Battery: To protect the battery from the elements, it should be placed in a separate plastic/metal
container with slits/holes to allow airflow (a plastic car battery enclosure can be purchased
locally). Since lead-based batteries leak small amounts of hydrogen gas when charged, creating a
potential fire hazard, it is very important to provide appropriate ventilation. The battery and
its enclosure can be mounted on the side of the tower or sitting on the ground and appropriately
secured (e.g. chained). The battery should NOT be installed inside the same enclosure as the
data logger. There is a short section at the end of the video called “Installing the solar panel and
the battery” on the TEAM portal in the Climate Protocol section that describes battery
installation procedures (http://www.teamnetwork.org/en/protocols/threat/climate). This video
also has information about installing the solar panel.
3.11 Installing the Solar Panel
Equipment/supplies needed:
• Wrench
• Solar panel (SP10)
• Solar panel mount
• Compass
• Clinometer
The solar panel should be installed in a way to maximize exposure to sunlight and ensure the
station can run on solar power during the day. Please see the video mentioned above for more
information about installing the solar panel. The following sections detail how to connect the
solar panel to the charge regulator and angle the solar panel to receive the most light.
3.12 Connecting the Solar Panel to the Charge Regulator
Equipment/supplies needed:
• Screwdriver
• Charge regulator (PS100)
• Wires to connect battery/solar panel
• Wire cutter/stripper
• Plastic cable ties
• Electrical tape
In order to safely connect the battery and solar panel to the charge regulator it is very important
to follow the steps below in the order they are written. Instructions can also be found on page 5
of the charge regulator’s operating manual.
1. Install the charge regulator. Before mounting the solar panel to the tower, install the
power regulator (PS100) in the enclosure above the data logger. This ensures that the
current coming from the panel is regulated and the current from the battery does not drain
to the panel. WHEN INSTALLING THE REGULATOR MAKE SURE THE
PANEL IS COVERED OR FACING DOWN TO AVOID EXPERIENCING
ELECTRIC SHOCK.
