Collector Efficiency - an overview | ScienceDirect Topics
The solar collector efficiency represents the ratio between the heat absorbed by the solar receiver Q ˙ r and the incident solar radiation I T0, normal on the collector’s aperture of area A a. Thus the thermal efficiency of the solar collector is η coll = Q ˙ r / I T 0 A a. The solar collector can be divided in two subsystems.
