Sample C&G 2922-34 Solar PV Practice Questions

Try these sample questions to test your C&G 2922-34 Solar PV exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a solar cell, what physical process converts sunlight directly into electrical energy?

A.The photoelectric heating of water

B.The photovoltaic effect

C.Electromagnetic induction

D.Thermionic emission

Explanation: A solar cell generates electricity through the photovoltaic effect: photons of light free charge carriers in a semiconductor p-n junction, producing a direct current. This is distinct from heat-based or induction-based generation.

2Solar irradiance at a site is normally expressed in which units?

A.Watts per square metre (W/m2)

B.Kilowatt-hours (kWh)

C.Amperes (A)

D.Lumens (lm)

Explanation: Irradiance is the instantaneous power of solar radiation falling on a surface, measured in watts per square metre (W/m2). Standard Test Conditions use 1000 W/m2.

3PV modules are rated at Standard Test Conditions (STC). Which set of values defines STC?

A.800 W/m2, 20 C cell temperature, AM1.0

B.1000 W/m2, 25 C cell temperature, AM1.5

C.1000 W/m2, 45 C cell temperature, AM1.0

D.1200 W/m2, 25 C cell temperature, AM2.0

Explanation: Standard Test Conditions are 1000 W/m2 irradiance, a cell temperature of 25 C and an air mass of AM1.5. Module peak power (Wp) is quoted at STC so products can be compared fairly.

4On a module I-V curve, which point represents the condition where the module delivers its greatest power output?

A.The open-circuit voltage (Voc)

B.The short-circuit current (Isc)

C.The maximum power point (MPP)

D.The point where current equals zero

Explanation: The maximum power point (MPP) is the combination of voltage (Vmp) and current (Imp) that yields the highest power on the I-V curve. Inverters use maximum power point tracking (MPPT) to hold the array near this point.

5What happens to a crystalline silicon module's open-circuit voltage (Voc) as the cell temperature falls below 25 C?

A.Voc decreases

B.Voc increases

C.Voc stays exactly the same

D.Voc drops to zero

Explanation: Crystalline silicon modules have a negative temperature coefficient for voltage, so as the cell gets colder than STC the Voc rises. This is why the maximum system DC voltage must be calculated using the lowest expected cell temperature.

6Three identical 12 V, 8 A PV modules are connected in series. What is the approximate output voltage and current of the string?

A.12 V at 24 A

B.36 V at 8 A

C.36 V at 24 A

D.12 V at 8 A

Explanation: Connecting modules in series adds their voltages while the current stays the same. Three 12 V modules give 36 V, and the current remains 8 A. This is the basis of building a string to reach a usable DC voltage.

7Two PV strings, each producing 30 V at 9 A, are connected in parallel. What is the combined output?

A.60 V at 9 A

B.30 V at 18 A

C.60 V at 18 A

D.30 V at 9 A

Explanation: Connecting strings in parallel adds their currents while the voltage stays the same. Two 9 A strings give 18 A, and the voltage remains 30 V. Parallel grouping increases array current.

8A roof has space for 10 PV modules each rated at 410 Wp. What is the nominal peak power (array rating) of the installation?

A.41 kWp

B.4.1 kWp

C.410 kWp

D.0.41 kWp

Explanation: Array peak power is the sum of the module peak powers: 10 x 410 Wp = 4100 Wp = 4.1 kWp. This nominal rating is used for design, DNO notification and yield estimates.

9What does the term 'peak power' or Wp of a PV module describe?

A.Its output at any time of day

B.Its rated DC power output at Standard Test Conditions

C.The maximum AC power its inverter can deliver

D.Its output on the shortest day of the year

Explanation: Peak power (watt-peak, Wp) is the module's rated DC power output measured at Standard Test Conditions of 1000 W/m2 and 25 C. Real output varies with actual irradiance and temperature.

10Why is the current produced by a PV array described as direct current (DC) rather than alternating current (AC)?

A.Because it reverses direction 50 times per second

B.Because it flows in one direction only

C.Because it is always above 230 V

D.Because it cannot be measured with a meter

Explanation: PV cells produce direct current, which flows in one constant direction. An inverter is required to convert this DC into 230 V 50 Hz AC that is compatible with the grid and household loads.

C&G 2922-34 Solar PV Study Tips from Top Performers

1Make sure your 18th Edition knowledge is current, especially BS 7671 Section 712 for solar PV, because the test assumes you already understand general electrical installation requirements.

2Practise the core PV calculations: modules in series add voltage while current stays the same, modules in parallel add current while voltage stays the same, and array power is roughly module power times the number of modules.

3Learn the G98 and G99 split cold: G98 applies up to and including 16 A per phase (about 3.68 kW single phase) with notification within 28 days, while G99 applies above that and needs DNO approval before connection.

4Because the knowledge test is open book, tab your BS 7671 and IET Code of Practice so you can find isolation, earthing, labelling and SPD requirements quickly.

5Understand why module voltage rises in cold conditions, since maximum Voc at the lowest expected temperature drives DC cable, isolator and inverter voltage ratings.

6Revise the commissioning and test sequence from the IET Code of Practice and IEC 62446-1, including insulation resistance, polarity, string open-circuit voltage and short-circuit current checks, and what goes in the handover documentation.
