TIP:
The area around the solar panel(s)
should be clear of shadows or obstructions
to the sun for a 180° arc east to west.
INSTALLATION
Solar panel(s) MUST be installed facing south. Use a compass to determine direction. Below are general instructions for installing the
solar panel(s). Your installation may vary slightly depending on the solar panel purchased.
1. Position the mounting bracket on the mounting surface. Mark and drill holes.
2. Secure the solar panel to the mounting bracket using the hex bolts, hex nuts and washers provided.
3. Secure the solar panel to the mounting surface using lag screws provided.
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.
