Yield Forecasting
Ensemble models blend satellite irradiance, aerosol depth and micro-weather into day-ahead forecasts calibrated to 3.1% MAE.
- NWP + satellite fusion
- 15-min and hourly horizons
- Auto-recalibrating per site
CHEECHEE·OS · Now serving 11.4 GW across 24 markets
The operating layer
for photovoltaic assets.
CHEECHEE·OS is the AI platform utility, C&I and floating-PV operators run their fleets on. Forecast yield to within 3.1% MAE, catch degradation weeks before performance ratio drops, and dispatch to the market that pays best. Modules, when you need them, come from our own Greater-Bay line.

01 · Thesis
The next percentage point of solar yield won't come from silicon. It comes from software.
Photovoltaic hardware has plateaued near its theoretical ceiling. The remaining gains — 8 to 14 percent in real-world energy output — sit inside operations: soiling forecasts, inverter clipping, string-level degradation, curtailment, tracker angles, dispatch. CHEECHEE·OS is the software layer that recovers those gigawatt-hours. When customers want us to close the loop, we ship modules from our Greater-Bay line too.

Four modules. One operating layer.
Anomaly Detection
Computer vision on drone and CCTV feeds spots soiling, hot-spots, PID and micro-cracks weeks before performance ratio drops.
- Drone EL + IR ingestion
- String-level fault triage
- Auto ticket to CMMS
Digital Twin
Every string, inverter and tracker mirrored in a physics-based twin. Simulate curtailment, dispatch and battery pairing before capex.
- Physics-based module model
- Co-located BESS sizing
- Capex scenario library
Dispatch & Trading
Native connectors to major APAC power desks — auto-bid, curtail, or shift to co-located BESS to capture peak pricing.
- HKEX-adjacent, USEP, NEM, CAISO
- REC & PPA settlement
- 24/7 carbon-matched accounting
03 · Hardware, when you need it
A 3.2 GW automated line, ninety minutes from Central.
Software runs best when it can talk to the hardware. Our Dongguan facility runs a fully-automated TOPCon-N and heterojunction (HJT) line, feeding modules that are pre-instrumented for CHEECHEE·OS — string-level telemetry from day one, no third-party gateway required.
