W IND S PEED S ENSOR
Once a well exposed site, reasonably free from surrounding obstacles, has been found, the wind direction and
wind speed combined sensor should be mounted at a height of 10m from the ground on a special structure, as
suggested by the WMO.
By positioning the sensor on top of the pole, you can get a rather precise idea of what happens at the PV
modules height. Make sure that obstacles, if any, are located at a minimum distance of 10 times the height of
the sensor (over 30m in our application).
The sensor is supplied with a cup rotor, a weather vane rotor and a 7-pole shielded cable.
Do the following to install the sensor:
•
Mount the cup rotor on the sensor body and fasten it by tightening the internal grub screw on the rotor
side with the hex key supplied with the sensor
•
Mount the weather vane rotor on the sensor body and fasten it by tightening the screw on top of the
tacho-anemometer. Make sure that the tooth of the weather vane fits into the special hole on the
support pin
•
Run the screened cable inside the pole and make sure that the 7-pole female connector exits from the
pole head
•
Connect the cable to the sensor
•
Mount the sensor on the pole head. Set the red tip to north and fasten the sensor by tightening the
sensor screws with a 10 metric wrench
•
Connect the tacho-anemometer to the E-Log as detailed in section 6.3 Connecting the Sensors to the ELog.
