要求屋顶耐火，因此需要考虑房屋结构、屋顶原材料，以及当地的相关法律法；
The installation position of the module should be consistent with therequirements of various kinds
electrical and fire code, fire rating of this module is for the C-class, when the modules are installed on
the roof, the roof needs to be fire-resistant, therefore, the designing of the housing structure, the
selection of raw material for the roof as well as the localrelevant laws and regulations need to be taken
into consideration.
若组件安装在大雪、低温、强风、水面上或近水区域（该区域极易受盐水腐蚀）、海岛、沙漠等区域，需
采取适当的步骤以保证可靠性和安全性；要保持所有电接触体干净和干燥；
Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas
such as: Heavy snow areas / extremely cold areas / Strong wind areas / Installations over, or near, water
/ Areas where installations are prone to salt water damage / Small islands or desert areas, all electrical
contacts need to be kept clean and dry.
建议组件安装在温度为
-20
℃到
46
℃的环境中，组件极限工作环境温度为
-40
℃
~85
℃；
We recommend that the modules are installed in an environment temperature from -20
℃
to 46
℃
,
the limit working environment temperature of the module is -40
℃
~ 85
℃
.

选择倾角
Tilt Angle
组件的倾角是指组件与水平地面之间所成的夹角。当组件与太阳光垂直时，组件产能最大；
The tilt angle of the PV module is the angle between the PV module and a horizontal ground surface.
The PV module generates the maximum output power when it faces the sun directly.
在北半球，组件通常应该朝向南方；而在南半球，组件通常应该朝向北方；
In the Northern Hemisphere, the PV modules should typically face south, and in the Southern
Hemisphere, the PV modules should typically face north.
对于含蓄电池的固定支架的独立光伏系统，在设计最佳安装倾角时，需要保证在阳光稀缺时系统供电充足，
若在阳光稀缺季节，系统产生的电能够满足负载要求，那么这个安装倾角也能满足其他季节的用电要求；
对于固定支架的并网系统，为了在一年内组件产出最大功率，建议组件的安装倾角等于当地的纬度值；
For the standalone systems with a battery where the PV modules are attached to a permanent structure,
the tilt angle of the PV modules should be determined to optimize the performance when the sunlight is
the scarcest. In general, if the electric power generation is adequate when the sunlight is the scarcest,
then the angle chosen should be adequate during the rest of the year. For grid-connected installations
where the PV modules are attached to a permanent structure, it is recommended to tilt the PV module at
the angle equal to the latitude of the installation site so that the power generation from the PV module
will be optimum throughout the year.
对于详细的安装角度，依据区域的不同而不同，可参考有经验的组件安装商给出的建议。
For the detailed installation angle, which is different in different area, recommendations from
experienced PV modules installation suppliers should be referred to.
