supplied with the module and evaluated through the requirements in UL 1703, may be
used for grounding connections in accordance with the instructions provided with the
module.
Under normal conditions, a photovoltaic module is likely to experience conditions that
produce more current and/or voltage than reported at standard test conditions. The
requirements of the National Electrical Code (NEC) in Article 690 shall be followed to
address these increased outputs. In installations, not under the requirements of the NEC,
the value of Isc and Voc marked on the module should be multiplied by a factor of 1.25
when determining component voltage ratings, conductor ampacities, overcurrent device
ratings, and size of controls connected to the PV output.
Once the PV module has been shipped to the installation site, all of the parts should be
unpacked properly with care.
Do not stand or step on the PV module like below pictures show. This is prohibited and
there is a risk of damage to the module and cause injury for you.
Only PV modules with the same cell size should be connected in series.
During transporting modules, please attempt to minimize shock or vibration to the module,
as this may damage the module or lead to cell micro cracks.
During all transportation situations, never drop the module from a vehicle, house or
hands. This will damage the module.
Do not clean the glass with chemicals. Only use tap water. Make sure the module surface
temperature is cool to the touch. Cleaning modules with cool water when module surface
temp is high may result in glass breakage.
Do not disconnect any of the modules when under load.
The recommended standoff height is
6 inches (
15cm
)
. If other mounting means are
employed this
may affect the UL Listing.
When looking at PV modules with anti-reflection (AR) coating technology, it will be normal
to see some cells with a slight color difference at different angles.
Modules with LRF
(light reflective film) and without LRF should not be built in the same array.
Do not use modules in an environment with aliphatic, aromatic, phenols, ketones,
halogenated substance or mineral oil, which may corrode the junction box by chemical
attack.
