Are solar photovoltaic panels harmful to human radiation?

Does photovoltaics emit radiation? Firstly, before addressing this issue, we need to have a certain understanding of radiation.

Firstly, everything has radiation. As long as the temperature is above absolute zero degrees, heat is constantly transmitted to the outside in the form of electromagnetic waves. This way of transmitting energy is called radiation. So radiation is ubiquitous. But there are two types of radiation, the first is ionizing radiation, and the second is non ionizing radiation. In fact, the only one that is truly harmful to the human body is ionizing radiation. The reason why ionizing radiation is powerful is that it can directly penetrate the surface of living organisms, enter the interior of atomic nuclei, and directly contact the electrons inside, so it is also called ionization. But these are probably only available in physics laboratories.

 

 

In daily life, we hardly encounter ionizing radiation, which is very safe. And non ionizing radiation refers to what we usually refer to as mobile phones, computers, WiFi, monitors, etc. In fact, the radiation of these things doesn't even need to be calculated in numbers because we often use them, and what we usually calculate is actually another thing, electromagnetic radiation value. However, the total radiation of all of these things may not be as much as the radiation you emit when you go out to bask in the sun for a while at noon.

So now everyone knows, is the saying 'once it's installed, there won't be any grass growing within a radius of three kilometers' really true. And photovoltaic power generation directly converts light energy into direct current energy through the characteristics of semiconductors, and then converts the direct current into alternating current that can be used by us through inverters. There are no chemical changes or nuclear reactions involved, so photovoltaic power generation does not emit short wave radiation. However, solar inverters are just ordinary power electronic products. Although they have IGBTs or transistors and switch frequencies of tens of kilowatts, all inverters have metal shielding shells and comply with global electromagnetic compatibility certifications.

How about it? I believe everyone already knows the answer to the question of whether photovoltaic power generation has radiation and whether it is harmful to human health.
