CONNECTOR AND CABLE INSPECTION
连接器和线缆检查
It’s recommended to implement the following preventive maintenance every 6 months:
推荐每六个月进行一次以下的预防性维护：
（
1
）
Check the sealing gels of the junction box for any damage.
检查接线盒的密封胶，确保没有裂纹或缝隙；
（
2
）
Examine the PV module(s) for signs of deterioration. Check all wiring for possible rodent damage,
weathering and that all connections are tight and corrosion free. Check electrical leakage to ground.
检查光伏组件的老化迹象。包括可能的啮齿动物破坏、气候老化，以及所有连接器是否连接紧密、有无腐蚀现
象。检查组件是否接地良好。
（

）
Inspect all cables to verify that connections are tight, the cables are protected from direct sunlight and
sited away from areas of water collection.
检查所有电缆以验证其连接是否牢固；避免电缆受阳光直射且使其远离积水区域。
（

）
Check the torque of terminal bolts and the general condition of wiring. Also, check that mounting
hardware is properly torqued. Loose connections will result in damage to the array.
检查端子螺栓的扭矩和接线的各方面情况。此外，检查安装的硬件是否紧固到位。连接松动会导致阵列损坏。

CLEANING
清洗
Dust accumulation on the glass surface of the module will reduce its power output and may cause hot spots.
So the surface of PV modules should be kept clean. Maintenance work should be performed at least once six
months or frequently.
组件的功率输出和入射光强有关，灰尘堆积在组件的玻璃表面会影响入射光强，降低组件能量输出。所以光伏
组件表面应保持清洁，清洗工作应至少半年一次或根据污染程度来进行更频繁的清洗。
Warning: It should be carried out by trained personnel. Workers should wear PPE, such as goggles, electric
insulation gloves and safety shoes. The gloves should withstand DC voltages of no less than 2000V.
警告：组件的清洗工作应由受过训练的人员进行，工作人员应戴橡胶手套和工作靴，应能承受不低于
2000V
的
直流工作电压。
Use dry or wet soft cloths, sponges, etc. to clean the modules during the cleaning process, but do not put any
modules directly into the water, do not use corrosive solvents and do not wipe the PV modules with hard objects.
When the pressure water is used, the water pressure on the glass surface of the module must not exceed 700
KPa. The module must not be subjected to additional external force. If there is greasy dirt and other substances
on the surface of the PV module which are difficult to clean, conventional household glass cleaning agents can be
used; Do not use the alkaline and strong acid solvents. If necessary, use isopropyl alcohol (IPA) or other solution
according to the safety instructions to clean and ensure that no solution flows into the gap between the edge of
the module and the module frame.
应使用干燥或潮湿的柔软洁净的布料和海绵擦拭光伏组件，严禁使用腐蚀性溶剂或用硬物擦拭组件。在采用压
力水流清洗时，组件玻璃表面的水压不得超过
700
KPa，组件严禁承受额外的外力；但不要直接将任何组件放入水中。
光伏组件表面有油污等难清洁物质，可使用常规家用玻璃清洗剂；注意不能使用碱性及强酸性溶剂。如有必要，可
以按照安全指示使用异丙醇（IPA）或其他合适溶剂清洗，并确保溶剂没有流入组件边缘和组件框架之间的间隙。
Clean PV modules when the irradiance is below 200W/m
2
. When cleaning the modules, use a soft cloth
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
200W/m
2
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。
