五、安装太阳能光伏系统的安全防范
SAFE PRECAUTIONS FOR INSTALLING SOLAR PHOTOVOLTAIC SYSTEMS
阳光照射组件正面时，太阳能电池组件产生直流电能且直流电压可能超过 30V。如果组件串
联，总电压等于单个组件电压总和；如果组件并联，则总电流等于单个组件电流总和。
When sunlight shines the front of the module, the solar cell module generates direct current
power and the DC voltage may exceed 30V. If the modules are in series, the total voltage is equal
to the sum of the individual module voltages; If the modules are connected in parallel, the total
current equals the sum of the currents of the individual modules.
在运输和安装组件时，应使儿童远离组件。
Keep children away from modules when transporting and installing them.
在安装过程中用不透明材料完全覆盖组件以防止电流产生。
Completely cover modules with opaque material during installation to prevent electricity
from being generated.
安装或维护光伏系统时，不要穿戴金属戒指、手表、耳环或其它的金属配饰，禁止利器与组
件玻璃表面接触。
When installing or maintaining a PHOTOVOLTAIC system, you don't wear metal rings,
watches, earrings or other metal accessories, and prevent sharp objects from coming into contact
with the module's glass surface.

光伏组件安装手册

件的电性能参数如 Isc，Voc 和 Pmax 与标称值有一定的偏差。
At standard test conditions (irradiance:1000W /m2 , AM1.5 spectrum, and ambient
temperature of 25 °C (77 °F)), the module's electrical parameters such as Isc, Voc, and Pmax
deviate somewhat from the nominal values.
在普通室外条件下，组件产生的电流和电压与参数表中列出的有所不同。参数表是在标准测
试条件下测得，所以在确定光伏发电系统中其它部件的额定电压、导线容量、保险丝容量、
控制器容量等和部件功率输出有关联的参数时，参照标在组件上的短路电流和开路电压的值，

The modules shall be installed in a position where full sunlight is available and shall not be
covered at all times.
不要把组件放置在易产生或聚集可燃气体的地方。
Do not place modules where combustible gases are likely to be generated or collected.
7.2 选择合适的支架 Choose the right bracket
必须遵守支架所附的说明书指导和安全守则。
you have to adhere to the instructions and safety rules that come with the stand.
不要在组件玻璃的表面钻孔，以防对组件造成破坏，从而使保修失效。

光伏组件安装手册

Anyway, don't drill holes into the surface of a module's glass, in case you damage the
module and void your warranty.
不要在组件的边框上钻附加的安装孔，否则保修失效。
Anyway, don't drill additional mounting holes in the bezel of a module, otherwise your
warranty lapses.
光伏组件采用压块固定安装方式时：压块不得压住组件正面玻璃且不能脱离边框。确保压块
不会导致盖住组件的阴影。请确保在任何环境下未对边框做改造。当选择压块安装方式时，
请确保至少有 4 个/8 个压块固定在长边框上（如下图）。取决于当地的载荷情况，如果预期
有超出设计载荷的情况时，应当增加额外的压块或者支撑材料。当固定压块时，应当提供足
够强度的固定扭矩（特殊设计请咨询压块供应商）以便保证压块的可靠。
When the photovoltaic module is fixed by pressing block, the pressing block shall not press
the front glass of the module and shall not break away from the frame. Ensure that the lumps do
not cause shadows that cover the modules. Make sure you do not change the frame in any
environment. When selecting the mounting method of the pressing block, ensure that at least 4 or
8 pressing blocks are fixed on the long frame (as shown below). Depending on the local load
conditions, additional blocks or support materials should be added if the design load is expected
to exceed it. When the block is fixed, a fixed torque of sufficient strength should be provided
(consult the block supplier for special designs) to ensure the block is reliable.

当在支柱上安装组件时，请选择能够承受当地预期风力的支柱和组件安装结构。
When installing modules on struts, select a strut and module installation structure that can
withstand the expected local wind force.
7.6 机械安装通则 General rules for mechanical installation
使用安装孔安装时：
Installing using a mounting hole
标准情况下，使用组件边框上内侧的 4 个对称安装孔来安装组件。
A module is installed automatically using four symmetrical mounting holes on the inside of
the module's bezel.
如果当地有强风或大雪，同时使用外侧的 4 个对称的安装孔。
Use four symmetrical mounting holes on the outside simultaneously if there is strong wind
or snow in the area.
不要利用组件的接线盒或电缆头来移动组件。
Don't move a module using its junction box or cable head.
不要站在或踩在组件上。
Anyway, don't stand or step on modules.
不要使组件掉落或让物体落在组件上。

光伏组件安装手册
18
Do not drop modules or let objects fall on them.
为了避免组件玻璃破碎，不要在组件上放置重物。
To avoid module glass breakage, do not place heavy objects on the module.
不可重摔组件。
Anyway modules cannot be slammed.
不正确的运输或安装可能会损坏组件，运输时应使组件边框均匀受力，避免组件玻璃面和
背板受冲击或重压。
Faulty transport or installation can damage a module, so transport the bezel evenly to
prevent impact or heavy load on the glass and backplane.
八、电气安装 ELECTRICAL INSTALLATION
8.1 并网电气系统 Grid-connected electrical system
光伏系统产生的直流电可以转换为交流电并连接到公共电网上。关于连接可再生能源系统到公
共电网的政策，各地区有所不同。设计本系统时请向资深的系统设计工程师咨询相关信息。通常情
况下，安装并网光伏系统需要得到公共事业部门的认可、验收及正式批准。
The direct current generated by photovoltaic systems can be converted to alternating
current and connected to the public grid. Policies for connecting renewable energy systems to the
public grid vary from region to region. When designing this system, please consult a senior
system design engineer for relevant information. Installation of grid-connected pv systems
typically requires approval, acceptance, and formal approval by utilities.
8.2 接地 Ground connection
所有的组件框架和安装支架都必须合理地接地。使用推荐的连接端子并将接地电缆良好地连
接，固定到组件框架上。
