Blog Report: Solar Panel Washing Practical Exam
Date: 22 October 2026
Today, our institution conducted a practical examination (50 marks) and a theory examination (70 marks) on solar panel washing and performance measurement.
Practical Examination (50 Marks)
- Inspected solar panels before washing.
- Recorded voltage, current, and power readings.
- Cleaned the panels to remove dust and dirt.
- Recorded readings after washing.
- Compared before-and-after readings.
Theory Examination (70 Marks)
The theory exam covered solar energy, solar panel working principles, system components, cleaning methods, safety precautions, and maintenance.
Before and After Washing
Before washing
Dust and dirt on panels.
After washing

| Reading | Before | After |
|---|---|---|
| Voltage (V) | Actual reading | Actual reading |
| Current (A) | Actual reading | Actual reading |
| Power (W) | Actual reading | Actual reading |
Conclusion
The examinations improved our theoretical knowledge and practical skills. Solar panel washing helps remove dust and may improve electricity generation. Actual readings depend on sunlight and temperature.
