2.2 Installation Condition
2.2.1 Climatic Condition
1) Recommended installation ambient temperature is between -40°C to 85°C (-4°F to 185°F).
2) Do not install PV modules in a flooded risk area.
Note: The PV module mechanical load (including the wind and snow pressure) is based on the installation method and installation
site. During the collection of mechanical load, it must be calculated by a professional installer according to the requirements of
system design.
2.2.2 Installation Site Selection
In general, the PV modules should be installed in the place with the maximum sunlight thoughout the year.In the northern
hemisphere, modules should be placed toward south as the first choice, while in the southern hemisphere, it should be
placed toward north. If the angle of the modules deviate 30 angle away from the South (or North) direction, the power
output will lose about 10% to 15%, if modules angle deviate is 60 degrees, lose rate is about 20% to 30% of power output.
The installation site should avoid shadows of tree, building and other obstacles. Module manufacturer have already
installed the bypass diode to minimize the loss, but the shadow will still reduced output power.
When the PV system equipped with batteries bank, it must be installed correctly, which can protect the system operation
and ensure the safety of user during their using. Please follow the recommendations of the battery manufacturer
regarding installation instructions, operation and maintenance. To ensure that the battery is working properly, which
should avoid direct sunlight, rain and snow erosion, meanwhile maintaining good ventilation. Most kinds of battery
charging could release hydrogen which explosion easily happen. It must avoid a fire or make a spark around the batteries
bank. If the battery installed outdoors, which must the placed in a specially designed area with insulation and ventilation.
Do not install the PV modules close the naked light or flammable materials.
Do not install the PV modules in places where it would be immersed in water or continually exposed to water from a
sprinkler or fountain etc.
If connect to the independent PV system, modules angle should be based on season and sunshine condition to obtain
the maximum power output. Normally, if module’s power output could be satisfied during the lowest sunshine intensity
of a year, then this installation angle can meet the demands of the whole year. For grid tie PV system, the installation
angle selection of the modules should be based on annual power output maximization.

2.2.3 Angle Selection
The angle of the PV modules refers to the angle between module surface and the ground (Figure 1), the output power
will be maximum when modules are facing the sun in vertical.

3. Wiring and connection
a) Before the installation, please read carefully the operation instructions of PV system. Using multi-connecting cables to
make the PV modules in series or parallels, which is determined by the customers’ requirements on the solar system power,
current, voltage etc.
b) Please connect similar current level modules for series connection, and output voltage should not be higher than
permitted system maximum voltage. Module number of each series depends on the system design, inverter type and the
installation environment.
c) The max rated fuse current of each series is marked on the label of each module and also in the specification sheet. The
rated fuse current refers to the highest reverse current that each module can bear. Based on the max fuse current and
installation requirements of the local electrical performance, please match and choose the suitable fuse to protect the PV
modules in series or parallels.
d) Opening the connector of control system and connect the cables from the PV arrays to the connector in accordance with
the installation indication of the PV control systems. The cross-sectional area and cable connector capacity must satisfy the
maximum short-circuit of PV system (For a single component, we recommended the cross-sectional area of cables is 4mm
and the rated current of connectors is more than 10A), otherwise the connecting cables and connectors will be over heating.
Please pay attention that the temperature limit of the cables is 85°C.
e) The electrical connections must be properly in accordance with local and national electrical rules.
f) All PV modules are included with the bypass diodes. Please notice that the diodes, cables and junction boxes maybe
damaged caused by the wrong installation.
4. Maintenance
PV modules need to be inspected and maintenance regularly, especially during the warranty period. In order to make
sure modules reaching the excellent performance, DAH Solar adopts following maintenance measures:
4.1 Appearance Inspection
Please kindly check the PV modules carefully, ensure the modules are without appearance faultiness. Especially pay
attention to following points:
a) Double glass protector works as the protection during the transportation, it does not belongs to appearance
controlling , buyers can tear them o or save by themselves.
b) Module’s glass damaged or not.
c) Whether have scratches of sharp objects hit panels surface.
d) Whether solar panel is blocked by obstacle and other objects or not.
e) Whether have corrosion near grid finger of solar cell. This is caused by the damage of laminates surface during the
installation or transportation, steam filter into inside of laminates.
f) Checking whether the fixed screws are loose or damaged between modules and brackets or not, and then adjust it or
repair it in time.

4.2 Cleaning
a) Dust or dirt on the modules glass will decrease power output. Clean modules preferably once per year if possible (depend
on site conditions) . Using a so cloth dry or damp are workable. Mineral water is not recommended for cleaning, to any dirt
on glass aer cleaning job.
b) Never use abrasive material to do the clearness under any circumstances.
c) In order to reduce or avoid potential electric shock or burnt, DAH Solar suggest to do the clearness during the earlier
morning or dusk with lower temperature, especially in the areas with high temperature.
d) Do not try to clean the panel which has broken glass or uncovered wires. This may lead to the danger of electric shock.
4.3 Connector & Wires Inspection
It is recommended that the following preventive maintenance be carried out every six months.
a) Inspect the sealant gel to make sure there is no flaw or chink.
b) Inspect whether have aging phenomenon of modules.Includes potential broken caused by the bites of rodent, climate
aging, and all the connectors are connected tighten, have corrosion phenomenon or not. Inspect the grounding connection
in good condition or not.
5. Electrical Installation
Series Connection Parallel Connection
Electrical performance parameter of module, such as nominal value of Isc、Voc and Pmas has ±3% random error
compared with value of STC. The standard Testing Environment of module is: Irradiance 1000/m2、Cell temperature
25°C、Spectrum AM 1.5.
Normally, the current and voltage of module, will be a little higher compared with the value under STC, so when
confirmed the associated parameters of solar system accessories, such as rated voltage、cable capacity、fuse capacity
and module power, the corresponding short circuit current and open circuit voltage should be amplified by 1.25 times.
The Voc correction factor can be calculated according to the following formula: CVoc=1- βVoc×(25-T), T is The minimum
ambient temperature expected for the installation of the system, β(% /°C) is The temperature coeicient of the selected
module Voc (According to the corresponding Module Data sheet).
If the reverse current which probably exceed the maximum fuses current of module passed through the module, the
modules must be protected by an equivalent current protection device. If the number of parallel is more than or equal to
2 strings, there must be equipped an over current protection device on each series of modules.
