Installation Condition

Climatic Condition

1. Recommended installation a mbient 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. D uring the collection of mechanical load, it must be calculated by a professional installer according to the requirements of system design.

Installation Site Selection

In general, the PV modules should be installed in the place with the maximum sunlight throughout 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 S outh (or North direction, the power output will lose about 10% to 15%; if modules angle deviat e is 60 degrees, lose rate is about 20% to 30% of power output.

The installation site should avoid s hadows 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 f ollow the recommendations of the battery manufacturer regarding installation instructions, operation and maintenance; T o ensure that the battery is working properly, which should avoid direct sunlig ht, rain and snow erosion, mean while 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. I f 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.

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.

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 install ation angle can meet the demands of the whole year; For gridtie PV system, the installation angle selection of the modules should be based on annual power output maximization.

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:

1. Appearance Inspection
   Please kindly check the PV modules carefully, ensure the modules are without appearance faultiness. Especially pay attention to following points:

2. Double glass protector works as the protection during the transportation on, it does not belongs to appearance-controlling buyers can tear them off or save by themselves;

3. Module s glass damaged or not

4. Whether have scratches of sharp objects hit panels surface

5. Whether solar panel is blocked by obstacle and other objects or not;
   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 int o in side of laminates.

6. Checking
   whether the fixed screws are loose or damaged between modules and brackets or not, and then adjust it or repair it in time.

7. Cleaning

   • 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 soft cloth dry or damp are workable. Mineral water is not recommended for cleaning,to any dirt on glass after cleaning job.
   • 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 soft cloth dry or damp are workable. Mineral water is not recommended for cleaning,to any dirt on glass after cleaning job.
   • In order to reduce or avoid potential electric shock or burnt , DAH Solar suggest to do the clea rness during the earlier morning or dusk with lower temperature, especially in the areas with high temperature.
   • Do not try to clean the panel which has broken glass or uncovered wires.
     This may lead to the danger of electric shock.

8. Connector & Wires Inspection
   It is recommended that the following preventive mai ntenance be carried out every six months

9. Inspect the sealant gel to make sure there is no flaw or chink

10. 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.

Electrical Installation

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 :Irradianc e 1000/m2 、 Cell temperature 25℃ 、 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

Series, parallel circuit electrical diagram

The maximum number of modules per series string must be calculated according to the requirements.The value of the Voc in the local expected minimum temperature cannot exceed the maximum system voltage value specified of the module(According to IEC61730 safety test, the maximum system voltage of DAH Solar Module is DC1500V.
In Australia installations should be in accordance to AS/NZS 3000 and AS/NZS 5033.) and Other DC electrical components require values.

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(% /℃) is The temperature coefficient 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

Grounding

In design of modules, the anodized corrosion resistant aluminum alloy frame is applied for rigidity support. For safety utilization and to protect modules from lightning and static electricity damage, the module frame must be grounded.
The grounding device must be in full contact w ith inner side of the aluminum alloy and penetrate surface oxide film of the frame.
Do not drill additional grounding holes on module frame.
The grounding conductor or wire may be copper, copper alloy, or any other material acceptable for application as an electrical conductor per respective National Electrical
Codes. The grounding conductor must then make a connection to ground with a suitable ground electrode.
Holes marked with a grounding mark on the frame can only be used for grounding but not for mounting.
Frameless double glass modules have no exposed conductor, and therefore according to regulations it did not need to be grounded.
