In recent years, more and more people have used photovoltaic power generation, and many people are worried about whether solar cell photovoltaic panels will generate radiation? Wi-Fi V S photovoltaic power generation, which one has the most radiation? What is the specific situation?
PV
Photovoltaic power generation directly converts light energy into DC power through the characteristics of semiconductors, and then converts the DC power into AC power that can be used by us through an inverter. There are no chemical changes and nuclear reactions, so photovoltaic power generation will not have short-wave radiation.
radiation
Radiation has a wide range of meanings. Light is radiation, electromagnetic waves are radiation, particle flow is radiation, and heat is radiation.
So it is clear that we are in all kinds of radiation.
What kind of radiation is harmful to humans?
Generally speaking, "radiation" refers to those radiations that are harmful to human cells, such as those that can cause cancer, and those that have a high probability of causing genetic mutations.
Generally contains shortwave radiation and some streams of high-energy particles.
Do photovoltaic panels produce radiation?
For photovoltaic power generation, the power generation mechanism of solar modules is completely the direct conversion of energy. In the energy conversion in the visible light range, no other products are generated in the process, so no additional harmful radiation is generated.
The solar inverter is just a general power electronic product. Although there are IGBTs or triodes in it, and there are several tens of k switching frequencies, all inverters have metal shielding shells and meet the electromagnetic compatibility requirements of the global regulations. certification.
Wi-Fi VS photovoltaic power generation, which one has the most radiation?
Wi-Fi radiation has always been criticized, and many pregnant women avoid it. Wi-Fi is actually a small local area network, mainly for data transmission. And as a wireless device, Wi-Fi has a transmitter that does generate electromagnetic radiation around it. However, the normal Wi-Fi operating power is between 30~500mW, which is less than the power of normal mobile phone (0.125~2W). Compared with mobile phones, Wi-Fi devices such as wireless routers are much farther away from users, which makes people accept much less power density of their radiation.
