What factors affect the winter power generation of photovoltaic power plants?
1. The first is the temperature, the low temperature of the component in winter will lead to an increase in the output voltage, affecting the operation of the inverter, ultra-low temperature will also cause component damage, so the low temperature in winter will lead to low efficiency of the component and reduce the power generation.
2. The short sunshine time in winter will lead to short power generation time and reduced power generation.
3. The winter sun height Angle is low, the photovoltaic panel receives less solar radiation energy, and the power generation will be reduced.
4. Haze weather will weaken the light, reduce the power generation efficiency of the component, and thus reduce the power generation.
5. Snow and dust will block sunlight into the component, reducing the power generation of the component.
Can snow destroy solar panels?
The power generation of the photovoltaic system is indeed affected by temperature, and the direct influencing factors are the irradiation intensity and sunshine duration and the operating temperature of the solar cell module. In winter, it is inevitable that the radiation intensity will be weak, the sunshine duration will be short, and the general power generation will be less than that in summer, which is also a normal phenomenon. However, because the distributed photovoltaic system is connected to the grid, as long as the grid has electricity, the household load will not have power shortages and power outages.
If there is heavy snow on the photovoltaic module after the snow, it needs to be cleaned, and soft objects can be used to push the snow down, taking care not to scratch the glass. The component has a certain load-bearing capacity, but it can not be cleaned on the component, which will cause hidden cracks or damage to the component, affecting the service life of the component.
It is recommended not to wait for the snow to be too thick before cleaning to avoid excessive icing of the components.
When it snows, how do our photovoltaic panels clean up the accumulation of snow?
1. Timely clear snow
You may need a tennis ball at this point. Using a tennis ball to bounce and vibrate the snow off an inclined panel would be a good way to slide it down. Of course, other tools can be borrowed. In this way you will find that the effect of your power generation system is multiplied;
2. Large Angle installation of solar panels
This can reduce the speed of snow accumulation and avoid the trouble of clearing snow from time to time. "Before you decide whether to choose 30 degrees or 40 degrees, obviously 40 degrees is a better plan."
3. Keep a little distance from the place when installing
The snow will not accumulate on the bottom as it falls off, so that it slowly accumulates over the entire battery assembly. Solar street lights are a low-cost and efficient alternative energy source. As an alternative to traditional electricity, new photovoltaic power generation systems are being installed in large numbers in homes. And once the grid is connected, even if the snow slightly obstructs solar power generation, the overall power supply is still normal.
