If this is not possible, try to choose a site where any obstruction over the
azimuth range between earliest sunrise and latest sunset has an elevation not
exceeding 5°. Diffuse solar radiation is less influenced by obstructions near the
horizon. For instance, an obstruction with an elevation of 5° over the whole
azimuth range of 360° decreases the downward diffuse solar radiation by only
0.8%. The sensor should be mounted with the cable pointing towards the
nearest magnetic pole. For example, in the Northern Hemisphere, point the
cable toward the North Pole.
6.2 Installation
1.
On a level surface, level the solar radiation sensor using the leveling feet
on the sensor. Alternatively, remove the sensor leveling feet to allow it to
be mounted directly to the mounting bracket. Smaller sensors, such as the
CS301, do not have leveling feet and must be mounted directly to a
leveling base.
2.
Secure the solar radiation sensor to the mounting bracket. Refer to
to determine which mounting holes are used by the sensor.
Visually inspect the leveling feet on the sensor (if present) to ensure all
feet are in contact with the mounting bracket.
