光伏组件安装手册

安装手册请在使用或者安装贝达系列太阳能光伏组件之前仔细阅读本手册。

该光伏组件在光照情况下会产生电流电压。

请遵守所有的电器安全防范措施。

只有有资质的人员才可以安装或者维修该组件产品。

请不要损坏太阳能电池组件或者造成太阳能电池组件表面的刮伤。

潮湿的环境会有导电的危险,请不要在组件潮湿的时候对组件做任何操作。

1.安全预防措施1.1光伏组件没有开关。

只能通过将光伏组件挪离光照或者用布、硬纸板或者完全不透光的材料遮挡,或者将组件正面放置在光滑、平坦的表面上才会使组件停止工作。

1.2光伏产品在光照情况下会产生直流电,所以会有电击或者烧伤的危险。

即使在没有连接负载或者外电路的情况下,组件也会产生电流电压。

在光照大于5%的情况下,组件就会产生最大电压,随着光照强度的增大,产生的电流和功率也会不断增加。

所以在阳光下对组件动作时,请使用绝缘工具,同时佩戴橡胶手套。

最好,在操作过程中,把电池板表面用不透光材料覆盖。

1.3组件产生的功率可能会高于铭牌上的额定标称。

工厂标准的额定输出是在光强1000watts/m2,温度25℃,大气质量1.5的情况下测量的。

雪和水的反射也会增加光强,因此会造成电流和输出功率的增大。

另外,温度低于25℃时组件的电压和功率也会相应的增长。

1.4贝达太阳能电池组件的表面为钢化玻璃,但是操作时仍要小心,不合理的操作会造成组件表面的钢化玻璃破碎。

如果正面的玻璃破碎或者背面的聚合物烧坏,任何和组件表面或者铝合金边框的接触都可能造成电击,尤其在组件潮湿的情况下。

破损的组件必须由专业人员妥善处理。

1.5贝达太阳能电池组件的设计是仅适用于陆地的,所以不能在太空、海洋或者聚光环境使用。

除了上述环境,组件也不能被安装在有可能接触到任何盐水或可能成为部分或全部淹没在淡水或海水的情况,建议把组件安装在离海最少500m的地方。

2.守则和条例光伏组件的机械安装和电气安装应该参照相应的法规,包括电气法、建筑法和电力互联需求。

这些条例随着安装地点的不同而不同,例如建筑屋顶安装、汽车应用等。

要求也可能随着安装系统电压,使用直流或者交流的不同而不同。

具体条款请联系当地的权威机构。

3.机械安装3.1可以将组件按照从水平到垂直的任何一个角度安装。

3.2合适的安装倾角和面向的方位角应该以组件产品得到最多的光照为标准。

3.3应该通过组件背面的安装孔将组件安装在支架上。

3.4请不要在组件的边框上钻附加的安装孔,否则会影响组件的质量跟寿命,且经过另外加工的组件将不在质保范围内。

3.5同时,请不要在组件边缘设置支撑点。

3.6同一个系统中组件的电性能需一致。

3.7降水可能从组件背后的小口子进入。

确保出水口在安装之后不能被堵住。

3.8保持良好的通风,这样有利于组件电性能输出最大化。

4.电气安装4.1组件应安装在可以得到最大光照的位置并确保不被遮挡,包括灰尘的沉积等。

即使部分遮挡也会减少组件和系统的输出功率。

同时,组件部分的遮挡也会造成遮挡部分内部温度的升高,这样会造成低的输出功率,也会缩短组件的寿命。

所以在组件生产过程中都使用了旁路二极管。

应该在每个组件或一系列组件上串联一个阻塞二极管,可以避免当组件串联或者与蓄电池串联时产生的过电流逆流。

4.2必要时,根据当地法规、选择经过认证、且满足系统电压和组件的最大额定保险的保险丝或断路器。

4.3所有电气器件的额定标称应不小于系统的额定标称。

请不要使用超过铭牌上组件所能承受的最大系统电压。

所有的组件边框应该可靠接地。

4.4正常情况下,组件产品产生的电流和电压值,可能会相对于标准测试条件下得到的偏高。

所以,在确定光伏发电系统配件时,如:额定电压、导线容量、保险丝容量和组件功率输出有关联的参数时,应将相应的短路电流和开路电压放大1.25倍以上。

组件的电性能参数如ISC, Voc和Pmax的标称值与在标准测试条件下1000watts/m2的辐照度,25℃(77°F)的环境温度,光照度参照ASTM E 892,测得的数据,在实际的安装使用中根据光强度及温度的变化有±10%以上的偏差。

4.5贝达太阳能的组件产品带有相应的电缆线和连接器。

这些设计便于组件间的串联。

每一个组件有两根单独连接到接线盒内的导线,一个正极,一个负极。

通过把一个组件导线另一端的正极接口插入相邻组件的负极导线的插口,就可以把两个组件串联。

4.6需要一个单独的返回电缆线,把组件的正极和负极终端与负载相连。

提前联入电缆线的公母接口可能需要用来作为返回电缆线的接口或者源电路的终端接口。

4.7所有的组件都安装有一个旁路二极管。

5操作和维护5.1不需要日常维护。

但是建议周期性的检查组件是否破损,如:玻璃,背板,铝合金边框。

检查电器接口是否松动或者被腐蚀。

5.2在没有清洗的情况下,光伏组件也可以有效地工作,但是去除玻璃表面地灰尘可以增大输出。

使用湿的海绵或者布擦拭玻璃表面。

维护时,请佩戴橡胶手套。

6运输、储存组件当取出,运输,存储组件的时候要小心。

6.1运输组件的时候要使组件垂直放置。

6.2搬组件的时候要用双手抓住边框,不要直接用手去拉接线盒上的电缆线。

6.3禁止撕扯组件。

6.4不要在组件上放置其它物品。

6.5不要使组件遭受撞击,不要站在组件上面。

6.6不要使用尖锐的工具在组件上做标记。

6.7保持所有的电接触是干燥没有污染的。

6.8 假如需要临时存储组件,需要一个干燥,通风良好的空间进行存储。

Installation ManualPlease read the installation manual before using or installing a Beida Solar photovoltaic module. This photovoltaic module produces electricity when exposed to sun light. Follow all applicable electrical safety precautions. Only qualified personnel should install or perform maintenance work on this module. Do not damage or scratch the rear surface of the module. Do not handle modules when they are wet, this condition may increase the risk of electric shock.1. Safety Precautions1.1 Photovoltaic modules have no on/off switch. Modules can be rendered inoperative only by removing them from sunlight, or by fully covering their front surface with cloth, cardboard, or other completely opaque material, or by working with modules face down ona smooth, flat surface.1.2 Photovoltaic modules produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. Modules produce voltage even when not connected to an electrical circuit or load. Modules produce nearly full voltage when exposed to as littleas 5% of full sunlight and both current and power increase with light intensity. Use insulated tools and rubber gloves when working with modules in sunlight.It would be best by covering their front surface fully with completely opaque materials when operating on the modules.1.3 Modules may produce higher output than the rated specifications. Industry standard ratings are made at conditions of 1000 watts/m2 and 25℃ cell temperature, AM 1.5. Reflection from snow or water can increase sunlight and therefore boost current and power. In addition, temperature below 25℃can substantially increase voltage and power.1.4 Beida Solar modules are constructed with tempered glass, but still must be handled with care, If the front glass is broken or if the polymer back-skin is torn, contact with any module surface or the frame can produce electrical shock, particularly when the module is wet. Broken or damaged modules must be disposed of properly.1.5 Beida Solar modules are intended for use in terrestrial applications only, thus excluding aerospace or maritime conditions or use with sunlight concentration. Excluded applications include, but are not limited to, installations where modules are likely to come in contact with any salt water or where likely to become partially or wholly submerged in fresh or salt water, we suggested that the modules should installed at least 500m away from the sea.Codes and RegulationsThe mechanical and electrical installation of Module systems should be performed in accordance with all applicable codes, including electrical codes, building codes, and electric utility interconnect requirements. Such requirements may vary for mounting location, such as building rooftop or motor vehicle applications.Requirements may also vary with system voltage, and for DC or AC application. Contact local authorities for governing regulations.Mechanical Installation3.1 Modules may be mounted at any angle from a vertical orientation to a horizontal one. 3.2 The appropriate fixed tilt angle and azimuth orientation should be used in order to maximize the exposure to sunlight.3.3 Modules should be bolted to support structures through mounting holes located in the fram e’s back flanges only.3.4 Creation of additional holes for mounting is not recommended and will invalidate the warranty.3.5 Modules should not be mounted by supports at the ends.3.6 Modules in the same system should be in the same electrical properties.3.7 The rain may enter the modules from the small hole in the back, to ensure that the outlet can not be blocked after installation.3.8 Maintain a good ventilation will make a maximize electrical performance output. Electrical Installation4.1 Modules should be mounted to maximize direct exposure to sunlight and to eliminateor minimize shadowing. Even partial shadowing can substantially reduce module and system output. Furthermore, partial shadowing can elevate the shaded portion’s internal temperature, which may lower output and shorten module life. Bypass diodes are factoryinstalled. Blocking diodes should be installed in series with each module or series string to prevent possible back flow of energy through the modules when modules or strings are connected in parallel or used in conjunction with a battery.4.2 Whenever necessary to comply with local codes, use a listed fuse or circuit breaker, rated for the maximum series fuse rating of the module and the system voltage.4.3 All electrical components should have ratings equal or greater to the system rating. Do not exceed the maximum allowable system voltage as listed on the module label. All module frames should be grounded for safety.4.4 Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of short circuit current, and open circuit voltage, marked on modules should be multiplied by a factor of more than 1.25 when determining component voltage ratings, conductor capacities, fuse sizes, and size of controls connected to the module output. Rated electrical characteristics are more than10 percent of measured values at Standard Test Conditions of: 1000 W/m2 , 25℃ cell temperature and solar spectral irradiance per ASTM E 892.4.5 Beida Solar modules are equipped with factory-installed wires and quick connectors. These modules have been designed to be easily interconnected in series. Each module has two single-conductor wires, one positive and one negative, that are pre-wired inside the junction box. The connectors at the opposite end of these wires allow easy series connection of adjacent modules by firmly inserting the male connector of a module into the female connector of an adjacent module until the connector is fully seated.4.6 A separate return wire or wires may be required to run the positive and negative terminations of the series string of modules to the load. Male and/or female connectorspre-attached to wires may be used at the string terminations for return wire connections and/or for source circuit box terminations.4.7 All modules also have a bypass diode installed.Operation and Maintenance5.1 No routine maintenance is required. However it is advisable to perform periodic inspection of the modules for damage to glass, back-skin, or frame. Check electrical connections for loose connections and corrosion.5.2 Photovoltaic modules can operate effectively without ever being washed, although removal of dirt from the front glass can increase output. The glass can be washed with a wet sponge or cloth. Wear rubber gloves for electrical insulation.Transport, Storage Modules6.1 Modules should be put vertically when transport.6.2 When move the module, use both hands to catch the module frame,not directly pull the cable on the junction box by hands.6.3 It’s prohibition to tear at the modules.6.4 Do not put any other goods on the modules.6.5 Do not make the modules to impacted, and stand on the module is also prohibition.6.6 Do not scratch the rear surface of the modules.6.7 To keep all of the electrical contact working in a dry and un-contaminated condition.6.8 If a temporary storage is needed, the storage space must be under a dry, ventilated condition.。
