Together with WAVELABS, Germany’s national metrology institute is advancing photovoltaic metrology to meet the demands of the latest generation of high-performance solar modules. With its upgraded calibration system, Physikalisch-Technische Bundesanstalt (PTB) sets the gold standard for solar energy calibration. Watch our interview with Dr. Stefan Riechelmann, to gain first-hand insights.

World-Leading Calibration:

  • PTB achieves a measurement uncertainty of only 0.9% with WAVELABS’ flasher SINUS-3000 ADVANCED—most likely the world’s lowest uncertainty ever achieved.
  • Exceptional light field uniformity and ultra-stable drift rates guarantee consistent, long-term accuracy, with deviations of less than 0.2% sustained over nearly a year.

Driving Solar Innovation for a Greener Future:

  • With precise measurements and cutting-edge technology, PTB reduces risks for solar investments, optimizes module performance tracking, and paves the way for a more sustainable energy transition.
  • WAVELABS SINUS-3000 ADVANCED Solar Simulator features precise LED spectral control, ideal for next-gen technologies like perovskite/silicon tandem modules.
  • WAVELABS employs the proprietary technology of the SINUS-3000 ADVANCED in all of its products. Best-in-class precision and accuracy for fabs and labs.
