Performance and Efficiency Analysis
All expertise
Performance verification
We analyse measurement data and operating records to support the assessment of performance.
The EPC contractor commits to how much the plant will produce. We look at the plant's past production, calculate with software how much it should have produced, and compare the two. Where there is a gap, the cause often lies in the modules: solar panel degradation, solar panel defects such as cracks, potential induced degradation (PID) or a hot spot on a solar panel. The result gives solar asset management a technical basis for its decisions.
How we work
We verify the production performance of your operating plant through measurement and analysis.
Starting from the commitment
We take the EPC contractor's production commitment for the plant as the starting point of the assessment.
Past production
We review the plant's measured past production and its operating records, with their coverage and quality.
Calculating expected production
We calculate with software how much the plant should produce.
Comparison and conclusion
We compare measured and expected production, assess the performance through the solar performance ratio (PR) and report the results.
What we deliver
Our deliverables are set by the scope of each job; we do not hand over the same report package on every project.
Data coverage and quality
We state the period, completeness and gaps of the production data and operating records we reviewed.
The assessment method
We explain the method and the conditions against which we assessed performance.
The calculations
We show the calculation of expected production with the data and assumptions we used.
Conclusions
We report the gap between measured and expected production and the performance ratio (PR).

Our expert in this area
In performance verification we compare what the plant produced with what it should have produced. The assessment is useful when we can show from measurements where the gap comes from.
