光伏发电对人体有危害吗

目前有一种新型的发电方式，就是太阳能光伏发电，太阳能光伏发电的原理就是把光能转换成电能。太阳能光伏发电目前是国家重点推广的一种绿色的新能源，很多人担心太阳能光伏发电会有辐射，对人体是有危害的，真相是什么呢？接下来我们一起来了解一下吧。

太阳能光伏发电有辐射吗？光伏发电对人体有危害吗？

如果说太阳能发电没有辐射，是不可能的，其实太阳能光伏发电是有些电磁辐射的，这个辐射并不是很多，非常的少。如果太阳能光伏发电设备合格，所产生的辐射不会对人体造成危害，且这一点辐射，也不会对其他设备造成影响和干扰。

光伏发电是通过半导体的特性将光能直接转换为直流电，再通过逆变器将直流电转换为我们可以使用的交流电。光伏系统由光伏组件、支架、直流电缆、逆变器、交流电缆、配电柜、变压器等组成，支架不带电，自然不会产生电磁干扰。

光伏组件和直流电缆中含有直流电流，方向不变。它们只能产生电场，而不能产生磁场。虽然输出变压器是交流电，但是频率很低，只有50Hz，产生的磁场也很低。逆变器是将直流电转换成交流电的装置。它包含电力电子转换，频率一般为5-20KHz，因此会产生交变电场，因此也会产生电磁辐射。但国家对光伏逆变器的电磁兼容性有着严格的标准。与家用电器相比，光伏逆变器的电磁辐射与笔记本电脑差不多，低于电磁炉、电吹风、冰箱等。
Does solar PV have radiation? Is photovoltaic power generation harmful to the human body?

If solar power generation has no radiation, it is impossible, in fact, solar photovoltaic power generation has some electromagnetic radiation, this radiation is not very much, very little. If the solar photovoltaic power generation equipment is qualified, the radiation generated will not cause harm to the human body, and this radiation will not affect and interfere with other equipment.

Photovoltaic power generation is the direct conversion of light energy into direct current through the characteristics of semiconductors, and then the conversion of direct current into alternating current that we can use through the inverter. The photovoltaic system is composed of photovoltaic modules, brackets, DC cables, inverters, AC cables, distribution cabinets, transformers, etc., and the brackets are not charged and naturally do not produce electromagnetic interference.

PV modules and DC cables contain DC currents in the same direction. They can only generate electric fields, not magnetic fields. Although the output transformer is alternating current, the frequency is very low, only 50Hz, and the magnetic field generated is also very low. An inverter is a device that converts direct current into alternating current. It contains power electronic conversion, the frequency is generally 5-20KHz, so it generates an alternating electric field, so it also generates electromagnetic radiation. However, the country has strict standards for the electromagnetic compatibility of photovoltaic inverters. Compared with household appliances, the electromagnetic radiation of photovoltaic inverters is similar to that of laptops, and lower than that of induction cookers, hair dryers, refrigerators, etc.
