Engaged by SunPower, and in conjunction with SunBrush, CPS National looked at the condition of PV solar panels prior to, and after cleaning.

The range of testing took place on-site with the panels insitu, and included:

  • Electroluminescence (EL) tests
  • I-V curve tracing against Standard Test Condition (STC)
  • Gloss meter reflectance test

EL testing inspects the panels for physical damage that cannot be seen by the naked eye, with the post result showing no damage. After cleaning, both the I-V curve trace and gloss meter reading showed improved results.
