🎓 Academic Journey Progression Map
✓ Why This Topic Works (Student & Parent Reassurance)
Why this topic works for +2 Science: Aligns with NEB Grade 12 Physics thermodynamics and current electricity chapters, requiring accessible lab multimeters and a small 12V PV module.
1. Introduction & Problem Statement
Overview: Grade 11/12 Physics investigatory project measuring output voltage, current, and maximum power curve of a small solar PV panel at varying operating temperatures.
Background Context (Nepal): +2 Science students under NEB must complete annual investigatory projects in Physics, Chemistry, and Biology. Solar energy efficiency under Nepal's varying mountain temperatures offers a solid experimental setup.
2. Research Objectives
- ›Set up 10W solar PV panel connected to variable resistor load and digital multimeters
- ›Measure open-circuit voltage (Voc) and short-circuit current (Isc) at temperatures from 15°C to 50°C
- ›Calculate panel power output and fill factor across temperature points
- ›Plot V-I characteristic curves and temperature coefficient of voltage
3. Proposed Methodology
- Mount 10W solar panel under controlled halogen heating lamp or natural outdoor sunlight
- Use infrared thermometer or digital sensor attached to panel backboard to log surface temperature
- Vary temperature using controlled cooling fan or lamp distance
- Record voltage and current readings using digital multimeters across 5 temperature steps
- Plot P-T graphs and compute the negative temperature coefficient of power (%/°C)
$ Worked Example / Sample Scenario
Sample Scenario: A Class 12 student in Chitwan measures PV output as temperature rises from 22°C to 48°C, proving a 0.41%/°C power drop and presenting detailed V-I graphs for NEB practical evaluation.
