polykristallijne module als 1 na beste getest tijdens de TÜV Rheinland’s 2010 Energy Yield test. De Yingli module presteerde 1,4% boven het gemiddelde
en slechts 0,3 % minder dan de beste uit de test, Schott Solar's Perform Poly 225 module. Yingli Green Energy’s multicrystalline PV module has come through TÜV Rheinland’s 2010 Energy Yield Test with flying colours, ranking second amongst the thirteen modules tested. First place in the testing went to Schott Solar's Perform Poly 225 module.
The Yingli module generated an energy yield 1.4% above the average level and just 0.3% less than the highest-ranked performer. TÜV’s year-long test measured the energy yield of modules under actual sunlight – as opposed to simulators – from 11 manufacturers in Europe, North America and Asia. Testing took place at the testing body’s Cologne site and finished on April 30.
"For the period of one year, the energy outputs of 13 different PV modules from 11 participating companies were measured. The data was then normalized to 1Wp of the TÜV Rheinland measured STC power and compared with one another," said Christian Bauerdick, project manager of the TÜV’s Energy Yield test. "The results can give an idea about the performance under real conditions for moderate climates like in Cologne, Germany."
