Verified PV performance, at portfolio scale.
A reliable verification layer for solar energy data. Detect deviations faster, validate KPIs against clear assumptions, and generate proof-ready reports for stakeholders
Minimum persistent deviation identified relative to expected energy over defined observation windows.
Scalable verification applied across distributed assets and multi-site portfolios.
Photovoltaic systems evaluated through continuous performance verification.
Three pillars for reliable performance verification.
Measured reference
Performance verification starts from measured energy, not device telemetry.
Long-term comparison
Measured and expected production are compared over time to detect persistent deviation.
Structured evidence
Results are organized into reproducible metrics and reports.
KPIs for all the portfolio
All systems are evaluated using IEC 61724–aligned, model-based performance verification. Measured energy is compared against a validated expected model to quantify efficiency and deviations across the portfolio.
- Measured AC energy at point of interconnection as input to performance verification
- Independence from inverter vendor logic
Expected production modeling
Expected energy is calculated using irradiation data, system configuration, and degradation assumptions, providing a stable baseline for comparison.
- Weather-based expected production
- Explicit and reviewable assumptions
Deviation detection over time
The system evaluates how measured production deviates from expected values over time. Persistence is treated as signal, not noise.
- Deviation magnitude and duration
- Seasonality and degradation accounted for
From deviation to plausible causes
When measured energy deviates from the expected model, patterns are analyzed to identify plausible causes before inspection, reducing uncertainty and guiding interventions.
- Deviation patterns compatible with soiling, shading, environmental losses, or electrical/configuration faults
- Verification of intervention impact (e.g., post-cleaning recovery)
Automated performance reporting
The system generates structured reports that document ongoing performance verification over a defined period.
- Reports generated automatically on a fixed schedule
- Reports document verified performance and detected deviations
Infrastructure-light integration
Connect existing metering and certified data sources without hardware or field installation. Portfolio-wide performance verification from a single interface.
- No hardware dependency or on-site installation
- Vendor-agnostic integration across portfolios
Receives regular reports documenting whether the system is producing as expected.
Provides proactive maintenance through continuous performance verification and periodic reporting.
Uses consistent verification results to validate system behavior after installation or maintenance.
Relies on documented and reproducible outputs for independent verification.
