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.

n

Check for any sharp objects on the solar panel surface.

n

Check for any signs of corrosion or burnt hotspots around the solar cell and
backsheet area.

n

Check 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.

n

If 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.

n

Check 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.

n

Clean 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.

n

Clean using a soft cloth together with clean water and mild detergent or soap.

l

Make sure there is no soap residue remaining after cleaning.

l

Avoid using water with high mineral content that may leave deposits on
the solar panel surface.

l

Do not use abrasive materials to clean the solar panel.

l

Do not use chemicals to clean the solar panel.

l

Do not pressure wash the solar panel.
