PVSyst told you how much your plant would produce.

We tell you what it can produce today.

With Quadrical Digital Twins. Commissioning models set your plant's production baseline — then, by layering in real-world conditions and recalibrating in real time, Quadrical builds a live, personalized benchmark down to every sensored device on your plant.

The Problem

Operations need accurate loss calculations.

Project Finance used PVSyst to set commissioning numbers for investors. Those contracted numbers are now the O&M benchmark — and your team needs to attribute losses accurately against them for the next 25 years. Some losses stay invisible to SCADA and performance reports, yet still become expensive problems.

String-level drift

A string producing 3–5% below its neighbors doesn't trigger an alarm — but it compounds.

Temporal anomalies

Shading at 7am lasting until 9am. Unusual soiling patterns tied to string orientation.

Degradation

The gap between working and working at full capacity — measurable only with a device-specific benchmark.

Long-term decline

An inverter getting slightly worse each month never crosses an alarm threshold — visible only across years of twins.

SoH erosion

A battery pack degrading faster than its design baseline — no alarm, just gradual cycle-cost increase.

Invisible, not absent

These losses weren't hidden. They were just invisible to the tools used to find them.

$126,078

In a 9.26 MW plant audited over 3 months, Quadrical's Digital Twin AI found 620 MWh of undetected generation capacity — $126,078 of recoverable yield. This older, high-PPA plant had been continuously monitored the entire time.

The Solution

An accurate virtual data replica. Unique to every device. Always on.

A Quadrical Digital Twin is a unique model created for every physical device in your portfolio — inverter, string, battery cell node. It learns exactly how that specific device behaves, using peer behavior, age, degradation history, and operational characteristics.

A typical 50 MW solar site may run hundreds of individual twins — one per device, per job.

When an inverter starts clipping earlier than it should, a string's performance drops below its peers, or a battery's round-trip efficiency slips — Quadrical Digital Twins catch it, classify the deviation, quantify the revenue impact, and generate a ticket. Because our model always knows what that exact device's "normal" looks like.

Monitoring vs. intelligence

This is the difference between just watching a number and understanding what it means. Quadrical builds this intelligence directly into your Asset Management platform — it's not something you pay for separately. Manage your whole fleet and optimize each asset. Continuously. Automatically. In real time.

Wonky Details

For those who go deeper.

+

No single model can catch every type of fault. Long-term degradation requires peer comparison over months. Acute faults require real-time deviation from an asset's own expected curve. Quadrical runs both simultaneously — two independent models per device, for every data interval.

The DEAR model

Dynamic Environment – Action – Response. Trained on that asset's own data — not fleet-average shortcuts or generalized guesses.

Clean data, first

Every raw stream passes through a quality pipeline before training. Curtailment periods, sensor dropouts, and communication glitches are identified and removed so the twin baseline stays uncontaminated.

Resolution & retraining

Data ingested at 15-minute resolution, configurable to 1-second for high-sensitivity assets. Structural Twins retrain monthly, Temporal Twins weekly — with an immediate refresh triggered by maintenance events.

Two models. Every asset. Every interval.

Catching long-term degradation

For asset managers, gradual degradation is both commercially significant and the hardest to see. A module cluster losing a fraction of output monthly triggers no alarms — just silent, compounding losses multiplying across the portfolio.

How it catches it: by watching how one device performs relative to its peers — comparable devices at the same plant, under the same conditions. Underperformance against that group is a structural signal. The baseline recalculates monthly to absorb seasonal effects.

Structural Degradation Ticket grey band = peer range dotted = peer median · solid = asset actual

Sustained divergence from peers. Caught before it compounded.

Catching real-time faults

Where the Structural Twin catches degradation over time, Temporal Twins catch faults in minutes. Running at 15-minute intervals, they compare device production against what it should be — based on the asset's own learned behavior and current peer performance.

If gaps sustain across consecutive intervals, an automatic Temporal Performance Ticket is issued. Extra care around consecutive-interval requirements prevents false tickets from transient shading, meter glitches, or momentary grid events.

Example: a device with a partial bypass diode failure six months ago would trip a fleet-average model every single day. Because Quadrical trains on post-failure baselines, only genuine new deviations generate a ticket — so your team can fully trust every alert.

Temporal Performance Ticket dashed = ML-predicted curve · solid = actual output

Fault detected in the same interval it occurred.

Isolating inverter faults

An inverter's job is to convert DC power from strings into AC power for the grid. The right measure of whether it's doing that job is efficiency — AC output divided by DC input — not normalized power.

This matters: if an upstream string fault reduces DC input, a normalized-power model would flag the inverter as underperforming when it's actually just doing its job. By measuring efficiency, the Inverter Twin evaluates only what the inverter itself is doing — alerts are double-checked against upstream SCB deviations, so your team gets clean, correctly attributed tickets.

Normalized Power Model Efficiency Model String / SCB Inverter flagged ✕ SCB fault Inverter correct ✓ Root cause misattributed Root cause correctly isolated

The right metric for the right fault.

Threshold Configuration

Deviation thresholds are configurable per asset, per plant, per asset class. High-value assets may warrant tighter thresholds; assets in high-variability environments can use widened thresholds to prevent alarm fatigue. If you carry generation guarantees or PPA obligations, sensitivity can be tuned to protect your exposure. Every threshold change is version-controlled and timestamped.

Ticket Contents

Every ticket is a complete evidence chain — from raw data to its triggering deviation.

Structural Degradation Ticket

Asset ID, SCB or string reference, deviation % from peer baseline, peer group reference, historical trend chart, suggested inspection actions.

Temporal Performance Ticket

Asset ID, timestamp, deviation % from ML prediction, predicted vs. actual generation values, intraday trend chart at the moment of fault occurrence.

Before & After

What changes on day one.

Quadrical doesn't replace your O&M workflow — it makes every step of it accurate.

Before Quadrical
Reactive O&M — faults identified after generation loss has already occurred.
Weekly or monthly PR analysis — missing intraday events.
Alarm fatigue with generic alarms, high false-positive rate.
No peer context — impossible to distinguish asset-specific degradation from site-wide trends.
Inverter faults attributed manually, slow root-cause resolution.
With Quadrical
Proactive O&M — Temporal Twin detects faults in the same 15-minute interval they occur.
Continuous automated analysis. 24/7 for every asset, every interval.
High-precision tickets. False-positive suppression with dual lookback and context-conditioning.
Peer benchmarking — structural degradation isolated from site-wide effects.
Automated fault attribution — SCB vs. inverter cause identified at ticket creation.
One Platform
