2.2.5 The modules should be installed in the position where is full of sun exposure without shadow at
any time.
2.2.6 Generally, it is not recommended to be installed in the place where is less than 500 meters from
the sea. The modules, as a general rule, can guarantee 25 years of useful life if the module is installed in the
place where is more than 3 km from the sea. If the module is installed in the place where is 500-3000m to
the sea, the modules need extra protection. (For example, increasing the thickness of the oxide film of
Aluminum metal alloy frame, and increasing the anti-corrosion treatment of frame connection.)
2.2.7 When a storage battery is used in the photovoltaic system, the battery must be installed
correctly. Therefore, it can protect the safety of photovoltaic system. The installation of the storage battery
should follow the instructions of storage battery manufacturer.
2.2.8 It is recommended that the height of the module is 0.3-1m higher than actual environment.

2.3.1 串联连接的光伏组件应按照相同的朝向和角度进行安装。
2.3.2 如果连接到独立光伏系统，组件的安装角度应该根据季节和光照的情况来获得最大化的功
率输出，一般来讲，如果组件的输出在一年内光照强度最低的情况下也可以满足的话，那所选择这
个角度的组件输出就能满足全年的需求；对于并网连接的系统，组件的安装角度应该基于全年的输
出最大化这个基础原则来选择。
2.3 Installation Inclination Angle Selection
2.3.1 PV modules connected in series should be installed in the same orientation and angle.
2.3.2 If connected to an independent photovoltaic system, the installation angle of the module should

illumination intensity, if the power generated by module with certain angle can satisfy the lowest power
generation, it is think that the modules with the certain angle can satisfy the power generation all year
around. For grid-connected system, the installation angle of modules depends on the max power generation
all year around.
2.4 支架选择
系统设计者或安装者负责载荷计算，使组件能够承受所有预定的载荷条件；这是支架安装商所
必须要提供的保证。所选用的支架必须经过具有静态力学分析能力的第三方测试机构检验和测试。
2.4.1 双面组件支架不遮挡背面电池片
在支架结构设计时，支架构件不能横穿组件电池片区域，只能在组件边沿设置斜梁及连接辅件，
同时逆变器安装位置也不能在组件背后，而应该安装在组件侧面，避免影响到组件背面的反射光。
图3 双面组件支架不遮挡背面电池片
2.4 Choose the Photovoltaic Support
The system designer or installer have responsible for calculation the system load to make sure all
module can support the estimated load. The module support manufactures should supply qualitied module
supports. The support, which is used for photovoltaic system, should has the third test institution
certification about static mechanical analysis ability.
2.4.1 Installation of bifacial module without shading the back of module
When designing the modules’ support structure, the support components cannot cross the module cell
area. The support components can be set up at the edge of the module. At the same time, the inverter should
be installed at the side of the module instead of back. If the inverter is installed at the back of the module, it
may reduce the reflected light and reduce power generation of the back of the module.

Figure 3 The component bracket does not cover the back battery
2.5 逆变器选择
在选择逆变器类型时，需要考虑光伏组件阵列的输出功率、开路电压、短路电流。组件阵列的
最小电压应大于逆变器的开启电压，以保证逆变器的正常工作。
2.5.1 阵列串联组件数量计算
请使用与太阳能系统配套的设备、连接器、电线、支架。在特定的系统中，一定要使用相同类
型的组件。在确定光伏系统相关部件的额定电压、导线容量、保险丝容量、控制器容量等和组件输
出功率有关联的参数时，请参照组件标签上显示的短路电流(Isc)和开路电压(Voc)的值进行合理的设
计。
在正常的室外环境下，光伏组件产生的电流和电压可能与参数表中的参数不同。参数表中的参
数是在标准测试条件下(STC)测得，所以关于解决不同地区的光伏发电系统的参数，如额定电压、导
线容量，保险丝容量，控制器容量和组件输出功率时，通常应使用组件标签上的 Isc 和Voc 的值应
乘以 1.25 倍的冗余值设计和安装。若双面发电的组件安装在背面环境反射条件好的地方，需适当增
加冗余值。
确保每个阵列的系统电压不超过组件最大系统电压，以及控制器、逆变器等子设备的额定电流
和电压。
组件之间的连接：根据系统设计要求输出电压和电流，组件通过自身导线串联或并联起来；串
联组件的最大数量（N）建议使用下列公式计算；并联组件的数量与标准测试条件下选择的电气设
备（逆变器、控制器）有关。

N 串联组件数量。
Vmax 最大系统电压（见产品标签或数据表）。
Voc 组件开路电压（见产品标签或数据表）。
Tc(voc) 组件开路电压温度系数（参见数据表）。
Tmin 最低环境温度。
2.5 Choosing the Photovoltaic Inverter
When choosing photovoltaic inverter, it needs consider the power, open-circuit voltage, short-circuit
current of PV modules array. The minimum voltage of the module array should be higher than the threshold
voltage of inverters to guarantee the inverters regular work.
2.5.1 Calculation of modules’ number in series array
Please use the suitable equipment, connectors, wires and rack which match with solar power system.
Please make sure the type of the modules is same in a single PV system. When determining rated voltage,
wire capacity, fuse, the controller capacity and module output power of relevant parts of PV system, please
accord to the short-circuit current (Isc) and open circuit voltage (Voc) showing on modules’ label to
determine suitable parameters.
In normal outdoor conditions, the current and voltage generated by module may be different from the
parameters listed in Table. The parameter list in table is measured under standard test conditions (STC). In
different outside climate surrounding, because of different power generation coefficient, the actual
parameters, including rated voltage, wire capacity, fuse, the controller capacity and module power output, is
different if modules working in different area. In order to get the actual module’s electrical parameters,
usually,the photovoltaic system designers or installers can use short-circuit current (Isc) and open circuit
voltage (Voc) noted on modules’ label multiply by 1.25 (redundant value). If the bifacial modules are
installed at high reflective surrounding, the redundant value can increase suitably.
Please make sure the system voltage of each modules’ array is lower than the maximum voltage of
photovoltaic system, rated voltaic of inverter and controller. The system current of each modules’ array is
less than maximum current of photovoltaic system, rated current of inverter and controller.
The connection of modules: According to the system requirement of output voltage and current,
modules are connected in series or parallel. The maximum number of series components (N) is

16

连云港神舟新能源有限公司 文件版本号 V2.4 页码 16 / 49
recommended to be calculated using the following formula. The number of modules in parallel has relate to
the parameters of electrical equipment (such as inverter and controller) in STC.
N Number of modules in series.
Vmax Maximum system voltage
Voc Open circuit voltage of each module(refer to product label or data sheet).
Tc(voc) Thermal coefficient of open circuit voltage for the module(refer to data sheet).
Tmin The lowest ambient temperature.
2.6 双面组件排布与布局优化
对于标准方阵而言，一般的接线方式是两种，第一种上下串联，第二种上下分开串联。下面一
行的距地高度和上面一行的距地高度是远远不同的（尤其是在组件竖向布置时）。而此时，在进行组
串接线时，如果选择方式 1，受下面一行组件低电流的影响，上面一行组件的电流也会降低，从而
使得整体的输出功率有所降低。而如果采用方式 2，此时上下两行单独成串，互不影响，充分的利
用的双面组件的性能，提高了发电量。上下排组件的增益效果是不同的，上排的组件增益相对较高，
下排的组件增益相对较低，为了降低组串的失配，我们还是建议有条件的选择方式 2的组串形式，
同时将上下两串接入逆变器的不同 MPPT 下，这就是目前最优的接线方式。
图4 组串接线优化
2.6 Bifacial Module Arrangement and Layout Optimization
Generally, for normal modules’ array, there are 2 methods of module connection. The first method
connects the upper module and the under module in series. The second method separates the upper and the
under modules. All upper modules connect in series, and all under modules connect in series separately.
There is significant height difference between upper and under modules. The significant height difference
lead to light illumination difference between upper and under modules. The light illumination difference
lead different working current of the module. If choosing the first method, the under module, which has

17
文件名称 双玻光伏组件安装说明书
文件编号 HTL-TR-I063 (V2.4)
连云港神舟新能源有限公司 文件版本号 V2.4 页码 17 / 49
lower working current, will decrease the working current of the upper module. The decreasing of upper
modules’ working current will reduce the whole power generation of photovoltaic system. When choosing
the second method, the upper modules and the under modules have different working current. It can
decrease power loss due to working current mismatch, which improves the advantage of bifacial modules
and increases whole power generation of photovoltaic system. The light illumination rises with height
increasing at the same outside surrounding. Therefore, the upper modules have higher light illumination
than the under modules. In order to declining the current mismatch, we advise the second modules
connection method. At the same time, please connect the upper/under modules’ array to the different
MPPTs of the inverter individually. This is the best method of modules’ array connection for photovoltaic
system.
