Our capabilities

Advanced testing solutions, on your site

Two diagnostics that together tell you what a module is really producing — and what is quietly failing inside it.

IV Curve Test
I (A)V (V)

Performance, measured in the field

Full current–voltage characterisation of installed modules and strings under real irradiance, corrected to STC.

  • IEC 60891:2021 compliant methodology
  • Accurate performance evaluation
  • Detects power loss & module mismatch
  • Detailed IV report with insights
Electroluminescence Test
Electroluminescence scan of a PV module

See the cracks before they cost you

High resolution EL imaging reveals micro cracks, cell fractures and interconnect defects invisible to the eye.

  • Detects micro cracks & hidden defects
  • Ensures long term reliability
  • High resolution EL imaging
  • Comprehensive EL report

Is your solar plant making as much electricity as it should?

Mark your project on the map and enter a few details. We'll show how much electricity it should make, what in your area could be lowering it, and whether a test is worth it.

Why output could be lower at this location

Other common reasons for low output
  • Inverter switching off: power cuts, high grid voltage or overheating make it stop during sunny hours.Check the inverter's fault log first
  • A failed string, fuse or connector: a whole row of panels stops contributing without any visible sign.Found by: IV curve test
  • Cracked or damaged panels: from hail, rough handling or people walking on them; often invisible.Found by: EL imaging
  • Hot spots and failed bypass diodes: from shade, dirt or manufacturing defects.Found by: IV curve test + EL imaging
  • Faster-than-normal ageing: yellowing, peeling or PID can steal 1–3% more each year than the warranty allows.Found by: IV curve test + EL imaging
  • Smaller system than on paper: fewer or lower-wattage panels than invoiced.Found by: IV curve test

    These are estimates. Output can also drop because of dust, shade, inverter faults or power cuts. Only a field test (IV curve or EL) can confirm the real condition of your panels.
