P.O.A. sensors can be mounted to the solar array or separately. If the solar panels are mounted on a tracking system, then the P.O.A.
sensor must also be mounted on the tracking system. If the solar panels are not on a tracking system, then the angle of the panels can
be measured and the P.O.A. sensor set to the same angle but will have to be readjusted if the panels alignment is changed seasonally.
For diffuse or ground reflected sensors follow the instructions that come with the sensor.
Each solar irradiance sensor will come with directions for proper mounting and they should be followed carefully.
BACK OF MODULE TEMPE RATURE SENSORS
The back of module temperature sensors (B.O.M) are 2-wire, resistive NTC devices. Sensors should be mounted near the center of the
panel to more accurately represent the overall average panel temperature. The sensors are provided with thermally conductive
adhesive tape. Epoxy cement can be used if desired, but this will make removal/replacement difficult.
