The PVmet-200 is our commercial model option. It features sensors specific to PV power generation. This low cost station is compact and simple to install.
Features:
- Adjustable Solar Global Irradiance Sensor
- Plane-of-Array Irradiance Sensor
- Back-of-PV Panel Temp Sensor (A second back-of-panel sensor may be added for an additional charge)
- Also includes Ambient Air Temperature Sensor, Wind Speed sensor and Wind Direction Sensor
- Modbus RS-485 Communication
- SunSpec Certified
Sensors:
- Ambient Air Temperature: Housed in a passive solar shield.
- Global Irradiance: The irradiance sensor is adjustable and can be set to provide global irradiance.
- Plane-of-Array Irradiance: A separate plane-of-array sensor is supplied with a mounting bracket to attach to the side of the PV panel.
- Back-of-Module Temperature: These sensors are attached to the back of the PV panel using thermal conductive adhesive tape. They provide accurate panel temperatures, an important parameter for
efficiency monitoring. One sensor is shipped with each system, but the PVmet-200 supports two sensors if desired.
- Wind Speed and Direction: A mini-airvane anemometer provides both wind speed and direction information.
