担心光伏电站的辐射有危害？其实还没你家电磁炉辐射大！

要想知道光伏电站的辐射有多大，首先，我们要先了解一下什么叫辐射。简单通俗来说，我们把能量以电磁波和粒子的形式时刻不停地向外扩散，这种传送能量的方式被称为辐射。

生活中处处充满了辐射，比如：热辐射、太阳辐射、光线辐射等。围绕在人类身边的天然磁场、家用电器等都会发出强度不同的辐射。所以明确来说我们本身就处在各种辐射之中。有些辐射因为能量较大，会对生物体造成一定的影响，但是很多辐射我们还是离不开呢，比如太阳的辐射——阳光。

光伏发电是将光能通过半导体的特性直接转化为直流电能的，再通过逆变器将直流电转换成可以被我们使用的交流电。

光伏组件本身在发电时并不产生任何电磁辐射，但是逆变器等电力及电子设备在运行时会影响周边的电磁环境，因此所有的逆变器都有金属屏蔽外壳，并且符合全球规定的电磁兼容性的认证。

如下图实测，在距离10cm左右时，逆变器的辐射值已经是0了，而电磁炉的辐射值为13.31。

经科学测定，太阳能光伏发电系统的电磁环境低于各项指标的限值。在工频段，太阳能光伏电站电磁环境甚至低于正常使用的常用家用电器时产生的量值，不会对人身健康产生影响。

To know how much radiation a photovoltaic power station has, first of all, we have to understand what radiation is.  In simple terms, energy is constantly spreading out in the form of electromagnetic waves and particles, and this way of transmitting energy is called radiation.  

The picture  

Life is full of radiation, such as: thermal radiation, solar radiation, light radiation and so on.  The natural magnetic field around people, household appliances and so on will emit different levels of radiation.  So specifically we are exposed to all kinds of radiation.  Some radiation can affect living organisms because of its high energy, but we still need a lot of radiation, such as the sun's radiation -- sunlight.

Radiation during the operation of photovoltaic systems  

Photovoltaic power generation converts light energy directly into direct current electricity through the characteristics of semiconductors, and then converts the direct current electricity into alternating current electricity that can be used by us through an inverter.  

The picture  

Photovoltaic modules themselves do not generate any electromagnetic radiation when generating electricity, but inverters and other power and electronic equipment in operation will affect the surrounding electromagnetic environment, so all inverters have metal shielded shell, and comply with the global regulations of electromagnetic compatibility certification.  

As measured in the figure below, when the distance is about 10cm, the radiation value of the inverter is 0, while the radiation value of the induction cooker is 13.31.

Through scientific determination, the electromagnetic environment of solar photovoltaic power generation system is lower than the limits of each index.   In the working frequency band, the electromagnetic environment of the solar photovoltaic power station is even lower than that of the common household appliances in normal use, which will not affect human health.
