Position
The location of the panel(s) is critical to the success of the installation. In
general, the panel(s) should be mounted using the provided angle bracket
facing due south. The solar panel(s) should be mounted in an area clear of
all obstructions and shade from buildings and trees. If the panel(s) is not
casting a shadow, the battery is not being charged.
NOTE: Tall trees or buildings that do not shade the solar panel(s) in the
summer could shade the solar panel(s) during the winter months when the
sun sits lower in the sky.
Sun's position
