5.5.2 Orientation and Inclination of the Solar Panel
In order to ensure that the solar panel is receiving the most amount of light for its location, its
orientation must be taken into account. Follow the steps below to make sure the solar panel is correctly
positioned and angled.

The panel can be installed in a sunny location at any height; 1.6-2.0 m makes it easier for
maintenance and cleaning. The panel does not come with a mount for the tower so a single arm side
mount should be purchased locally for this purpose (see Appendix A.1). The panel can also be
installed on a pole by itself or close to the ground as long as the facing direction and angle guidelines
are strictly followed (see Table 4 below).

To maximize the capture of direct solar radiation, angle the solar panel with respect to the
ground using the guidelines in the table below (only values relevant to tropical locations shown).

5.6 Installing the sensors
There are two main steps involved in the installation of the sensors: first, the sensor should be
adequately positioned on a mounting bracket and attached to the tower and then the cable from the
sensor should be connected to the data logger. Below, we describe the main steps to mount each
sensor. Refer to the documentation enclosed with each sensor for more detailed instructions. R

for each sensor installed because this information will
need to be uploaded to the TEAM portal upon return from the field. The
Sensor Installation/Calibration
Form
can be used to record this information. Fill in all of the required information (i.e. date, activation
time, recording person, serial number, etc.) and keep in mind that this form is also used when
removing sensors for calibration, so make a note that these sensors are being installed for the first time
on the field form so there is no confusion.

Use a clinometer to ensure the correct tilt angle. For example, it the
station is located 15 degrees north of the equator, the solar panel should be
facing south and angled at 20 degrees from the horizontal.
