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.
