Weather also affects the amount of solar energy conversion. Weather conditions are not only determined by seasons and the way the earth moves around the sun, but also by other factors. For example, a weather surface may cover most of the United States, leading to days of heavy fog. When the clouds are quite thick, a large part of the solar energy will be blocked outside the solar panels. A similar situation can occur during short storms or snowstorms. The Great Lakes region is more vulnerable to cloudy, cloudy and foggy weather. Fog is caused by the temperature difference between air and land, but the effect of fog on solar energy device receiving sunlight is similar to the effect of dense clouds on solar energy device.
Another factor that affects solar photovoltaic cells is snow cover. At some time in the north and south, snow covers the solar panels, preventing them from absorbing sunlight. Usually, this is not a long-term problem, because most solar devices are dark, they can absorb some sunlight, generate heat, and melt the snow on the board. There is also a similar problem with snow, that is, when there is not enough rain to wash the solar panel, dust and stains will lock on the solar panel, so as to reduce the sunlight received. If a place is short of rain for a long time and a layer of ash falls on the board, it needs to be cleaned by maintenance personnel. In general, once every 4-6 weeks, the rain is enough to wash the solar panel clean.
