Here are some tips on how to clean a mono-si solar panels.the first cold wave of this winter has hit, and many places in the country have experienced strong cooling and snowfall weather, and many photovoltaic power stations are meeting the challenges of snow and ice. How should photovoltaic power plants be operated and maintained to survive the winter?
Snow and frost protection is the key
White snow, beauty is beautiful, but for photovoltaic power plants is not a beautiful thing. After snow, snow covering the surface of the component will affect the mono-si solar panels to receive sunlight, affecting the efficiency of power generation. Especially in extreme blizzard weather, the snow is too thick, once it exceeds the load-bearing capacity of the module, the photovoltaic module will have the possibility of deformation and damage.
In case of snowy weather, clear the snow in time after the snow clears to prevent the components from freezing. Pay attention to the use of soft items to prevent scratching the glass; Do not use hot water to pour components, cold and hot uneven will seriously damage the surface of components; Do not step on the component to clean, the component has certain load-bearing requirements, may cause hidden cracks or damage to the component, affecting the service life of the component.
Windproof measures are essential
Winter is often accompanied by strong winds, which will affect the normal operation and power generation efficiency of photovoltaic power plants. In particular, sudden and destructive extreme storm weather may also lead to the loosening and deformation of the connection parts of the support.
Before the strong wind strikes, it is necessary to carefully check the support interface and “repair and reinforce” in time to ensure that the power station can maintain stability during the wind; Comprehensively scan screw fasteners, fasteners, medium presses, edge presses and other “joints” for loosening, and tighten them in time.
Cleaning dust ensures high efficiency
After entering the winter, due to dry weather, heating and environmental pollution, haze weather will be more than spring, summer and autumn. Because the suspended objects in the low altitude will absorb and reflect the sunlight, the sunlight received by the component surface will be greatly reduced.
In hazy weather, manual cleaning, water gun cleaning and robot cleaning can be used to regularly clean the dust on the surface of the mono-si solar panels. Pay attention to the water pressure when using the high-pressure water gun to avoid component damage caused by excessive pressure.
