What is Instantaneous Collection Efficiency?

Instantaneous collection efficiency is the measure of a solar collector's effectiveness in converting solar energy into useful thermal energy at a specific moment. It is calculated as the ratio of the useful heat gain to the solar radiation incident on the collector's surface at that instant. This efficiency depends on factors like solar intensity, ambient temperature, and heat loss from the collector.
