-Some vehicles are factory-installed with roof cable entry
points.
-If a cable entry point is absent, factory-installed vents can be
used to route cables through.
b. Locate a suitable location for the charge controller inside the
vehicle. Select an area that is readily accessible, viewable, and
free from exposure to moisture.
c. Plan the route and measure the lengths of cables needed to
reach their connection points factoring in bends and slack.
d. You may add additional solar panels. For more information,
see Solar Panel Wiring on page 7.

3.Mount the solar panel.
TIP 1: Once applied to a surface, any industrial
grade outdoorUV-rated adhesive sealant
cannot be easily removed without damaging
the solar panel.
a. Unpack the solar panels and prepare all installation tools and
materials.
b. Prepare the roof mounting surface by removing dust, dirt, and
debris. Clean and degrease the roof surface with isopropyl
alcohol and dry completely.
Figure 2 Precautions
NOTICE
GENERAL PRECAUTIONS
lDo not bend more than 30° when handling and mounting the
solar panel.
lDo not step on the solar panel's cells with hard footwear.
Failure to follow these instructions can result in physical
damage to vehicles and property.
c. For permanent mounting, apply an adhesive sealant (see TIP
1) to the solar panel's backside and place the panel on the exact
and intended location. Alternatively, install the solar panel on
the roof using appropriate screws and washers to fasten the
panel.
TIP 2: If using screws to mount the standard
flexpanel, apply a silicon outdoor UV-rated,
waterproof sealant around the screw holes
and on the screw head afterfastening to
prevent water ingressinto the roof. Contact
the vehicle/vesselmanufacturer for
recommendationson roof sealant.
NOTICE
ADDITIONAL PRECAUTIONS
lDo not mount the solar panel near other roof fixtures that can
obstruct direct exposure to sunlight.
lSelect the mounting area carefully and mark the exact and
intended location of the solar panel.
Failure to follow these instructions can result in physical
damage to vehicles and property.
d. Apply an RV roof sealant (see TIP 2) to the screw heads.

Solar Panel Maintenance and Care
Although a well designed vehicle-mounted solar system requires minimal maintenance, it is highly
recommended to perform an inspection and cleaning of the solar panels during the warranty period.
This helps to ensure optimal system performance and reliability through a few simple steps.
Visual
Inspection
Perform a visual inspection of the solar system on a monthly basis to identify if there are
any visual defects or improper connections.
nCheck for any sharp objects on the solar panel surface.
nCheck for any signs of corrosion or burnt hotspots around the solar cell and
backsheet area.
nCheck that the solar panel is clear of any shading by any foreign material or
unwanted obstacles. Just a small amount of shade on the solar panel surface can
cause significant power output loss.
nCheck that all mounting hardware is tightly screwed down per torque
recommendations.
nIf the solar panel has slight discoloration over a period of usage, this is considered
normal for solar panels that use an anti-reflection coating laminate.
Cleaning
Solar
Panels
The power output of a solar panel is proportional to the amount of sunlight that reaches
the solar cells. Therefore, any build-up of dust or dirt on the surface of the solar panel will
result in a loss of power. This is a trade-off between the maximizing the power output of
the solar panel versus the cost and time to perform regular cleaning.
cDo not clean solar panels if there is broken plastic material or exposed wiring because
this creates a risk for electric shock.
cDo not step or kneel on the solar panel during cleaning.
nCheck the solar panel periodically during seasons that the vehicle is in-use. If
there is a build-up of dust or dirt on the surface of the solar panel, it is
recommended to clean it.
nClean the solar panel in the early morning or early evening when the solar panel
is cooler, especially in hot regions. This will reduce the risk for electrical and
thermal shock.
nClean using a soft cloth together with clean water and mild detergent or soap.
lMake sure there is no soap residue remaining after cleaning.
lAvoid using water with high mineral content that may leave deposits on
the solar panel surface.
lDo not use abrasive materials to clean the solar panel.
lDo not use chemicals to clean the solar panel.
lDo not pressure wash the solar panel.

damage.
NOTE: To obtain service go to Contact Information on page 1.
Problem Possible Cause Solution
Battery does not get charged
even when sunlight is
present.
Solar panel is partially shaded
or there is insufficient sunlight.
Move the vehicle or vessel so the whole
solar panel is exposed to direct sunlight.
Loose or no DC cable
connections.
Connect DC cables to the battery and
solar panel and tighten terminal
connections.
Fuse is blown. Replace the blown fuse with a 30A/32V
green ATC blade fuse.
