Installation
Weather Station
Mount the support mast securely. This may be done by using the Mono-Mount or Tripod,
which is sold as an accessory to the PV -100-2. The mast may also be attached to a
MET
support structure using U-Bolts. Do not tighten the support structure to the PV -100-2
MET
unit; it will need to be oriented to the correct direction.
Rotate the assembled unit until the electronics enclosure faces TRUE SOUTH or TRUE
NORTH if you are in the northern or southern hemisphere, respectively. Secure the
support mast to the assembly. Rotation is prevented by lining up the two holes in each
mast.
Irradiance Sensor
The pyranometer is attached to the sensor assembly
and when orientated correctly will measure global or
plane or array irradiance. To accurately measure this
quantity, the sensor must be adjusted to the
appropriate angle. This is done by using a 5/32" or
4mm Allen wrench to loosen the adjustable mounting
bracket to the correct angle.
PV Temperature Sensors
This sensor is designed to attach directly to any solar
panel. When placed on the center of the back of the
panel, it accurately measures the temperature of the
panel.
Prior to installation of the PV temperature sensor onto the
PV panel, the installation area of the panel back should
be thoroughly cleaned. This cleaning will ensure a good
bond between sensor and panel and allow for accurate
panel temperature readings.
After cleaning, peel off the protective adhesive tape on
the temperature sensor and stick it onto the panel. Firmly
press the sensor into place. Refer to the picture below.
The cable should be secured within 8 inches of the
temperature-sensing element.
Run the cable back to the PV -100-2 unit and connect
MET
to the PV temperature sensor terminals.
