State-of-the-art testing for PV module performance

Accurate determination of photovoltaic (PV) module performance requires precise measurement of a module’s electrical characteristics to identify defects early in the development stages before they make it into the field. Our state-of-the-art PV testing laboratories provide product services for performance verification across a range of climates and conditions.

Testing services for development, pre-production and production stages include:

  • PV module nameplate verification
  • PAN file verification
  • IAM coefficients
  • Potential Induced Degradation (PID)
  • Light and Elevated Temperature-induced Degradation (LeTID)
  • Dynamic Mechanical Loading
  • Salt Mist and Corrosion
  • Dust and abrasion
  • Accelerated Life Testing including:
    • Temperature cycling
    • Damp Heat exposure
    • UV exposure
    • Hot-freeze cycling

Durability and reliability

A PV module's ability to endure environmental stressors and maintain operation and continue to do so over time is paramount to achieving financial models for built PV systems. Often required by lenders and referred to as qualification testing UL provides a full suite of testing to assess stakeholder risk.
