NV C-2G Photovoltaics Practice Questions - Nevada C-2G Photovoltaics Contractor Examination Exam - NV C-2G Photovoltaics Practice Questions - Nevada C-2G Photovoltaics Contractor Examination Exam

Question 1

A photovoltaic cell produces electricity primarily because photons absorbed in a semiconductor p-n junction:

Free electron-hole pairs that the built-in electric field separates into a usable current Heat the junction until thermoelectric voltage appears across the metal contacts Spin the module frame so magnetic flux cuts the interconnect ribbons Store charge chemically in the encapsulant the way a battery stores ions

Correct Answer:

Free electron-hole pairs that the built-in electric field separates into a usable current

Question 2

Standard Test Conditions (STC) used on a crystalline-silicon module nameplate are:

1000 W/m² irradiance, 25°C cell temperature, AM1.5 spectrum 800 W/m² irradiance, 20°C ambient, 1 m/s wind (NOCT) 1100 W/m² irradiance, 0°C cell temperature, AM0 space spectrum 1000 W/m² irradiance, 45°C cell temperature, AM1.0 spectrum

Correct Answer:

1000 W/m² irradiance, 25°C cell temperature, AM1.5 spectrum

Question 3

As crystalline-silicon cell temperature rises above 25°C while irradiance stays constant, the dominant electrical change is:

Open-circuit voltage falls and maximum power usually falls Open-circuit voltage rises sharply and fill factor increases Short-circuit current falls by about 0.4 percent per °C Maximum-power voltage is unaffected because MPPT holds Vmp fixed

Correct Answer:

Open-circuit voltage falls and maximum power usually falls

Question 4

Twelve identical modules are wired as two parallel strings of six modules in series. Compared with one module, the array’s nominal string voltage and combined current are:

Voltage about 6 times and current about 2 times Voltage about 12 times and current about 12 times Voltage about 2 times and current about 6 times Voltage unchanged and current about 12 times

Correct Answer:

Voltage about 6 times and current about 2 times

Question 5

If plane-of-array irradiance drops from 1000 W/m² to 500 W/m² at the same cell temperature, the most accurate statement is:

Isc falls by about half and Voc falls only a little Voc falls by about half and Isc stays nearly constant Both Voc and Isc fall by about half Both Voc and Isc stay at nameplate because voltage is fixed by the inverter

Correct Answer:

Isc falls by about half and Voc falls only a little
