In order to generate key knowledge on CPV technology, ISFOC has already installed 1,4MW of CPV and is executing
3MW of power plants incorporating seven different technologies which will be finished in 2009. The objective of these
pilot plants is to assist the industries in the setting up of pilot production lines and to obtain very valuable information
such as reliability, suitability and production.
In collaboration with the various suppliers, ISFOC has followed in detail all the qualification tests and their results.
Therefore a great body of knowledge and experience is being built up.
After the completion of the plants, ISFOC has started the campaign of measurements, following its own methodology. It
is based on the equations of the Shockley model and only one measurement is needed to establish the nominal power of
the CPV system. Heat-sink temperature to calculate the cell temperature through the thermal resistance, DNI with a
pyrheliometer and the I-V Curve are measured in this procedure. But, ISFOC will also test other rating procedures, like
the ASTM 2527-E or the IEC draft for CPV modules. The results will be shown in this paper.
