Plane of array (POA) and rear plane of array (RPOA) mounting

Irradiance sensors are used for the optional plane of array (POA) and rear plane of array (RPOA) measurements. Several irradiance sensors and mounts are available. As an example, this section shows the irradiance sensors being mounted directly to the solar panel using the CM268 mounting bracket. Campbell Scientific also offers the CM261 Single-Axis Tracker Mounting Stand and CM266 Unistrut Mount.

1. Mount sensor on CM268 plate.

   

2. Place CM268 solar panel lip.

   

3. Tighten nuts to secure the bracket to the solar panel.

4. Use the sensor bubble level to level each pyranometer using the adjustment screws of the CM268 mount.
