Photovoltaic installation application? These details can not be ignored!

1. Details of the safety hazards can not be ignored

For flat photovoltaic power station, conventional cleaning methods cleaning or there will be accumulated ash band. The lower edge will definitely form hot spots.

Solve the problem of ash accumulation along the lower edge of the component: the use of photovoltaic water-conducting clamps, water accumulation of ash together with the discharge of photovoltaic components on the surface, you can avoid the formation of hot spots. On the one hand, to protect the PV module from the accumulation of ash caused by the hot spot problem, on the other hand, can also play a role in enhancing the effect of the power station's power generation.

2. Problems with hanging MC4 connectors on DC cables

With the passage of time, rain and water washout during cleaning, the problem of leakage, arc pulling, until melting occurs.

In the summer when the irradiation is good and the temperature is high, the melting process of individual MC4 connectors can seriously burn through the colour steel plate of the roof of the plant and cause a fire, or damage the backsheet of the PV modules in the process of melting.

3. Lighting tape protection and safety issues

Lighting belt generally use hot melt material, lighting belt material melted by heat after the formation of lighting belt ventilation holes, can play a role in smoke exhaust after fire. Lighting belt of this hot melt material is not load-bearing capacity, and its outdoor use of the environment is relatively poor weather resistance. Installation of a protective net on top of the lighting strip, the protective net with photovoltaic

Installation of fixture and colour steel plate system connection, the safety risk of falling from height.

4. Permanent setting of critical edge protection facilities

The programme selection and material selection of the proximity protection setup must consider the applicability of long-term outdoor use to avoid problems in the subsequent production phase.

5. The radius of coverage of the lifeline system

After the installation of the lifeline system, consider the length of the safety rope of the elevated operator's hanger is just a few metres long, after the completion of the construction of this lifeline system, when the personnel rooftop work, the end of the safety rope hangs on the lifeline, can it cover the construction or maintenance phase.
