Solar Panel Installation

IMPORTANT: the solar panel must be positioned facing the path

of the sun, due south and in an open area away from shade. It should

receive at least 8 hours of direct sunlight for a full charge.

HINTS for Obtaining Maximum Output from Your Solar Panel

1. Place the panel facing due south in the path of the sun, where full sun will strike its face throughout the

day(minimum 8 hours).

Mount the panel using the curved pipe provided to maintain the proper angle to the sun.

3. For optimal efﬁciency, wipe the face of the panel frequently with a soft, damp cloth. The output of the

Solar Panel is variable during the day depending on the intensity of the sun and the angle of the rays

striking the panel. The output may vary from a few millivolts to as much as 22 volts. To check the output,

simply disconnect the solar panel leads from the control board and connect them directly to a dc voltmeter.

In bright sunlight the panel output should read at least 18 volts dc at approximately 300mA.

HINT: If the solar panel must be placed more than 10 ft. from the

control box (but less than 250 feet away), use multi-stranded, 16

gauge (AWG), direct burial, low-voltage wire RB509 (see Accessory

Catalog). Never use telephone wire or solid core wire.

IMPORTANT: To provide secure and moisture resistant splices for

solar panels use a direct burial splice kit for underground splices and

an above ground splice kit for above ground splices. These splice kits

can be found at hardware and electrical supply stores.

Step 1: Slide the

/4" bolts (F) through the bottom of each channel so threaded part of each bolt comes through

top of frame, position the pipe (D) between the bolts and place two clamps (C) over the curved pipe onto the bolts.

The clamp at the top of the solar panel should ﬁt over the pin on the curved pipe. Secure with the

/4" nuts (E).

Step 2: Determine the site for installation of the solar panel. It is

important to install the solar panel facing the path of the sun where

full sun will strike its face throughout the day. The solar panel cannot

be shaded out or obstructed by trees, bushes, buildings etc for any

part of the day. The curved pipe (D) maintains the proper angle to the

sun. Secure the solar panel assembly to a wooden post or fence using

two pipe clamps (C) and #2 lag screws (B) as shown in the illustration.

If your fence post is metal, you will need alternative hardware not pro-

vided, (i.e. U-clamps or metal screws).
