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。
Water requirements when cleaning:
清洗时对水质的要求：
（1）PH: 5～7；
PH值:5~7
（2）Chloride or salt content: 0 - 3000 mg/L
氯化物或盐分含量：0～3000 mg/L；
（3）Turbidity: 0-30 NTU
浑浊度：0～30 NTU；
（4）Conductivity: 1500～3000 μs/cm
电导率：1500～3000 μs/cm；
（5）Total dissolved solids: ≤1000 mg/L
总溶解固体：≤1000 mg/L；
（6）Water hardness: 0-40 mg/L
水硬度：0～40 mg/L；
（7）Non-alkaline water must be used, and softened water can be used when conditions permitted.
必须采用非碱性水，具备条件时应使用软化水。
6.3.1 MODULE INSPECTION AFTER CLEANING 清洗后组件检查
（1）Ensure that the module under visual inspection is clean, bright and free of stains;
目视组件整体外观是否清洁、明亮、无污渍；
（2）Spot check to verify whether there is soot deposit on the module surface;
抽样检查组件表面是否有积灰存在；
（3）Check to whether there are visible scratches on the surface of the module or not;
