Cloud-powered performance analytics for minute-level insights
At Terabase, we believe that solar projects should perform exactly as designed—every minute, every hour, every day. That’s why we built SCADA PlantPredict, a cloud-powered performance analytics solution that gives owners, operators, and EPCs minute-level insight into how their plants are really performing.
Unlike regression-based models or post-processed analytics, SCADA PlantPredict runs a live digital twin of your solar project, using only weather data inputs. This simulation is continuously compared against actual SCADA-measured performance, so you can pinpoint performance gaps the moment they occur.
Why Real-Time Modeling Matters
Most solar performance monitoring relies on hourly averages or regression models that mask shortfalls. By contrast, SCADA PlantPredict delivers minute-level accuracy. That means operators can see deviations faster, isolate problems earlier, and minimize lost production.
With its physics-based modeling engine, PlantPredict quantifies exactly what your plant should be producing—down to the array and inverter level—and compares it to what’s actually delivered. The result is clear, actionable intelligence.
What SCADA PlantPredict Detects
- Inverter derating or overheating.
- Weather-driven tracker stows versus actual stow behavior.
- Curtailment events and associated lost energy.
- Component failures or disconnects at the inverter or block level.
How it Works
1. Weather Data Sent to the Cloud: SCADA transmits timestamped, averaged site weather data (irradiance, wind, temperature, humidity, soiling, etc.) via secure API.
2. Model Runs in the Cloud: The PlantPredict digital twin simulates expected performance under those exact conditions.
3. Modeled Data Returned to Site: Modeled outputs are delivered back at one-minute intervals for system, array, and inverter levels—ready to compare with measured SCADA data.
Who Benefits
- Performance Engineers – Diagnose deviations at the component level without waiting for offline analysis.
- Commissioning Teams – Validate compliance with contract availability & KPIs in real time.
- O&M Teams – Isolate underperformance, misalignment, or tracker stow issues instantly.
- Asset Managers – Quantify energy loss for PPA enforcement and insurance claims.
Core Advantages
- Minute-Level Accuracy – Avoid 1–4% errors hidden by hourly averaging, critical in variable weather.
- Component-Level Precision – Compare expected vs. measured output at system, array, and inverter terminals.
- Clear Loss Attribution – Quantify lost energy from curtailment, tracker misalignment, or inverter derates.
- Commissioning Validation – Confirm EPC turnover and ongoing compliance at the minute-level.
