Severe Winter Snowfall Is Inevitable, How To Operate And Maintain Photovoltaic Power Plants?

how to operate and maintain photovoltaic power plants?

Today, many places have been "baptized" by winter snow, the cold wave has arrived, and the real cold has just begun. As a PV person, don't forget: your PV power plant is still outside. When snow blocks the sun, it blocks the profits. What should be done with the snow in the photovoltaic power station? What problems do we need to pay attention to in the inspection and operation and maintenance of power stations in low temperature and snowfall weather? Today, Mutian small class will take you into the photovoltaic power station in the snow.

The operating temperature of the general module is in the range of -40~80°C, and the operating temperature of the inverter is kept in the range of -25°C~60°C, so the extremely extreme low temperature environment may affect the normal operation of the equipment. At the same time, the low temperature environment may cause frost heave phenomenon in the foundation, destroy the foundation, and cause the phalanx, inverter, distribution box, box transformer, etc. to tilt or even collapse. A large amount of snow is more likely to cause deformation or even damage to the modules, and long-term shading or freezing of the modules will affect the power output of the power station.

 

 

1.

Use soft tools to remove snow

It is forbidden to use shovels to remove snow, which will scratch the glass of the module and affect its power generation efficiency.

2.

Do not step on the module to clean

which may cause cracks or damage to the module and affect the life of the module.

The snow should be cleared regularly to avoid ice formation of components and even bending of panels.

 

 

Snow removal needs to be clean, and the blocking of small pieces of snow may cause the overall failure of the module, resulting in the reduction of the power generation efficiency of the system.

Do not rinse the components with hot water to avoid cracking and damage to the battery panel caused by uneven cold and heat.

Other effective ways to remove snow:

(1) For small household power stations, the battery board can be covered with cloth or plastic paper before snowfall, and it can be uncovered after snowfall

(2) UAV spraying de-icing and snow remover, if there are conditions, it is recommended to buy snow and anti-icing spraying concentrate on glass surface on the market, which will not damage the surface of the module, and can also help the snow melt quickly and prevent icing.
