System Installation Conditions

Climate Condition
Install the PV module in the following conditions:
Environment temperature: -20℃ to 40℃.
Operating temperature:-20℃ to 80℃.

Don’t dip the modules in the water or exposure in the fountain.
Module should be exposed to direct sunlight rather than indirect.

Away from salt-erosion and vulcanized areas.
High temperature will reduce the performance of components,lower power output. Good ventilation can effectively prevent overheating photovoltaic components.

Do not install the PV module near the shadow, even though the factory fitted bypass diodes of the PV module will minimize any such loss. Shading causes loss of output.
Do not install module on smooth roof.
Do not install module near flammable gases.
Do not drop or allow objects to fall onto module. Do not drill holes in frame.

Installation Position
The solar module should be installed in a position that allows the maximum sunlight to fall on it for the entire day. For maximum performance, face the solar panel towards the equator(north in the southern hemisphere, south in the northern hemisphere), and title at an angle depending on latitude. This allows maximum exposure to both the winter and summer sun.

The angle of the face regardless should always be titled slightly to allow rainwater to wash accumulated dust off the glass face. If the panel is to be used on a motor vehicle or ship, mount the panel horizontally to enable optimum sunlight regardless of vehicle positioning

System Maintenance  
Please don’t change modules’ accessories(diodes、junction box、cable tie-in and so on), if damaging,
please replace the same types, or inquiry manufacturer.

There is no need to clean if the modules have pitch (at least 15º). Rainwater has the ability of cleaning.
We recommend rinse the surface of modules if its pollution affected the output of modules.
It can’t be cleaned when dirt is drying. We suggest regular examination after the photovoltaic system installed.

Protect the cables against mechanical stress when they are being laid (e.g. against pressure from being trodden on).

It is a good idea to have the PV system inspected by an electrician at the same intervals as the general electrical system of the house.

If a mechanical defect is identified in a PV panel (e.g. if the glass in the front panel is broken by a forceful impact), this element must be changed and replaced by a new one (see section on “Changing panels”).

Cleaning the battery terminals. Do not use any metal files or other harsh abrasives (e.g. sand paper) to remove corrosion or oxidization from terminals or posts as this may cause a poor fit when terminals are reconnected.

Do not use chemicals on solar modules when cleaning.

Please check the charge controller every 2 months. If there is something wrong, look up the user manual of charge controller.
