Model Explainability — Which Fuzzy Rules Fired?

For today's prediction, see exactly which fuzzy rules (out of 62) had the strongest activation, what their IF-THEN logic looks like in plain English, and which weather features contributed most.

Suggestion: Cross-check with the other trained models (Tima, Jeddah, Al-Ahsa) using the multi-model comparison tab — predictions may diverge more than usual under these conditions.

Multi-Day Cloud Cover Heatmap

Hourly cloud cover (%) across daytime hours (6 AM – 7 PM). Darker blue = more cloud cover. Use this to plan maintenance windows and forecast generation dips.

ERA5 Cross-Model Comparison

Compares fuzzy system predictions against ERA5 reanalysis (another model, not ground-truth sensor data). Optionally paste your own measured GHI values to override ERA5.

Format: {"YYYY-MM-DD HH:MM:SS": value_in_watts_per_m2, ...}
Measurement Data Format

Provide hourly solar irradiance measurements in W/m² for the last 3 days:

  • Use ISO datetime format: YYYY-MM-DD HH:MM:SS
  • Values should be in W/m² (Watts per square meter)
  • Include only daytime hours (6:00 - 19:00)
  • More data points = better validation accuracy
Data Sources

You can obtain measurement data from:

  • Local meteorological stations
  • Solar power plant monitoring systems
  • NASA POWER database
  • PVGIS solar radiation database
ERA5 Comparison Results
Metrics below reflect agreement between the fuzzy system and the ERA5 reanalysis model — not against physical sensor measurements. Lower RMSE means the two models agree more closely.
