Mechanical properties / electrical properties
The rated electrical performance data of the module were
measured under standard test conditions (STC) at irradiance
of 1 kW / m2, AM1.5, cell temperature of 25 ° C. Appendix A
of this installation manual contains specific electrical
specifications for Photonic Universe solar modules. The
nameplate of each component is also marked with the main
electrical properties under STC conditions.
In some cases, the current or voltage generated by the
component may be
Can be greater than its standard test environment (STC) the
best working current or voltage. When determining
component ratings and load values, the component open
circuit voltage and short circuit current at STC should be
multiplied by 1.25. When determining the appropriate
conductor and fuse size, the short-circuit current must be
multiplied by 1.25 in accordance with local regulations, and
the open-circuit voltage multiplied by the correction factor.

Storage and unpacking
Precautionary measures and general safety rules
·The components should be stored in a dry and ventilated
environment.
The components must be shipped in the box supplied with
the Photonic Universe and stored in the original box before
installation. Please protect the packaging not to
Damaged. Unpack the components in the recommended
unpacking steps. Open the packaging,
Transport and storage should be handled with care.
·
Do not apply excessive load or twist to components.
• Do not carry the components through the wires or junction
boxes of the unit
Shall be carried by two or more persons holding the
components.
•
The overhead assembly is prohibited.
• Do not stack components.
• Do not drop or stack items (such as mounting tools) on the
unit.
• Do not grasp the terminal block or the cable to lift the entire
assembly.
Before installing the PV modules, check whether the
components are damaged during transport and do not install
damaged PV modules. If you find damaged PV modules,
contact Photonic Universe to obtain the information you need
to complain about defective PV modules.
The PV module's surface is vulnerable, and damaged PV
modules may affect its performance and safety; do not
damage or scratch the surface of PV modules. For your
safety, do not disassemble or modify the components in any
way that may affect the performance and safety of the
components, even cause irreparable damage, and void any
trial warranties.

Component Installation
Do not install components near flames or combustible
objects.
•Do not immerse the components in water (pure water
or salt water) or long-term water (pure water or salt
water) (such as fountains, spray, etc.).
•
Ensure that the components meet the overall technical
requirements of the system.
Allow the series components to increase the voltage or
increase the current in parallel. In series, the positive
terminal of the module is connected to the next
negative terminal. When connected in parallel, the
positive terminal of the module is connected to the
positive terminal of the next module.
•The number of bypass diodes provided will vary
depending on the model of the component.
•Up to two strings of components can be connected in
parallel without using an overcurrent protector (fuse) in
series with each string. Three strings or more can be
connected in parallel, provided that an appropriately
validated overcurrent protection is connected in series
with each string.
Avoid shadows
• Even small shadows (eg dust, bird droppings, branches)
can cause a drop in power generation. If all surfaces are
unobstructed throughout the year, the component is
considered "shadowless." To ensure that even in the shortest
day of sunshine throughout the year, the sun can still shine
on the components. When the components are installed in
the car, parking should avoid buildings, trees and other
shade of the block.
• Frequent blockage of components can result in aging of the
EVA and persistent heating of the cell sheet, which may
result in damage to the components and can not be used.
