the installation ground where are more lightning strike.
系统设计需要有防雷击功能，特别是在安装地有较多雷击，一定要更加重视。
When installing Solar modules on a roof, the roof must be covered with a layer of fireproof material
applicable to this class, and adequate ventilation must be ensured between the back of the module and the
installation surface. A safe working area also must be left between the edge of the roof and the external edge of
the Solar array.
当在屋顶上安装太阳能组件时，屋顶上必须要覆盖有一层适用于该等级的防火材料，并且保证组件背面和安装
面之间充分的通风，要在屋顶边缘和太阳能阵列的外边缘之间留出安全的工作区域。
In the case of residential installations on the ground, modules must be installed following local regulations,
e.g. using fence.
如果住宅设施在地面上，组件的安装应按照当地法规进行，例如安装中需要用到围栏。
Sunpro Power Modules can be mounted in landscape and portrait orientation however the impact of dirt
shading the solar cells can be minimized by orienting the product in portrait.
Sunpro Power 组件可以横向和纵向安装，但是通过纵向放置产品可以最大限度地减少灰尘遮蔽太阳能电池的
影响。
Avoid using a mounting method that will block the drainage holes in the module frame.
避免使用会堵塞模块框架排水孔的安装方法。
5.3、TILT ANGLE OF INSTALLATION 光伏组件安装倾角
The installation of Solar PV module string should be in the same orientation and the same installation angle.
Different installation directions and installation angles will lead to the mismatches in current and voltage which is
caused by different light absorption of different Solar modules, this mismatch will cause the PV system power
output loss.
太阳能光伏组件串的安装应该保持同一方位和同一安装角度。不同的安装方位和安装倾角会导致不同的太阳能
光伏组件串吸收光线总量存在差异而导致的产生的电流和电压不匹配，从而降低系统运行效率，造成功率输出损失。
When all solar modules are mounted in the same plane and orientation then all can be expected to have
similar performance throughout the day and can be connected together to the same inverter channel.
当所有太阳能组件安装在同一平面和方向上时，所有组件都有望在全天具有相似的性能，并且可以连接到同一
个逆变器通道。
If solar modules on the same installation are mounted at different angles or orientations then energy
production can normally be optimized by connecting the different orientations to different inverters (or different
MPPT if the inverter has more than one MPPT). Refer to inverter manufacturers for further guidelines.
如果同一装置上的太阳能组件以不同的角度或方向安装，通常可以通过将不同的方向连接到不同的逆变器（如
果逆变器有多个 MPPT，则连接不同的 MPPT）来优化能源生产。 请参阅逆变器制造商了解更多指南。
The largest power will be generated When direct sunlight on Solar PV module. For modules which are
installed on the fixed brackets, the best installation angle should be selected to ensure the maximum power output
can be generated at winter time, if the angle can guarantee enough power output during the winter, it will make
the whole Solar PV system in the rest of the year can have enough power output also.
当阳光直射到太阳能光伏组件上时产生的功率最大，对于那些安装在固定支架上的太阳能光伏组件，选择最佳
的安装倾角时应考虑冬季的太阳能光伏组件的功率产出，如果该角度能保证光伏组件在冬季有足够的功率输出，那
将会使整个太阳能光伏组件体系在一年中的余下时间里也能有足够的功率产出。
Solar modules are recommended to be installed at an optimized tilt angle to maximize the energy output.
For detailed information on the best installation angle, please refer to standard Solar photovoltaic installation
