Since last week, there has been a sudden storm of rain and snow in the northern region, especially in the three provinces of Northeast China, where the blizzard went down. Severe weather has caused great pressure on the photovoltaic power station, and if it is not cleaned properly, it will cause irreversible damage to the photovoltaic power station. Today, Wheat Photovoltaic recommends some methods to clear the snow.
Methods and precautions for cleaning the snow on the photovoltaic power station:
It is generally recommended not to wait until the snow is too thick to clean up, to avoid the components from freezing, too heavy snow may crush the components.
Generally choose early morning or evening, because the sun is weak during these periods and the power loss is small.
1). Avoid operation under strong light. First, man-made shadows can cause hot spot effects on photovoltaic modules. Second, high voltages and large currents are likely to be generated during these periods, which may cause harm to the human body.
2). Do not use hot water to pour photovoltaic modules. Uneven cold and heat will seriously damage photovoltaic modules.
3). You can use soft objects to push down the snow. Be careful not to scratch the glass on the surface of the module (otherwise it will reduce the light transmission).
The tennis ball can be used to bounce and vibrate gently on the inclined photovoltaic module to make the snow slip off.
Snow removal must be clean, do not underestimate the strip-shaped snow, the blocked part will fail the entire photovoltaic module, which will significantly reduce the power generation efficiency.
The components have a certain load-bearing capacity, but you cannot step on the components to clean them, which will cause the components to crack, affect the life of the components, and reduce the power generation.
The components and brackets have many sharp corners, so be careful to avoid being scratched.
Be sure to pay attention to anti-skid to avoid falling injuries, especially to clean the snow on the roof photovoltaic power station.
Suggestions for the installation of photovoltaic power plants in snowy areas:
1. Large Angle Installation Of Photovoltaic Panels.
In the best inclination range, installing photovoltaic modules at a large angle can make the snow slide down on its own, eliminating the trouble of frequent snow cleaning.
2. Keep Some Distance From The Ground During Installation.
In this way, the snow will not cover the components after falling and accumulating on the bottom.
