AAA+ High Performance Light Soaker

Study performance and degradation of different PV technologies over time with our temperature-controlled A class steady-state solar simulator.

With the HPLS, RnD and certification labs can perform:

  • Accurate Power determination of all PV module types and technologies
  • Stabilization and LeTID tests
  • Accurate temperature coefficient measurements
  • Energy rating testing

Eternalsun Spire has developed a High-Performance AAA+ Light Soaker (HPLS) with extremely accurate temperature control and in-situ IV characterization. The system combines AAA+ class steady state illumination (IEC60904-9 ed. 3 ready) and extremely accurate and uniform temperature control from -10 to 95 C, allowing in-situ IV measurements. It can measure the metastability of thin film modules such as CIGS, CdTe, GaAs; IV measurements of OPV, Perovskite and tandem cells, perform temperature coefficient measurement and test of cell coupons. Temperature stability is ± 1°C, which is the main contributor to the improved accuracy of measurement, and can be integrated with humidity control.
