PVMet™ 100 Solar Monitoring Station


The PVMet™ 100 includes all the same sensor options as the PVMet 75 but offers an adjustable EKO ML-01E Irradiance Sensor that can be set to provide Global or Plane-of-Array Irradiance. The adjustable option provides installers the flexibility to match the sensor to the PV panel angle. Compact and simple to install on any solar project, the PVMet 100 connects to Modbus RTU Communication with an ethernet TCP option available. Ships fully assembled and factory calibrated.

Sensors & Options

Global Irradiance or Plane-of-Array Irradiance

The adjustable irradiance sensor can be set to provide global when horizontal, or plane-of-array irradiance when installed to match the PV panel angle.

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. The PVMet 100 supports two sensors. The second may be purchased separately.

Ambient Air Temperature

The ambient air temperature sensor is housed in a passive solar shield for increased accuracy.
