Rated electrical characteristics of Isc, Voc, are within
±
10 percent of the indicated values.
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at Standard Test
Conditions. Accordingly, the values of Isc and Voc marked on the modules listed above should be multiplied by a factor of 1.25 when determining
component voltage ratings, conductor ampacities, fuse sizes and size of controls connected to the module output.
( for US market )
Refer to Sec. 690-8 of the National Electric Code for an additional multiplying factor of 125 percent (80 percent de-rating) which may be applicable.
Application Class
This module is rated as “Application class A” according to IEC61730.
“Application class A” means: General access, hazardous voltage,
hazardous power applications; Modules rated for use in this application
class may be used in systems operating at greater than 50V DC or 240W,
where general contact access is anticipated. Modules qualified as
“Application class A” according to IEC 61730 are considered to meet the
requirements for safety class II.
FIRE RATING
This module is rated as “Fire safety class C” according to IEC61730, and
"class E" in accordance with EN13501-1.
( for US market )
Any module mounting system has limitations on inclination required
to maintain a specific System Fire Class Rating
The fire rating of a SHARP PV module is valid only when mounted in
the manner specified in this manual.
The module is considered to be in compliance with UL1703 only
when the module is mounted in the manner specified by the
mounting instructions of this manual.
A module with exposed conductive parts is considered to be in
compliance with UL1703 only when it is electrically grounded in
accordance with the instructions presented in this manual and the
requirements of the National Electrical Code for UL listed products
only.
Any module without a frame (laminate) shall not be considered in
compliance with the requirements of UL1703 unless the module is
mounted with hardware that has been tested and evaluated with the
module under this standard or via a field inspection certifying that
the installed module complies with the requirements
of UL1703.
