Although the bypass diode installed in the solar photovoltaic module can reduce
this loss to some extent, do not ignore the shadow factor.
Do not install solar PV modules near fire or flammable materials. In addition to
floating projects or projects using coastal modules, do not install solar PV modules
where there is water soaking, sprinkler or water spray.
If the product needs to be used in the offshore environment *, please communicate
with Risen technical team in advance to evaluate and use the coastal modules * of
Risen.
Remarks: Offshore environment * refers to the environment within 1km of the
straight-line distance Includes on the sea surface from the coastline; Coastal
modules * can satisfy most coastal natural environments, but do not have
absoluteness. Offshore installation may have additional impact on the performance
and life of modules. If you need to install in the offshore environment, please
evaluate and confirm with Risen technical team before purchase. If the modules are
used in offshore environment projects without evaluation,Risen shall not be
responsible for the failure of the modules due to environmental factors
7.2. Tilt angle of Installation
The installation of solar PV module string should be in the same orientation and the
same installation angle. Different installation directions and installation angles will
lead to the mismatches in current and voltage which is caused by different light
absorption of different solar modules, this mismatch will cause the PV system
power output loss.
The largest power will be generated When direct sunlight on solar PV module. For
modules which are installed on the fixed brackets, the best installation angle
should be selected to ensure the maximum power output can be generated at
winter time, if the angle can guarantee enough power output during the winter, it
will make the whole solar PV system in the rest of the year can have enough power
output also.
