QuickSun® 130E

Compact cell and minimodule tester

High-performance cell and mini-module flash tester for R&D and quality control

Module components, such as silver paste, ribbons, and coatings need to be tested in a PV module to determine their influence in real-world conditions. The use of small modules for these tests adds convenience and space savings for laboratories. Some changes to module components might have only a small effect on overall power output, so accurate test results are key in observing the small changes.

QuickSun 130E is a compact mini-module flasher for testing of small PV modules. The Class A+A+A+ solar simulator can be equipped with a high resolution EL inspection as a single table top system.

  • I-V measurement and EL inspection within seconds with minimal module handling
  • The most cost-effective solution for small modules with state-of-the-art inspection tools
  • Class A+A+A+ solar simulator with continuous 300–1200 nm Xenon spectrum
  • Minimal footprint of 64 cm x 70 cm x 135 cm

Solar simulation

QuickSun 130E achieves A+A+A+ classification. Irradiance non-uniformity of < 1% is maintained over the test area of 30 cm by 30 cm. The spectrum produced by the Endeas Xenon flash extends from 300 to 1200nm, fully compatible with the new IEC 60904-9 Ed.3. The spectral coverage of the spectrum is 100% making sure variation in PV module materials does not go unnoticed.

Long-term instability (LTI) is typically < 0.5 % during the 60 ms long flash pulse – even the high efficiency and capacitance IBC and HJT modules can be measured accurately by applying the Capacitance Compensation (CAC) method. This scientifically justified procedure enables the measurement of the steady-state I-V curve in only 60 ms, eliminating the need for longer flash pulses.


High-quality EL images are acquired within seconds by a static camera setup. The EL image is captured after I-V measurement without any additional work required by the operator. Automatic defect analysis can be used to detect faults in the mini-modules.
