If the internal battery of the solar panel is charged, the
camera will be immediately powered.
It is strongly recommended that the batteries be installed
inside the camera even when connected to the solar panel.
Otherwise, the camera may stop operating due to power
shortage. During intensive use of the camera, the soar panel
internal battery may not be charged fast enough, and
therefore, the solar panel is not ideal to be used alone
without the batteries. The energy from the solar panel is
consumed first, before that from the batteries.

Installation
Adjust the angle of the bracket so that the solar panel is
directly facing the sun. Generally in the northern
hemisphere, this means the panel is facing south. For a
maximized performance, ensure the solar panel is facing
south, in an un-shaded position and ideally tilted at a 45
degree angle. This will prevent the need to change its
orientation every season and ensure its continued
efficiency. However, please note that the ideal orientation
depends on the specific situation of the set-up site.
Do not install the solar panel in a location where the sunlight
may be blocked from getting to the panel.
