Purpose of this guide
This guide contains information regarding
the installation and safe handling of
Shell Solar photovoltaic modules (hereafter
referred to as “modules“).
Please follow these instructions carefully
and observe all of the safety precautions.
Although this guide describes several typi-
cal systems using photovoltaic solar power
modules, it
does not
describe how to install
or operate such systems. Please consult your
solar power dealer for additional information
on the following subjects:
}
dimensioning and constructing solar pho-
tovoltaic systems
}
wiring materials
}
connectors
}
stands and supports
Before installing a solar photovoltaic system,
you should familiarize yourself with the
mechanical and electrical requirements for
such systems. For this reason, we recommend
that you read this guide completely before
starting the installation.
In the guide, the term ‘module’ should gener-
ally be understood to refer to individual
modules and/or groups of modules accord-
ing to the context.
Caution
If these products are used in the
USA, please observe the instruc-
tions marked ‘[USA]’.
General information
Installing solar photovoltaic systems may
require specialised skills and knowledge.
It should only be performed by qualified
electricians.
Caution
If the total DC voltage available
from several modules connected
in series (the sum of the open-cir-
cuit voltages of the individual modules) can
exceed 120 V, installation and commission-
ing of the system must be performed by a
licensed electrician or specialized company.
The installer assumes the risk of all injury that
might occur during installation, including,
without limitation, the risk of electric shock.
Shell Solar electric modules do not require
the use of special cable assemblies. All mod-
ules come with a permanently attached junc-
tion box that will accept a variety of wiring
applications or with a special cable assembly
for ease of installation. It is recommended
to utilize a qualified installer or reseller for
service.
WARNING
All instructions should be read
and understood before attempt-
ing to install, wire, operate, and
maintain the module. Contact with electrically
active parts of the module such as terminals
can result in burns, sparks, and lethal shock
whether the module is connected or discon-
nected.
Proper use
Photovoltaic solar modules produce direct-
current electrical energy from light. They are
designed for outdoor use, and depending on
their construction can be mounted on support
frames, stands, flat surfaces, vehicles or boats.
}
Do not
disassemble the module, and do
not remove any attached nameplates or
components.
}
Do not
apply paint or adhesive to the rear
surface.
}
Do not
use mirrors or lenses to artificially
concentrate sunlight on the module.
