Solar performance analysis services
sunalysis offers six independent analysis services for utility-scale PV plants, covering every stage from pre-COD capacity testing to repowering. Each one starts from the plant’s own SCADA, meter, and weather data and ends in a clear, defensible technical report.
The six services
- Pre-COD Capacity Testing: Independent verification of installed PV capacity and expected system performance.
- Underperformance Diagnostics: Root-cause analysis of production losses using plant data and modeling.
- Asset Performance Evaluation: Independent comparison of measured output against modeled expectations.
- Warranty Claim Support: Technical analysis supporting module, inverter, or EPC warranty claims.
- Curtailment Quantification: Analysis of curtailed generation events and their financial impacts.
- Repowering Analysis: Evaluation of inverter replacement and system upgrade scenarios.
