Sensors & Options

Global Irradiance or Plane-of-Array Irradiance

The irradiance sensor is adjustable and 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 150 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.
