3.1Routine Safety
Solglass's module design complies with international IEC 61215 and IEC 61730 standards, and its
application rating is Class A: The module can be used for systems with voltage higher than 50V or
240W DC. And the module has passed IEC 61730-1 and IEC 61730-2, the module meets the
requirements of Class II.
The overall fire rating of the final structure needs to be considered when the module is installed for
use on the roof. At the same time, the overall maintenance is also needed to be considered. Rooftop
PV systems can only be installed after an evaluation by a construction expert or engineer, with formal,
complete structural analysis, and proven to be able to withstand additional system support pressure,
including the pv module's own weight.
For your safety, please do not work on the roof without safety precautions including but not limited to
fall protection, ladders or stairs and personal protective equipment.
For your safety, do not install or handle modules under bad conditions, including but not limited the
high winds or gusts, wet or sandy roofs.
3.2 Electrical Safety
PV products generate direct current in the presence of sunlight, so touching the the wire metal of the
module can be a risk of electric shock or burn. A 30 volt DC or higher voltage can be fatal.
The module also generates voltage without connecting the loads or external circuit. Use an insulated
tool and wear rubber gloves when operating module in the sunlight.
There's no switch on the pv module. The PV module can only be stopped by removing it from the
light or by shielding it with cloth, cardboard, or a completely opaque material, or by placing the front
side of the module on a smooth, flat surface.
In order to avoid the danger of electric arc and electric shock, do not disconnect the electrical
connection under the load. The wrong connection can also cause arcing and electric shocks.
Connectors must be kept dry and clean to ensure that they are in good working condition. Do not
insert a metal object into the connector, or otherwise make an electrical connection.
The power generated by the module may be higher than the nominal rating on the name plate. The
rated output power of the factory test calibration is measured under the module standard test
conditions (module standard test conditions: 1000 W / M2 irradiance, 25 °C ambient temperature,

5
AM1.5 atmospheric mass) . The surrounding snow and water reflect more light, causing an increase
in current and output power.
In addition, at low temperature, the voltage and power of the module will increase correspondingly.
If the module glass or other material damage, please wear a personal protective device, separate
the component from the circuit.
Do not touch the module if it is wet. Except when cleaning components, but in accordance with the
requirements of the manual cleaning components.
Never touch a wet connector without wearing a personal protective device or rubber gloves.
Do not use a mirror or magnifying glass to manually focus the sunlight on the module.

Installation steps
6. Electrical installation
6.1 Electrical property
There is a tolerance between the nominal values of modules such as Isc, Voc and Pmax
under standard test conditions, perhaps the value is relatively higher compare to the value
obtained under component standard test conditions. Therefore, in the determination of
photovoltaic system accessories, such as rated voltage, wire capacity, fuse capacity and
module power output and related parameters, the relating short current and open voltage
amplify 1.25 times can be applied.

Under normal conditions, a photovoltaic module is likely to experience conditions that produce
higher current and/or voltage than reported at standard test conditions. Accordingly, the values
of Isc and Voc. marked on this PV module should be multiplied by a factor of 1,25 when
determining component voltage ratings, conductor current ratings, and size of controls (e.g.
inverter) connected to the PV output.

The maximum number of components that can be connected in series must be calculated in
accordance with the requirements of the relevant regulations, the open-circuit voltage shall not
exceed the maximum system voltage value specified by the component (According to the safety
test of IEC 61730, the maximum system voltage of the SOLGLASS’s modules is DC1000V)
If reverse current may flow through the module exceeding the maximum fuse current of the
module, the module shall be protected by overcurrent protecting device that it has the same
specification. If the number of parallel connections is more than or equal to 2 strings, there must
be an overcurrent protection device on each string.
6.2 cable and connecting
In the design of cables and connections, assemblies, field connections use sealed junction
boxes of Class IP67 to provide protection against environmental impacts for conductors and
their corresponding connections, and to provide touchable protection for uninsulated parts. The
junction box has well-connected cables, wires and protective Class IP67 connectors. These
designs are convenient for connecting modules in series. Each module has two wires
individually connected to the junction box, one positive and one negative. The two modules can
be connected in series by inserting a positive terminal at the other end of a module wire into the
socket of the negative terminal of an adjacent component.
Field connection cables must meet the component's maximum short circuit current usage, and
SOLGLASS recommends that installers use only light resistant cables that meet PV DC
requirements in PV systems, with a minimum diameter of 4mm².

When the cable is fixed to the bracket, it is necessary to avoid mechanical damage to the cable
or module. Do not apply pressure to the cable. For cables that are secured in the proper way,
installer must use special light-resistant cable, wires and wire clips to fix the cable to the bracket.
Although the cable is light and water resistant, avoid direct sunlight and water immersion.
6.3 Connecting
Please keep the connector dry and clean. Make sure the connector nut is in a tight status before
connecting. Do not connect connectors when the connector is wet, soiled, or otherwise. Avoid
direct sunlight and immersion of connectors in water. Avoid connector landing on the ground or
roof.
The wrong connection could create an electrical arc and shock. Please check that all electrical
connections are reliable. Make sure all the connectors with locks are fully locked.

6.4 The bypass diode
Recommended diode：20SQ045 of Zhejiang Zhonghuan Sunter PV Technology Co.,Ltd.
SOLGLASS's solar module junction box contains the bypass diode and is parallel connected to
the cells string inside the module. When the hot spot occurs locally, the diode will pass only
current through the non-hot spot cell, limiting the module's heat and performance loss. Note that
the bypass diode is not an over current protection.
When you know or suspect a diode failure, contact SOLGLASS for installation or system
maintenance. Please do not attempt to open the junction box of the module.
7. Operation and Maintenance
The modules must be inspected and maintained regularly, especially during the warranty period,
which is the responsibility of the user and notify supplier within two weeks if any module is found
to be damaged.
Dust, such as industrial waste water and, bird droppings, deposits on the glass surface of the
module reduces its power output and may cause regional hot spots. The extent of the effect
depends on the transparency of the waste, and the small amount of dust on the glass affects
absorbing the intensity and uniformity of sunlight, but is not dangerous, and the power is usually
not significantly reduced.
There must be no environmental impact factors, such as the presence of other modules, module
system bracket, bird presence, large amounts of dust, soil, or vegetation that cast a shadow over
the modules and obscure some modules or all modules while they are in operation, resulting in a
significant reduction of output power. SOLGLASS recommends that the surface of the
component not be obscured at all times.
As for the frequency of cleaning, it depends on the dirt accumulates level . Under normal
circumstances, rainwater would clean the surface of the modules, which would reduce the
frequency of cleaning. SOLGLASS recommends using a damp, water soaked sponge or a soft
cloth to clean the glass and surface. Do not use detergent containing alkali or acid to clean
modules.

14
7.1 Visual inspection of modules
Visual inspection of the modules of the appearance of defects, especially
1, the module glass broken.
2. Corrosion of the welding at the main busbar of the cell : Due to during installation or
transportation, the insulating material is damaged, causing moisture entering into the module.
3. Checking the module if any burn marks inside.
7.2 Inspection of connectors and cables
It is recommended that preventive inspections be carried out every six months, as follows:
1. Check the tightness of the connectors and make sure whether the cable connection is secure.
2. Check the junction box to see if the sealant is cracked or has gaps.
8. Others
External or otherwise artificially concentrated sunlight shall not be directed onto the front or
back face of the PV module.
Meaning of crossed –out wheeled dustbin:
Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities. Contact your local government for information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into
the groundwater and get into the food chain, damaging your health and well- being. When
replacing old appliances with new ones, the retailer is legally obligated to take back your old
appliance for disposals at least free of charge.
9. Ground/earth the modules
Our modules don’t need to be grounded, but the metal brackets (if use) which support the
modules must be grounded.
