Data Integration & Metrology Standards
Our solar metrology instruments are engineered to feed real-time, high-fidelity data directly into your SCADA systems, ensuring your plant meets international performance evaluation standards.
| Sensor Type | Output Signal | Plant Impact |
|---|---|---|
| Pyranometer | Modbus RS485 / 4-20mA | Provides the baseline GHI data required to calculate the absolute maximum theoretical yield of the plant. |
| Reference Cell | mV / Modbus | Offers instantaneous irradiance changes, matching the exact spectral response of the active PV panels. |
| Wind Anemometer | Pulse / RS485 | Prevents catastrophic mechanical damage by signaling single-axis trackers to stow horizontally during high winds. |
| Back-of-Module Temp | PT100 (4-Wire) | Used to calculate power loss due to thermal degradation (typically -0.3% to -0.5% per °C above STC). |
