Chinese integrated photovoltaic product manufacturer, Yingli Green Energy Holding Company, has announced that its "Yingli Solar" brand modules have attained the "Power Controlled" certification from the Germany-based TUV Rheinland Group.
"Power Controlled" certification provides independent verification and assurance that the real rated power of Yingli Solar brand modules lies within the specified tolerance stated in the company's datasheets.
Liansheng Miao, the chairman and CEO of Yingli Green Energy said that they were pleased to be among the first companies to receive 'Power Controlled' certification. He added that with the "Power Controlled" certification they could offer their customers and investors an additional level of assurance that Yingli modules deliver the power promised, and by reducing the uncertainty in PV system performance they were helping lay the foundation for grid-parity PV solutions in the future.
TUV Rheinland "Power Controlled" certification includes periodic third-party assessment of Yingli Green Energy's pulsed solar simulators, measurement procedures, maintenance and calibration intervals and power output verification testing of PV modules through random sampling and evaluation of flash-test data from the production line. The measurement procedures and calibration are traceable to the standards of World PV Scale.
