Mounting the additional
Solar Panel
If you are adding the panel to an All Purpose Ventilator
(gable fan) or a roof mounted fan such as the Solar Powered
Attic Fan or Roof Mount Attic Fan be sure to measure the
distance before installing
Using with gable

The Solar panel unit comes with 30 ft. of wire. It is a good idea to measure the distance from the
fan’s motor and where you’ll be installing the panel to make sure you have enough wire to cover the
span. (between a. and b. on fig. 1 & 2)

Selecting the best location
for the additional panel
We’ve designed the add-a-panel to allow you the flexibility to place it where you can get the best exposure to the sun during the
course of the day. You can place it on the opposite side of the roof or an exterior wall that gets the sun exposure in the morning or
afternoon. Survey your home to determine the best location for the extra panel. If the first panel gets morning sun but no afternoon
sun, install the second panel where it will get exposed more to the afternoon sun and vice-versa. This will keep the fan running for
much longer periods during the day.
Surface mounting on composition roofs:
Step 1.
Loosen and remove screw A (both sides) to allow the panel to swing away from the base.
Set the screws aside. (fig. 3)
Step 2.
Before mounting, make sure to pull the wire back through the hole in the center of the base so the base can lay flat on the roof surface
when installed. (fig. 4)
Step 3.
Mount the base using four 3” galvanized screws making sure to seal the screw holes with a roof tile adhesive as shown. Tilt the panel
away from the base while installing the screws. If the panel is to remain flat against the base when installed it is recommended that
you allow the roof tile adhesive to completely dry before contacting with the panel. (fig. 5 & 6)

Surface mounting for S-Tile, Flat Tile or Metal roofs
Step 1.
Determine the location of the contact points by positioning the panel in the desired area. For S-Tile roofs, find a position with as much
surface area coming in contact with the bottom of the panel as possible. The panel must be mounted on at least 2 rows of tile as
shown. (fig. 7 & 8)
Step 2.
Apply enough roof tile adhesive to the underside of the base to firmly secure the panel to the surface. Both surfaces should be dry
and free of any dirt or solvents. (fig. 9)
Step 3.
The panel can be tilted into two positions with the adjustment arm, chose the best angle and reinstall the adjusting screws (screw A). (fig. 10)

Wall mounting:
Brackets are included to mount the panel to a wall if preferred.
First, assemble the braces to the brackets as follows:
Step 1.
Attach the brace to each bracket with the cross brace bolt and nut (E.) (fig. 11)
Step 2.
Attach the brackets to the panel using the 4 bolts (F.) (fig. 12)
Step 3.
Depending on the material your wall is made of, mount the assembly to the wall using appropriate fasteners
(see “Optional Hardware” on page 1 for details). (fig. 13 and 14)

Connecting the motor and two panels
with the Y-Adapter
The Y-adapter allows 2 solar panels to be connected in parallel to the motor. This
does not double the voltage to the motor - it simply provides another power source to
allow the unit to operate for a longer period of time during the day.
A. For the 9910APV:
Step A1.
Connect the leads of the first solar panel to the Y-Adapter
as shown in (fig. 15 & 16) Make sure to connect black to
black and red to red, etc.
fig. 15
Step A2.
Connect the leads from the second panel (fig. 16) to the
Y-Adapter in the same fashion. If necessary, use a piece
of electrical tape to cover the black leads so they don’t
touch the red leads when everything is connected.

Step A3.
Connect the other end of the Y-Adapter (fig. 17) to the
motor make sure to connect the black lead to the black
post and red lead to the red post. (fig. 18)
fig. 16
B. For the 9910TRP:
Step B1.
An access point is located under the shroud to allow for
connecting an extra panel. (fig. 19)
Cut the zip ties that hold the wires to the frame. (fig. 20)
fig. 19
Step B2.
Disconnect the panel leads from
the motor leads. (fig. 21)
Step B3.
Now connect the Y-Adapter as
described in steps A1 - A3 to the
motor and panel leads as shown
in (fig. 22)
Step B4.
Bundle and re-attach the wires to
the rodent screen with zip ties.
