Location-independent and accurate performance analysis of solar modules, performed with our mobile PV-Lab
With the help of characteristic curve (I/U), electroluminescence, infrared and HighPot measurements, hidden defects are made visible – reliably, quickly and precisely. This allows weak points and risks to be uncovered before modules fail or safety is compromised.
I/U Characteristic curve measurement
By measuring the current-voltage characteristic, the power of the modules is determined under standard test conditions and at different irradiance levels. In addition, irregularities in the characteristic curve are detected.
- Full-Spectrum-Long-Pulse LED Flasher
- Spectrum: Class A+ according to IEC 60904 Ed2
- Illumination instability: < +/- 0.25 % class A+ according to IEC 60904 Ed2
- Local inhomogeneity: < +/- 2 % class A according to IEC 60904 Ed2
- Power measurement: better +/- 3 % possible
- Irradiance: 200 – 1200 W/m²
HighPot-test
High voltage testing can detect insulation and grounding faults that can easily become a safety hazard.
- Connection and diode test
- Test of continuity of grounding according to IEC 61730-2 / MST 13
- Test current up to 30 A, resistance measurement between all four frame parts
- Insulation test according to IEC 61730-2 / MST 16
- Test voltage up to 6 kV, test for currents < 50 μA
- Insulation resistance test under wetting according to IEC 61730-2 / MST 17 (optional)
