Question:
Maximum efficiency is obtained in
Maximum efficiency is obtained in
Show Hint
Focus = Heat. The more you concentrate the light $(Dish > Tube > Flat Plate)$, the higher the efficiency potential.
Updated On: May 5, 2026
- Flat plate collector
- Paraboloid dish collector
- Evacuated tube collector
- Solar cooker
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Concentrating solar collectors achieve higher temperatures and efficiencies by focusing sunlight onto a smaller area.
Step 2: Meaning
Efficiency in solar collectors often depends on the concentration ratio.
Step 3: Analysis
A paraboloid dish tracks the sun in two axes and concentrates light to a single focal point, allowing for the highest concentration ratios and thermal efficiencies among the options.
Step 4: Conclusion
The paraboloid dish collector provides maximum efficiency.
Final Answer: (B)
