together with a mild detergent and clean water. Take care to avoid severe thermal shocks which might damage the
module by cleaning modules with water which has a similar temperature to the modules being cleaned. For example,
do not use cold water to clean the module when the temperature of it is high during the day, otherwise there will be
the risk of module damage.
应在辐照度低于

的情况下清洁光伏组件。清洁组件时，应使用软布和温和的清洁剂以及清水。清洁组
件时应保证水与组件之间的温差不大，以注意避免出现严重的可能损坏组件的热冲击。比如不在一天中光伏组件温
度较高的时候使用冷水清洗，以防损坏光伏组件。
It is forbidden to clean PV modules under the weather conditions of wind more than 4 grades, heavy rain or
heavy snow.
严禁在风力大于
4
级、大雨或大雪的气象条件下清洗光伏组件。
When cleaning PV modules, Do not step on the modules; Do not spray water on the backside of the module or
the cables; keep the connectors clean and dry; prevent fire and electrical shock from occurring; Do not use as steam
cleaner.
光伏组件清洁工作中，严禁踩踏组件、严禁流水溅射至组件背面和电缆，严禁清洁组件背面，要保证连接头的
清洁和干燥，防止电击和火灾危险；严禁使用蒸汽清洁器。
The back surface of the module normally does not need to be cleaned but, in the event this is deemed
necessary, avoid the use of any sharp projects that might damage the penetrating the substrate material.
组件的后表面通常不需要清洁；但在认为确实有必要对其进行清洗时，应避免使用可能引起损坏或穿透基底材
料的一切尖锐物体。
When cleaning the back surface of the module, take care to avoid penetrating the substrate material. Modules
that are mounted flat (0° tilt angle) should be cleaned more often, as they will NOT ''self-clean'' as effectively as
modules mounted at a 10° tilt or greater.
清洁组件的背面时，注意避免清洗液渗到材料底层。应稍微频繁地清洁水平安装的组件（
0°
倾斜角），
因为这
些组件不会像以
10°
倾斜角或更大倾斜角安装的组件那样具有
“
自清洁
”
功能。
Do not scrape or grind stains off surfaces while PV modules are dry, as this can cause minor scratches on the
surface.
组件干燥的情况下不要在表面将污渍刮掉或者磨掉，因为这样会在表面引起细小的刮伤。
