How This Automation Works
Scheduled Interval or Real-Time Data Feed → Performance Report with Anomaly Alerts
Data Collection and Normalization
System automatically retrieves string-level performance data from inverters, monitoring equipment, and data loggers. Simultaneously collects environmental data including irradiance, temperature, and weather conditions. Normalizes all data to common timestamps and units for accurate comparison.
Baseline Calculation and Comparison
Calculates expected performance for each string based on current environmental conditions, historical efficiency patterns, and manufacturer specifications. Compares actual output against these baselines to identify deviations and performance gaps across all strings.
Anomaly Detection and Classification
Applies statistical algorithms to identify outliers and performance anomalies. Classifies issues by severity (critical, warning, informational) and probable cause (shading, soiling, equipment failure, degradation). Filters false positives caused by transient conditions.
Impact Analysis and Prioritization
Calculates lost production for each underperforming string in kWh and revenue terms. Assesses cumulative impact on site performance. Prioritizes issues based on severity, financial impact, and trend direction to guide maintenance resource allocation.
Report Generation and Alert Distribution
Generates comprehensive performance reports with visual analytics, trend charts, and string comparison matrices. Creates prioritized alert notifications with diagnostic details and recommended actions. Distributes reports to operations teams via email, dashboard, or mobile notifications based on urgency.
How It Works
String-level performance monitoring is critical for maximizing solar array efficiency and preventing revenue loss. This automated analysis system continuously tracks voltage, current, and power output from each string, comparing actual performance against expected baselines to instantly flag degradation, shading issues, or equipment failures. The system aggregates data from inverters and monitoring equipment, performs statistical analysis to identify outliers, calculates performance ratios, and generates detailed reports with actionable insights. By automating string performance analysis, solar operators can detect issues before they escalate, prioritize maintenance activities based on impact, and ensure every string operates at peak efficiency. The system maintains historical performance data, tracks degradation trends over time, and provides predictive analytics to forecast maintenance needs, enabling proactive management of large-scale solar installations.
The Trigger
Initiates automatically at defined intervals (hourly, daily) or when new performance data is received from inverters, monitoring systems, or data loggers, ensuring continuous tracking of string-level metrics.
The Action
Generates comprehensive string performance analysis with comparative metrics, identifies underperforming strings with severity ratings, calculates lost production estimates, and sends prioritized alerts to maintenance teams with diagnostic recommendations.
Common Use Cases in Solar
- Utility-scale solar farms monitoring thousands of strings across multiple inverters to maintain optimal fleet performance and quickly identify equipment failures
- Commercial rooftop installations tracking string performance to ensure guaranteed energy production levels and meet power purchase agreement obligations
- Solar O&M providers managing portfolios of distributed sites, using automated analysis to prioritize field service activities across multiple locations
- Asset owners conducting performance verification during warranty periods to document underperformance and support manufacturer claims
- EPC contractors performing commissioning validation to ensure all strings meet specified performance criteria before project handover
- Energy management teams optimizing solar self-consumption by identifying production constraints and maximizing on-site generation capacity
