③
In the case of insufficient irradiance (very low), if the voltage difference between the
terminal and the rated value is more than 5%, it indicates that the module is not connected well.

Maintenance

应保持太阳能电池方阵采光面的清洁，应先用清水冲洗，然后用干净的纱布将水迹擦干，切勿
用有腐蚀性的溶剂冲洗或用硬物擦拭。遇风沙和积雪后，应及时进行清扫。一般应至少每月清
扫 1 次。
should remain on the surface of the solar cell phalanx daylighting is clean, you should rinse,
then water wipe with a clean gauze, do not use corrosive solvent wash or wipe with hard objects.
In case of sand and snow, should be cleaned in time. Generally, it should be cleaned at least once
a month.
 值班人员应注意太阳能电池方阵周围有没有新生长的树木、新立的电杆等遮挡太阳光的物体，
以免影响太阳能电池组件充分地接受太阳光，一经发现，要报告电站负责人，及时加以处理。
The personnel on duty should pay attention to whether there are new trees, new poles and
other objects blocking the sunlight around the solar cell array, so as not to affect the solar cell
module to fully accept the sunlight, once found, to report to the responsible person of the power
station, timely treatment.
 带有向日跟踪装置的太阳能电池方阵，应定期检查跟踪装置的机械和电性能是否正常。
Solar arrays that incorporate a suntracking device spend time periodically checking the
mechanical and electrical properties of the device.

太阳能电池方阵的支架，可以固定安装，也可按季节的变化调整电池方阵与地面的夹角，以便
太阳能电池组件更充分地接受太阳光。通常的调整角度是（以北半球为例）：①春分以后的接
收角是当地的纬度-11
0
48
，
；②秋分以后的接收角是当地的纬度+11
0
48
，
；③全年平均的接收角
是当地纬度的+5
0
。

the bracket of the solar cell array can be fixed and installed, and the included angle
between the solar cell array and the ground can also be adjusted according to seasonal
changes, so that the solar cell modules can more fully receive sunlight. The usual adjustment
angles are (taking the northern hemisphere as an example):
①
the receiving angle after the
spring equinox is - 11
°
48 of the local latitude;
②
the receiving angle after the autumn
equinox is + 11
°
48 of the local latitude;
③
the annual average receiving angle is + 5
°
