What determines the efficiency of a solar collector?

The efficiency of a solar collector depends on the ability to absorb heat and the reluctance to “lose it” once absorbed. Figure 7.1.1 illustrates the principles of energy flows in a solar collector. Fig. 7.1.1. Principle of energy flows in a solar collector . Temperature of the ambient air.

What is the principle of energy flows in a solar collector?

Principle of energy flows in a solar collector . Temperature of the ambient air. The efficiency parameters of a wide range of collectors can be found at This website list only collectors which have been tested according to the standard EN12975 by an impartial test institute.

What is the total solar irradiation?

Total solar irradiation is 1000 W/m2 on the collector plane. It is seen that in this example the ETC is best at high collector temperatures, the FPC with convection barrier is good at medium to high temperatures and that the FPC without convection barrier is good at low temperatures.

What is a technical guide – solar thermal systems?

“Technical guide – Solar thermal systems”, Viessmann GmbH, 2009. industry guidelines to which utilities can refer when considering/realizing SDH plants.

What are examples of collector efficiency based on aperture area?

Examples of collector efficiency based on aperture area as function of temperature difference between collector fluid and ambient air. Total solar irradiation is 1000 W/m2 on the collector plane.
