Please read this manual completely before installing or
using an Evergreen Solar Cedar photovoltaic (PV, solar
electric) module. This photovoltaic module produces
electricity when exposed to light. Follow all
applicable electrical safety precautions. Only
qualified personnel should install or perform
maintenance work on this module. Do not damage or
scratch the rear surface of the module. Do not handle
modules when they are wet.
S a f e t y P r e c a u t i o n s
Photovoltaic modules produce DC electricity when
exposed to light and therefore can produce an
electrical shock or burn. Modules produce voltage
even when not connected to an electrical circuit or
load. Modules produce nearly full voltage when
exposed to as little as 5% of full sunlight, and both
current and power increase with light intensity. Use
insulated tools and rubber gloves when working with
modules in sunlight.
PV modules have no on/off switch. Modules can be
rendered inoperative only by removing them from
sunlight, or by fully covering their front surface with
cloth, cardboard, or other completely opaque material,
or by working with modules face down on a smooth,
flat surface.
Modules can produce higher output than the rated
specifications. Industry standard ratings are made at
conditions of 1000 watts/m
2
and 25°C cell
temperature. Reflection from snow or water can
increase sunlight and therefore boost current and
power. In addition, colder temperatures can
substantially increase voltage and power.
Evergreen Solar modules are constructed with
tempered glass, but still must be handled with care. If
the front glass is broken or if the polymer backskin is
torn, contact with any module surface or the frame can
produce electrical shock, particularly when the module
is wet. Broken or damaged modules must be disposed
of properly.
Cedar PV modules are intended for use in terrestrial
applications only, thus excluding aerospace or
maritime conditions or use with sunlight concentration.
Excluded applications include, but are not limited to,
installations where modules are likely to come in
contact with any salt water or where likely to become
partially or wholly submerged in fresh or salt water,
examples of which include use on boats, docks and
buoys.
C o d e s a n d R e g u l a t i o n s
The mechanical and electrical installation of PV
systems should be performed in accordance with all
applicable codes, including electrical codes, building
codes, and electric utility interconnect requirements.
Such requirements may vary for mounting location,
such as building rooftop or motor vehicle applications.
Requirements may also vary with system voltage, and
for DC or AC application. Contact local authorities for
governing regulations. In the U.S., all installations
should conform to the National Electrical Code (NEC),
including Article 690 on Solar Photovoltaic Systems
and all other appropriate articles and sections.
M e c h a n i c a l I n s t a l l a t i o n
Modules may be mounted at any angle from a vertical
orientation to a horizontal one. The appropriate fixed
tilt angle and azimuth orientation should be used in
