Some problems with photovoltaic power generation - three
Will the photovoltaic system still work if it is continuously rainy or foggy after installation?
Answer: Photovoltaic cell modules can also generate electricity under certain weak light, but due to continuous rainy or hazy weather, the solar irradiance is low, and if the operating voltage of the photovoltaic system does not reach the starting voltage of the inverter, then the system It won't work.
The grid-connected distributed photovoltaic power generation system and the distribution network are operated in parallel. When the distributed photovoltaic power generation system cannot meet the load demand or does not work due to cloudy weather, the grid power will be automatically replenished, and there is no power shortage and power failure. problem.
Will there be insufficient power when the weather is cold in winter?
A: The power generation of photovoltaic systems is indeed affected by temperature. The direct influencing factors are the intensity of radiation and the duration of sunshine and the operating temperature of solar modules. In winter, it is inevitable that the intensity of radiation will be weak, the length of sunshine will be short, and the amount of electricity generated will be less than that in summer. This is also a normal phenomenon. However, since the distributed photovoltaic system is connected to the power grid, as long as the power grid has electricity, there will be no power shortage and power failure in the household load.
Does the photovoltaic system have electromagnetic radiation and noise hazards to users?
Answer: Photovoltaic power generation system converts solar energy into electric energy according to the principle of photovoltaic effect, without pollution or radiation. Inverters, power distribution cabinets and other electronic devices will pass EMC (electromagnetic compatibility) testing, so there is no harm to the human body. The photovoltaic power generation system converts solar energy into electric energy without causing noise. The noise level of the inverter is not higher than 65 decibels, and there is no noise hazard.
