Installation - Chamberlain SP10W12V Installation Manual

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
