Schott Solar’s Poly 225 PV modules received top honors after TÜV Rheinland completed its 2010 energy yield testing. The Schott module beat out 12 other competitors in a test that used real energy yield instead of climatic chamber tests and power measurements with a sun simulator. The test was carried out for a full year under real solar radiation conditions, with Schott’s Poly 225 placing first.
“Thanks to new software, a completely shadow-free test roof and, last but not least, highly precise measuring equipment, we were able to raise the 2010 energy yield test to an entirely new standard,” said Christian Bauerdick from TÜV Rheinland. “For one full year, we measured the energy output of PV modules and compared them with one another.”
The testing consisted of TÜV Rheinland continually keeping the individual modules at their maximum power point (MPP) by using electrical charges. The organization used only values at which all test modules were MPP and decided its top result by the yield per watt peak. The complete measurement system consisted of a central compilation of meteorological data, module temperature measurements and global solar radiation at the level of the test subjects and MPP tracking and output measurement.
Schott Solar will be exhibiting at Intersolar Europe in Booths A1.560 and A1.480.
