Sample Punjab PSEB Sr. Sec. NSQF Electronics (Solar Panel Installation Technician) Practice Questions

Try these sample questions to review concepts for the Punjab PSEB Sr. Sec. NSQF Electronics (Solar Panel Installation Technician) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The photovoltaic (PV) effect converts sunlight into electricity primarily by:
A.Generating a potential difference when photons free charge carriers in a semiconductor junction
B.Heating water to drive a steam turbine
C.Spinning a magnet inside copper coils with wind
D.Burning hydrogen produced from solar heat
Explanation: In a PV cell, absorbed photons create electron–hole pairs at a p–n junction and the built-in field separates charges, producing DC voltage and current under load.
2A solar PV module produces which form of electrical output under normal sunlight?
A.Alternating current (AC) at grid frequency
B.Direct current (DC)
C.Three-phase AC only
D.High-frequency radio-frequency energy only
Explanation: PV cells and modules generate DC. An inverter is needed when AC is required for household loads or grid connection.
3STC (Standard Test Conditions) for rating PV modules typically include irradiance of:
A.100 W/m², 50 °C cell temperature
B.500 W/m², 40 °C cell temperature
C.1000 W/m², 25 °C cell temperature, AM 1.5 spectrum
D.2000 W/m², 0 °C cell temperature
Explanation: Module nameplate ratings (Wp, Vmp, Imp, etc.) are referenced to STC: 1000 W/m² irradiance, 25 °C cell temperature, and AM 1.5 spectrum.
4A 400 Wp module operating for 5 peak sun hours (PSH) under ideal conditions can produce about how much energy in that day?
A.80 Wh
B.400 Wh
C.5000 Wh
D.2000 Wh (2 kWh)
Explanation: Approximate daily energy ≈ Wp × peak sun hours = 400 W × 5 h = 2000 Wh = 2 kWh (before system losses).
5As crystalline silicon cell temperature rises above 25 °C, module voltage and power typically:
A.Voltage falls and maximum power usually decreases
B.Both increase strongly
C.Remain exactly constant at STC values
D.Become zero above 30 °C
Explanation: Silicon cells have a negative voltage temperature coefficient. Hot cells reduce Voc/Vmp and usually lower power despite small current changes.
6Irradiance of 1000 W/m² means that on each square metre of surface:
A.1000 joules of heat are stored permanently
B.1000 watts of solar power are incident
C.1000 amperes flow automatically
D.1000 volts appear across any metal plate
Explanation: Irradiance is power per unit area (W/m²). 1000 W/m² is the STC reference full-sun intensity used in module ratings.
7A PV array delivers 20 A at 48 V into a load. Instantaneous power is:
A.2.4 W
B.68 W
C.960 W
D.9600 W
Explanation: Electrical power P = V × I = 48 V × 20 A = 960 W.
8Compared with diffuse light on a cloudy day, direct beam irradiance on a clear day typically allows a PV array to:
A.Produce only AC without an inverter
B.Charge only at night
C.Operate solely on infrared heating of the frame
D.Produce significantly higher power near its rated capability
Explanation: Clear-sky direct irradiance is much higher than heavy cloud diffuse light, so array current and power rise toward nameplate capability (temperature and angle still matter).
9A typical crystalline silicon PV module is built from:
A.Series-connected solar cells laminated behind tempered glass with a weather-sealed backsheet or glass
B.A single large electromagnet and copper rotor
C.Only loose bare wafers without encapsulation
D.A diesel injector and fuel rail
Explanation: Commercial modules interconnect many cells in series (and sometimes parallel groups), encapsulate them, and protect them with glass, frame, and backsheet/glass for outdoor service.
10On a module nameplate, Voc means:
A.Voltage under continuous overload only
B.Open-circuit voltage with no load connected
C.Operating current at maximum power
D.Total array watt-peak only
Explanation: Voc is the open-circuit voltage measured with no load (and usually at STC on the label). It is higher than Vmp, the voltage at maximum power.

Punjab PSEB Sr. Sec. NSQF Electronics (Solar Panel Installation Technician): Suggested Study Strategy

1Pair every MCQ category with school practical demonstrations — theory recall without supervised skill practice is incomplete for NSQF Electronics.
2Learn module nameplate parameters first (Wp, Voc, Isc, Vmp, Imp) — many series/parallel and testing questions start there.
3Draw simple stand-alone and grid-tied block diagrams from memory: modules → controller/inverter → battery/load/grid with isolation and earthing points.
4Practise series vs parallel mentally with small numbers (e.g., two 20 V / 5 A modules) before tackling shading mismatch questions.
5Never invent government subsidy rupee figures for cost-economics answers — learn qualitative factors (capital cost, O&M, energy yield, payback concept) from official materials.
6Do not neglect practical and INA marks — they are 60 of 100 under the official Theory 40 + Practical 50 + INA 10 scheme.
7Keep this bank distinct from Matric home-appliance Electronics revision: focus on solar PV installation language, not electric iron/fan service.

Frequently Asked Questions
