Yingli Green Energy announced at its annual global customer conference that its Yingli Solar brand modules have received the power controlled certification from TÜV Rheinland. The power controlled certification provides independent verification and assurance that the real rated power of Yingli Solar brand modules are within the specified tolerance stated in the company’s datasheets.
The certification is meant to reduce the risk and uncertainty in the real power installed in PV systems and can in turn decrease the financial risk for investors. The power controlled certification consists of periodic third-party assessments of Yingli’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.
“We are pleased to be among the first companies to receive ‘Power Controlled’ certification,” Mr. Liansheng Miao, chairman and CEO of Yingli, commented. “At Yingli Green Energy we are focused on continuously improving our product quality, and we strive to underpin our innovations with certifications from leading independent third parties. With the ‘Power Controlled’ certification we can offer our customers and investors an additional level of assurance that our modules deliver the power that we promise, and by reducing the uncertainty in PV system performance we are helping lay the foundation for grid-parity PV solutions in the future.”
