Important! Please read this instruction sheet in its
entirety before installing, wiring, or using this
product in any way. Failure to comply with these
instructions will invalidate the SunPower Limited
Warranty for PV Modules.
1.1 Disclaimer of Liability
The installation techniques, handling and use of this product
are beyond company control. Therefore, SunPower does not
assume responsibility for loss, damage or expense resulting
from improper installation, handling or use.
1.2 International Electrotechnical Commission (IEC) Listing
Information
This product meets or exceeds the requirements set forth by
IEC 61215 Edition 2 for PV Modules, as well as IEC 61730 for
Class A applications. The IEC Standard covers flat-plate PV
modules intended for installation on buildings and those
intended to be freestanding. This product is not intended for
use where artificially concentrated sunlight is applied to the
module.
1.3 Limited Warranty
Module limited warranties are described in the SunPower
warranty certificates obtainable at www.sunpowercorp.com.
Warranties do not apply to any of the following;
PV modules which in SunPower's absolute judgment have
been subjected to: misuse, abuse, neglect or accident;
alteration, improper installation, application or removal
(including but not limited to installation, application or
removal by any party other than a qualified personnel; non-
observance of SunPower's installation, users and/or
maintenance instructions; repair or modifications by
someone other than an approved service technician;
power failure surges, lightning, flood, fire, accidental
breakage or other events outside SunPower's control.

Safety Precautions

Before installing this device, read all safety instructions in this
manual.
Danger! Module interconnects pass direct current (DC)
and are sources of voltage when the module is under load
and when it is exposed to light. Direct current can arc
across gaps and may cause injury or death if improper
connection or disconnection is made, or if contact is
made with module components that are damaged. Do
not connect or disconnect modules when current from the
modules or an external source is present.
Cover all modules in the PV array with an opaque cloth or
material before making or breaking electrical connections.
It is imperative to use the supplied locking connectors and
safety clips in order to defend against untrained personnel
disconnecting the modules once they have been installed.
All installations must be perfo
applicable regional and local codes.
There are no user serviceable parts within the module. Do
not attempt to repair any part of the module.
Installation should be performed only by qualified personnel.
Remove all metallic jewelry prior to installing this product to
reduce the chance of accidental exposure to live circuits.
Use insulated tools to reduce your risk of electric shock.
Do not stand on, drop, scratch or allow objects to fall on
modules.
Damaged modules (broken glass, torn back sheet, broken j-
boxes, broken connectors, etc) can be electrical hazards as
well as laceration hazards. Contact with damaged module
surfaces or module frame can cause electric shock. The
dealer or installers should remove the module from array
and contact the supplier for disposal instructions.
Do not install or handle the modules when they are wet or
during periods of high wind.
Contact your module supplier if maintenance is necessary.
Save these instructions!

Electrical Characteristics

The module electrical ratings are measured under Standard
Test Conditions (STC) of 1 kW/m² irradiance with AM 1.5
spectrum and a cell temperature of 25º C. SunPower modules
have specific electrical characteristics as shown on the
datasheets.
Bypass diodes for each module are factory installed in the
modules. The diodes have one of the following ratings;
1. 8A, 45 PIV (Peak Inverse Voltage) for 72 & 96 cell
modules.
2. 12A, 200 PIV (Peak Inverse Voltage) for 128 cell
modules.
A photovoltaic module may produce more current and/or
voltage than reported at STC. Sunny, cool weather and
reflection from snow or water can increase current and power
output. Therefore, the values of I
module should be multiplied by a factor of 1.25 when
determining component voltage ratings, conductor ampacities,
fuse sizes, and size of controls connected to PV output. An
additional 1.25 multiplier may be required by certain codes for
sizing fuses and conductors.
SunPower recommends the use of open-circuit voltage
temperature coefficients listed on the datasheets when
determining Maximum System Voltage.
