In utility-scale solar, every watt counts. Verifying that the PV modules delivered to your project site perform as promised is critical—not just for energy output, but for financing, risk mitigation, and long-term operational success. That’s where PV Module Batch Testing comes in.
What is PV Module Batch Testing?
PV Module Batch Testing is a rigorous process that evaluates the performance and reliability of photovoltaic (PV) modules before they’re installed in the field. GroundWork’s industry-leading testing suite includes:
- Batch Flash Testing: Verifies power output against nameplate ratings.
- PAN File Generation + IAM: Creates precise modeling data with Incident Angle Modifier (IAM) measurements.
- Reference Module Characterization: Delivers temperature-corrected, high-accuracy data using our proprietary Eclipse™ system.
- Reliability testing optimized for near-term degradation modes such as UVID, PID, LID, LETID, etc, that can impact commissioning.
This end-to-end service ensures that performance expectations are met, early-stage degradation risks are identified, and projects remain compliant with warranty and financing requirements.
Why is Batch Testing Important?
Batch testing offers several high-impact benefits:
- Verify the watts you paid for: Confirm actual power output and ARC coating effectiveness.
- Minimize performance risk: Identify issues like LID, LeTID, PID, and more before capacity testing.
- Meet investor and lender expectations: Align with key performance metrics during commissioning.
- Reduce uncertainty in performance models: Generate highly accurate PAN files with low-uncertainty inputs.
With testing timelines of just 2–3 months, GroundWork delivers results within typical construction schedules giving you confidence before modules go in the ground.
