Component-level model
PVLib-derived module physics, calibrated to each SKU's IV curve and temperature coefficient — including our own Aurora, Meridian and Delta lines.
CHEECHEE·OS
The operating layer
for photovoltaic assets.
Four tightly-coupled modules — forecasting, detection, twin, dispatch — running on a single time-series backbone. Deployed across 11.4 GW in 24 countries, typically live in a customer's fleet within eight weeks.

01 · Yield forecasting
Ensembles, not point predictions.
We fuse four numerical weather models, geostationary satellite irradiance (Himawari-9, GK-2A, GOES-18), aerosol depth from CAMS, and site-level pyranometer telemetry. Each forecast is issued as a probabilistic ensemble — day-ahead, hour-ahead, and 15-minute rolling — so trading desks can bid with confidence intervals, not point guesses.
- 3.1% MAE day-ahead, benchmarked quarterly
- 15 min intraday recalibration cadence
- P10 / P50 / P90 bands on every horizon
- API-first — REST, WebSocket, Snowflake share
02 · Anomaly detection
Catch it before PR drops.
Computer vision models trained on 4.8M labelled panel images spot soiling, hot-spots, PID, snail-trails, and micro-cracks in EL, IR and RGB imagery. String-level telemetry is cross-referenced against the digital twin — so a drop of 0.4% in PR triggers a diagnosis, not just an alert.
- 4.8M labelled defect images in training corpus
- 72 h mean lead time before PR loss materialises
- Auto ticket dispatch to Maximo, IBM TRIRIGA, Fiix
- DJI, Skydio, Wingtra drones supported out of box
03 · Digital twin
A physics model of every asset. Simulate before you spend.
Each module, string, combiner, inverter and tracker is mirrored in a physics-based twin. Change the tilt, add BESS, re-string a block — see the yield delta before you sign a purchase order. Twin state is versioned, so you can replay any failure hour-by-hour and share the timeline with your O&M contractor.
Scenario library
Pre-built scenarios: 2h/4h BESS pairing, single-axis retrofit, agrivoltaic co-location, floating conversion — with cash-flow output.
Replay & forensics
Every twin state is snapshotted every 5 min. Investigate incidents against the exact irradiance, temperature and inverter state that occurred.
Curtailment simulator
Model grid-operator curtailment orders against your bid stack and BESS state-of-charge. Optimise your day-ahead offer curve overnight.
