CFV has excellent outdoor testing capabilities. We have fixed racks, single and two-axis trackers. The irradiance in New Mexico is among the highest in the US, with an average of about 6.5 kWh/m2 per day on the fixed rack. This allows CFV to accumulate high irradiance doses quickly to evaluate energy yields, light induced degradation (LID) behavior or conduct energy rating and performance measurements outdoors. Specifically for difficult to measure modules, such as thin-film (CdTe, CIGS, a-Si) and CPV (concentrator modules), this outdoor evaluation capacity provides better performance ratings than indoor measurements which require spectral corrections or just cannot be done properly. CFV often uses outdoor performance measurements to verify indoor measurements and to calibrate the indoor flasher. CFV works closely with NREL, Sandia National Laboratories and Fraunhofer ISE in round robin studies and has a quality assurance contract in place with Fraunhofer ISE, ensuring the best possible measurement accuracy and consistent results. In addition, we use the highest quality reference cell from the German PTB, which has the lowest uncertainty available anywhere in the world.
For yield and LID studies we can utilize Fraunhofer’s continuous curve tracers to obtain performance data over extended periods and evaluate module performance at different environmental conditions and over time.
