In most people’s cognition, solar photovoltaic systems want to generate electricity need to have sunlight, so many friends that installed or want to install photovoltaic systems can not help but worry: the cloudy and rainy weather will not affect the photovoltaic power generation? If it snows in winter, will it still be able to generate electricity?
It is understood that the solar photovoltaic system in obtaining energy, indeed with the four seasons, day and night and cloudy and other meteorological conditions. But in rainy and snowy weather, although there is no direct sunlight, the power generation of photovoltaic systems will be relatively low, but not no power generation. PV modules can also generate electricity to a certain extent under low light conditions. In the previous data showed that a 20 kW PV system can still generate 20 kWh of electricity on a rainy day.
Although the weather factor is out of our control, we can do a good job of maintaining the PV modules in our daily lives after ensuring a professional installation. After the module starts to generate electricity normally, regular inspection and cleaning is very important, which can understand the operating condition of the PV system in a timely manner, and regular cleaning can remove the accumulated dust and other stolen dirt on the surface of the module, and improve the efficiency of the module power generation.
