Which of the following provides highest energy conversion efficiency in non-concentrating solar collectors?
A. Flat plate collectors
B. Evacuated flat plate collectors
C. Evacuated-tube collectors
D. Parabolic collectors
Answer:B
Which of the following provides highest energy conversion efficiency in non-concentrating solar collectors?
A. Flat plate collectors B. Evacuated flat plate collectors C. Evacuated-tube collectors D. Parabolic collectors
Explanation: Evacuated flat plate collectors provide the highest energy conversion efficiency in non-concentrating solar collectors. Parabolic collector is not a non-concentrating collector.
