PV Performance Analyzer Sensor Measurements for Fault Diagnosis

Measurement Data of PV Performance Analyzer contains sensor measurements from a portable photovoltaic performance analyzer prototype. The data likely includes high-speed I–V/P–V curve traces, dual-path irradiance estimates, and diagnostic indicators from laboratory and outdoor tests on a crystalline-silicon module. The dataset was authored by Ambe Harrison and last updated on May 10, 2026.

Use Cases

• Validate PV module electrical accuracy based on high-speed I–V/P–V curve traces
• Compare irradiance estimation methods based on dual-path optical and electrical sensor data
• Diagnose PV degradation patterns such as shading and soiling based on parameter-deviation analysis and curve-shape indicators
• Benchmark low-cost sensor calibration against reference solar power meter data

Strengths

• Electrical accuracy reported as about ±1% for curve reconstruction
• Curve sweeps typically exceed 1000 points per sweep
• Data is licensed under CC-BY-4.0 for open use

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
