Sample UPMSP High School Solar Repair Practice Questions

Try these sample questions to test your UPMSP High School Solar Repair exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What primary physical phenomenon is responsible for converting light directly into electricity in a solar PV cell?

A.Photovoltaic effect

B.Thermoelectric effect

C.Piezoelectric effect

D.Electrochemical oxidation

Explanation: The photovoltaic effect occurs when incident photons absorb enough energy to free electrons within a semiconductor material (such as silicon), creating electron-hole pairs that are separated by an internal P-N junction potential to generate direct current (DC).

2Which semiconductor material is most widely used in standard commercial solar PV panels?

A.Silicon

B.Germanium

C.Gallium arsenide

D.Copper indium gallium selenide

Explanation: Silicon is the dominant semiconductor material in commercial solar photovoltaics, accounting for over 90% of global PV panel production due to its abundance, stability, and suitable bandgap.

3What type of electrical current is directly produced by solar PV panels under sunlight?

A.Direct Current (DC)

B.Alternating Current (AC)

C.Pulsating AC

D.High-frequency AC

Explanation: Solar PV panels generate Direct Current (DC) because electrons flow continuously in one direction across the P-N junction when exposed to solar radiation.

4Under Standard Test Conditions (STC), what is the standard irradiance value used to rate solar panel wattage?

A.1000 W/m²

B.800 W/m²

C.500 W/m²

D.1200 W/m²

Explanation: Standard Test Conditions (STC) mandate an irradiance of 1000 W/m², a cell temperature of 25°C, and an Air Mass ratio of AM 1.5.

5What standard cell temperature is specified under Standard Test Conditions (STC)?

A.25°C

B.20°C

C.45°C

D.0°C

Explanation: Standard Test Conditions (STC) define cell temperature as exactly 25°C (77°F).

6When identical solar panels are connected in series, how do total system voltage and current change?

A.Voltage increases while current remains the same

B.Current increases while voltage remains the same

C.Both voltage and current increase proportionally

D.Both voltage and current decrease

Explanation: Connecting panels in series sums their individual voltages while keeping the total circuit current equal to that of a single panel.

7When identical solar panels are connected in parallel, how do total system voltage and current change?

A.Current increases while voltage remains the same

B.Voltage increases while current remains the same

C.Both voltage and current double regardless of panel count

D.Both voltage and current stay constant

Explanation: Connecting panels in parallel sums their individual output currents while maintaining the same terminal voltage as a single panel.

8What parameter is defined as the maximum voltage a solar panel produces when disconnected from any load under bright sunlight?

A.Open-circuit voltage (Voc)

B.Maximum power voltage (Vmp)

C.Short-circuit current (Isc)

D.Nominal system voltage

Explanation: Open-circuit voltage (Voc) is the maximum voltage measurable across solar panel terminals when no current is flowing (zero load resistance).

9What parameter represents the maximum output current of a solar panel when its positive and negative terminals are shorted together?

A.Short-circuit current (Isc)

B.Maximum power current (Imp)

C.Open-circuit voltage (Voc)

D.Reverse leakage current

Explanation: Short-circuit current (Isc) is the maximum current drawn from a solar panel when the output terminals are shorted together at zero terminal voltage.

10What component inside a solar module junction box prevents reverse power flow and hot-spot damage during partial shading?

A.Bypass diode

B.Step-up transformer

C.AC circuit breaker

D.Smoothing capacitor

Explanation: Bypass diodes are wired across cell strings in the junction box to conduct current around shaded or damaged cells, preventing cell overheating (hot spots) and power loss across the remaining series string.

About the UPMSP High School Solar Repair Exam

The Uttar Pradesh UPMSP High School (Class 10) Solar-System Repair examination (subject code 979) is conducted by Uttar Pradesh Madhyamik Shiksha Parishad (UPMSP), Prayagraj. Official Board Syllabus pages on upmsp.edu.in list Class 9/10 PDFs for code 979. High School candidates offer six subjects under the published subject-combination rules. Common full-marks pattern is Theory 70 + Internal/Practical/Project 30 = 100 with approximately 3 hours 15 minutes for the theory paper. This exam covers photovoltaic principles, solar panel installation, inverter and battery maintenance, electrical wiring, and fault diagnostics. The 100 questions on this page are an English-language MCQ study adaptation for UPMSP Code 979 concept drills and self-assessment.

Assessment

Official UPMSP High School mixed written theory paper (objective and constructed-response items as per subject design) with common Theory 70 + Internal 30 = 100 full marks pattern for Class 10 vocational subjects, duration typically 3 hours 15 minutes. Local bank: English-language four-option MCQ study adaptation with explanations — not a full mixed-paper simulation or official-format substitute. Subject code 979.

Time Limit

3 hours 15 minutes (typical UPMSP High School theory paper; confirm current scheme for the subject)

Passing Score

Minimum 33% marks in the subject (commonly 33/100 combined theory + internal/practical as applicable); for theory+internal schemes, school sources often cite minimum 23/70 theory and 10/30 internal — confirm current UPMSP regulations/circulars.

Exam Fee

As per UPMSP High School examination fee notification for school (institutional) and private candidates for the current examination year on upmsp.edu.in / prereg.upmsp.edu.in — confirm the latest circular; subject papers are not separately priced on this page. Class 9/11 advance registration fee of INR 50 per student is a separate pre-registration charge, not the High School exam form fee. (Uttar Pradesh Madhyamik Shiksha Parishad (UPMSP))
