The weather is bad in winter, what should photovoltaic power plants pay attention to?

1. smog: there will be more smog weather in winter than in summer. It is suggested to Taitai Electric that smog mainly affects the power generation of distributed photovoltaic systems in two ways:

One is to weaken the solar radiation reaching the photovoltaic panel. Because the suspended matter at low altitude will absorb and reflect sunlight, the sunlight received by the module surface will be greatly reduced.

Secondly, if the haze weather lasts for a long time, particles on the surface of photovoltaic modules will accumulate, forming a layer of covering on the surface of modules, which will cause surface pollution of battery modules and further reduce power generation.

2. Dust: Due to collective heating and dry weather, there will be more dust in the air in winter than in other seasons. It is proposed to Taitai Electric that this will also affect the power generation of photovoltaic system. The research shows that dust covering the panel will affect the power generation effect of 10%.

3. Snow: If there is heavy snow on the components after snow, it needs to be cleaned. You can push the snow down with a soft object, and be careful not to scratch the glass. The assembly is load-bearing, but you can't step on it for cleaning, which will cause the assembly to crack or damage and affect its service life. It is generally recommended not to wait for the snow to be too thick before cleaning. When it snows, clear the snow above the module in time, otherwise the module will freeze excessively, which will affect the power generation and life of the system.
