltage high current
undersized PV array ✔Correct Answer-decreases battery life
STC ✔Correct Answer-Standard Test Condition, 25C 77F, 1.5 air mass, 1000w/m^2
PTC ✔Correct Answer-113F, 45C wind speed 2.2 mph (1m/s)
voltage with no current is the difference of electrical potential between two terminals of a device
when disconnected from any circuit. There is no external load connected. No external electric
current flows between the terminals. ✔Correct Answer-Voc
is current flowing freely from a photovoltaic cell through an external circuit that has no load or
resistance; the maximum current possible. It is the current through the solar cell when the voltage
across the solar cell is zero ✔Correct Answer-ISC when the solar cell is short circuited
concentrated PV only works with ✔Correct Answer-direct sunlight, generates electricity from the
sunlight
electromagnetic field radiation ✔Correct Answer-EMF
NEMA 3 and NEMA 3R ✔Correct Answer-National Electrical Manufacturers Association, if the
disconnect is outside the house it should be rated 3R
transformerless ✔Correct Answer-means it is ungrounded
higher elevation and less atmosphere ✔Correct Answer-higher irradiance and more current
