Large Area Steady State Solar Simulator - Apollo

Transcription

1 AllReal APOLLO series steady-state solar simulator are AAA class which is the highest class on the world. AllReal APOLLO solar simulators designed with specific optical technology by tandem Xenon lamps, the uniformity can be assured within 2%. Every lamp module will be with stable uniformity and spectral characteristics without spending much time to adjust it. AllReal APOLLO solar simulator can also complete the illumination measurement in a short time by opening and closing the lamp cover, especially the spectral match and uniformity still keep stable (A class), it can be said that AllReal APOLLO solar simulator is the one that most similar to the real sun. The spectral coverage of AllReal APOLLO solar simulator is from 350nm to 3000nm, almost all of the thin film solar module (mono-si / poly-si / a-si / tandem Si / CIGS / CdS / DSSC) test can be completed by APOLLO. Moreover, the correct power voltage can also be gotten without reference cell. APOLLO have successfully built more than 100 lamp modules over the world, and have been verified to be the only one that keep AAA performance after long-term use. Therefore, APOLLO is the best choice for testing laboratory and quality inspection of company to select solar simulator. 1

4 AllReal APOLLO solar simulator features: A. AAA steady-state light source is the only one identified equal to the light from real sun. No matter what thin film photovoltaic module or photovoltaic module that need to expose to long-term illumination, it can obtain correct power voltage without derivation, approximation or compensation, truly conforms to testing requirements. B. Multi lamp module tandem design can assure AAA class even when any one of the lamp modules shot down.

The object under test needs to be at least 7.5 meters from and the light source, the reflection from the object does not interference optical characteristics, and the real Nature condition can be completely simulated. = Graph 2:Example from APOLLO in Intertek Shanghai Graph 1:Tandem design 4

Specific optical design, the irradiance uniformity can be assured AAA for long, and there s no need any iron grids or mask between lamp module and object under test, and the real Nature condition can be completely simulated. E. The measured value of APOLLO spectral mismatch is from , almost 5 times better than class A ( ).(Graph 5) 3.00 Apollo spectra vs. AM1.5G AM1.5G Apollo Wavelength (nm) Graph 5:APOLLO(Spectral Match):Better than Class A (defined by IEC ) 5

6 F. Smart automation design Operators can easily switch different illumination (200 W/m 2 ~1000 W/m 2 ) through touch screen, it can also keep AAA performance without any manual adjustment. (Table 3~7 Compliance with IEC Non-Uniformity of Irradiance Class A) Table 3 Table 4 Table 5 6

G. AllReal APOLLO solar simulators can integrate IV curve measurement system to provide complete photovoltaic solar module power voltage test solution. APOLLO can complete IV curve measurement under five different irradiances in an hour. (200 W/m 2 400W/m W/m W/m W/m 2 ) H. AllReal originally design and develop, manufactured in Taiwan, for sale in China, with guarantee after sale. 7
