Maximum Power determination for PV module manufacturers

Getting it right every time

PV module manufacturers are facing challenges

Manufacturers want to squeeze every watt out of a module. Repeatable measurements of the true Pmax are critical to make this happen. New technologies require solar simulators with high accuracy to fully yield the energy potential of a module.
  • The price pressure limits the maximum allowable OPEX and CAPEX
  • Fast process adaption is required for new PV module technologies
  • Need for control of the entire measurement system (calibration module, procedures, training, environment, simulator, samples)
  • When high reproducibility is not achieved there is no data correlation between production lines and plants
  • Low repeatability can result in discussions with EPC on module data
  • If measurement uncertainty is high, can cause 2% loss of value down the value chain

  • 1982

    • The worldwide PV module production exceeds 21 MW. Spire develops a tower flasher (SPI-SUN 240) to test c-Si modules
  • 1995

    • Spire moves to tabletop solar simulators for better uniformity and usability (SPI-SUN 460i). The worldwide PV production reaches 1 GW and the market is dominated by c-Si modules.
  • 2015

    • Annual PV module production exceeds 60GW, high efficiency technologies like PERC gain market share, and bifacial, half-cut, shingled cells are introduced. Spire flashers are developed to test these technologies (5100SLP).
  • 2020

    • PERC/PERT/Topcon cells are dominant and PV manufacturers move to larger wafers. Spire flashers are upgraded to test larger modules up to 2.6 m x 1.4 m.
