MODULE TESTING

Early identification of defective solar modules and measurement of module performance

Service description

Intact solar modules with maximum performance play a key role in assuring the yield of your PV system. Using high-precision measuring equipment and proven testing methods, our experts inspect your modules for weaknesses and determine their actual performance – on-site and in our in-house laboratory. As a result, defects are identified and rectified before a project is completed and you achieve the forecasted energy yield.


Services

Electroluminescence measurement 

  • Producing an electroluminescence image on-site or in-house laboratory
  • Identification of defects, e. g. micro-cracks, inactive cell sections, screen printing errors, cell contamination and crystallization defects

Low light characteristics
(only in connection with electroluminescence measurement)

  • Recording current-voltage characteristic curvesbelow various irradiance intensities
  • Determination of the maximum power points as well as other relevant operating points
  • Assessment of current-voltage characteristic curve profiles
  • Test report including with the curve profile for efficiency characteristics

Thermal analysis

  • Measurement of individual or all moduless for thermal irregularities using a thermal imaging camera
  • Identification of thermal irregularities such as defective cell strings, hot junction boxes and hot spots
  • Summary report including a list of affected modules with serial numbers and recommendations as to how to proceed further

Thermal analysis by helicopter

  • Measurement of all modules for thermal irregularities from a helicopter using a thermal imaging camera
  • Summary report

Your benefits

  • Assurance of forecasted energy yield through identification of defective solar modules
  • Risk mitigation by module tests following delivery and installation
  • Prevention of dismantling/transport damage due to on-site module measurement
  • Valid report to prove warranty claims to the manufacturer
