1.1 Concerns BEFORE Installation
Correct positioning of the solar panel will determine the efficiency of the system. In general, the panel should be facing TRUE
SOUTH at a specific TILT ANGLE towards the sun using the information provided on the next page to achieve the highest
efficiency. Some re-adjustment of the panel might be necessary to over time to “Fine Tune” the systems efficiency. The solar
panel should be installed as close as possible to the control box in an area free and clear of ALL obstructions and shadows
during the ENTIRE day. Generally, If the solar panel is NOT in sunlight, the batteries are NOT being charged.
• Trees / Buildings that do not block the solar panel from direct sunlight in the summer,
could block the panel during the winter. The sun’s path across the sky is lower during the winter
than in the summer. The shadows that do not obstruct the solar panel during the summer
months, will cast longer shadows in the winter, which could block the panel then.
• Wind can exert extreme pressure on the solar panel and support post. Make sure they are
securely fastened.
• Dust can accumulate on the panel over time. Cleaning the panel every so often is necessary to
keep the system operating at its highest efficiency.
• Snow may cover the panel during the winter. You may want to re-adjust the panel to a steeper
angle to allow the snow to slide off. Even then, the panel may still accumulate snow and need to
be manually cleaned off when necessary to keep the system functioning.

Recommendations
The solar panel will perform MOST efficient when
installed as close as possible to the control box
(Within a couple of feet). Installation can be a maximum of
100 ft away from the box if necessary using a minimum 18
gauge wire run. Keep in mind, the efficiency of the solar panel will
diminish the farther away the panel is installed from the control box.
Solar Control Box Requirements:
• (1) ONE 24 Volt 10 Watt Solar Panel (P/N 2000-077) for 18 Amp/Hr Batteries.
• (1) ONE 24 Volt 20 Watt Solar Panel (P/N 2000-076) for 35 Amp/Hr Batteries.
