INSTALLATION 

 

Select a location that provides maximum exposure to sunlight. In the northern hemisphere, the front 
surface of the panel should face south. In the southern hemisphere, the panel should face north.  
 
Shade on even a small portion of the panel surface greatly lowers the efficiency of the panel, so avoid 
placing the panel near or under trees, buildings, or any other objects that cast a shadow. 
 
Avoid placing the panel below structures where birds will perch. If birds use the panel itself as a 
landing spot, it may be necessary to apply a spike strip along the top edge of the mounting bracket to 
keep the panel from being covered with bird droppings. 
 
Regular maintenance includes cleaning the top surface of the panel whenever dust or debris collects. 
Place the panel at a height where it is not difficult to reach for regular cleaning. 
 
The 320-900 Solar Panel mounting bracket is adjustable so that the optimum 
angle for a particular latitude can be achieved. The best angle varies throughout 
the year, however a good compromise can be reached by determining your 
coordinates and entering them into an on-line calculator. One such calculator 
can be found at:

Instructions for assembling the mounting bracket are not included in this 
manual, but may be on a separate instruction sheet included with your panel. 
 
Assemble the panel and mounting bracket onto a vertical mast or tower (sold separately), and make 
sure the face of the panel points south (northern hemisphere). Adjust the tilt angle, then tighten all 
bolts. Route the cable to the logger or battery box, and secure the cable to the mast at 2' intervals to 
prevent the cable from whipping in the wind.

CONNECTION  

 

CAUTION  – Connect battery power to the logger BEFORE connecting the solar panel to the system. 

Otherwise the logger may not "boot" properly, or excessive voltage may be applied to 
the logger system. Do the reverse when powering down, i.e. disconnect the solar panel, 
and then unplug the battery to turn off the logger. 

CAUTION  – The solar panel produces electricity whenever it is exposed to sunlight. There is always 

the  danger  of  short-circuiting  which  could  cause  sparks  or  damage  to  other  electrical 
equipment  if  not  connected  properly.  It  is  advisable  to  cover  the  solar  panel  with  an 
opaque cloth while connecting the cable.

 

The 320-900 Solar Panel cable is provided with a 2-pin quick-connect plug which makes connection to 
NovaLynx loggers a simple matter. The plug not only provides insulation which helps prevent sparks,
