4 INSTALLATION NOTES
The housing is designed to be installed on a 36 ÷ 52 mm diameter pole. The tripod kit
HD2005.20 (height 2 m) or HD2005.20.1 (height 3 m), in anodized aluminum with adjusta-
ble legs for levelling, allows installing both data logger and sensors.
1. Trees, buildings and obstacles on the sun
path, from dawn to sunset, must be less than
5° on the horizontal plane.
2. Trees, buildings and obstacles surrounding
anemometers must be at a distance of at least
10 times their height, to avoid turbulences.
3. Solar panels and solar devices must not be
overshadowed. Always orient them towards
the SOUTH in the northern hemisphere and
towards the NORTH in the southern hemi-
sphere.
4. Rain gauges or evaporation basins must be
placed in open areas and far from any ele-
ment that could create shadow or turbulence.
1. Wrong orientation of solar radiation meas-
urement devices: all devices must be orient-
ed towards the SOUTH in the northern hemi-
sphere and towards the NORTH in the south-
ern hemisphere. There should not be pro-
jected shadows on the solar panel or the py-
ranometers.
2. Trees or buildings near the station creates
turbulence, measurement of air velocity and
wind direction can be wrong.
3. Wrong position of the rain gauge. Install far
from the station.
1. Wrong position of the pyranometer. It alters
the anemometer’s measurement. Lower the
pyranometer’s clamping and rotate it by 90°
in order to avoid any turbulence on the ane-
mometer.
2. Wrong position of the solar panel towards
the North: orient it towards the South (in the
northern hemisphere).
3. Wrong position of the rain gauge. Install it
far from station.
