Mechanical / Electrical Specifications; Unpacking And Storage - CanadianSolar CS1V-MS Series Installation Manual

Do not allow children or unauthorized
persons near the installation site or
module storage area.
Do not install modules in strong wind.

 Use electrically insulated tools to reduce the risk of
electric shock.
 If the disconnects and over current protection devices
(OCPDs) cannot be opened or the inverter cannot be
powered down, cover the fronts of the modules in the
PV array with an opaque material to stop the
production of electricity when installing or working on
a module or wiring.
Do not use or install damaged modules.

 Contact with module surfaces or frames may cause
electric shock if the front glass is broken or the
backsheet is torn.
 The PV module does not contain any serviceable parts.
Do not attempt to repair any part of the module.
 Keep the junction box cover closed at all times.
Do not disassemble a module or remove any module

part.
Do not artificially concentrate sunlight on a module.

Do not connect or disconnect modules when current

from the modules or an external source is present.
3.0 MECHANICAL / ELECTRICAL
SPECIFICATIONS
Module electrical ratings are measured under Standard
Test Conditions (STC) of 1000 W/m
AM1.5 spectrum, and a cell temperature of 25°C. Detailed
electrical and mechanical characteristics of Canadian
Solar crystalline silicon PV modules can be found in Annex
A (Module Specifications) on www.csisolar.com. Main
electrical characteristics at STC are also stated on each
module label. Please refer to the datasheet or the product
nameplate for the maximum system voltage.
Under certain conditions, a module may produce more
current or voltage than its Standard Test Conditions rated
power. As a result, the module short-circuit current under
STC should be multiplied by 1.25, and a correction factor

2 irradiance, with an
should be applied to the open-circuit voltage (see Table 1
below), when determining component ratings and
capacities. Depending on your local regulations, an
additional 1.25 multiplier for the short-circuit current
(giving a total multiplier of 1.56) may be applicable when
sizing conductors and fuses.

circuit voltage

Temperature (°C/°F)
24 to 20 / 76 to 68
19 to 15 / 67 to 59
14 to 10 / 58 to 50
9 to 5 / 49 to 41
4 to 0 / 40 to 32
-1 to -5 / 31 to 23
-6 to -10 / 22 to 14
-11 to -15 / 13 to 5
-16 to -20 / 4 to -4
-21 to -25 / -5 to -13
-26 to -30 / -14 to -22
-31 to -35 / -23 to -31
-36 to -40 / -32 to -40
Alternatively, a more accurate correction factor for the
open-circuit voltage can be calculated using the following
formula:
�� = �� − ��
Voc
T (°C) is the lowest expected ambient temperature at the
system installation site.
α (%/°C) is the voltage temperature coefficient of the
Voc
selected module (refer to corresponding datasheet).
Electrical calculations and design must be performed by a
competent engineer or consultant.

optimization and approval of project specific module
string lengths.
