目前有一種新型的發(fā)電方式，就是太陽能光伏發(fā)電，太陽能光伏發(fā)電的原理就是把光能轉(zhuǎn)換成電能。太陽能光伏發(fā)電目前是國家重點推廣的一種綠色的新能源，很多人擔心太陽能光伏發(fā)電會有輻射，對人體是有危害的，真相是什么呢？接下來我們一起來了解一下吧。

太陽能光伏發(fā)電有輻射嗎？光伏發(fā)電對人體有危害嗎？

如果說太陽能發(fā)電沒有輻射，是不可能的，其實太陽能光伏發(fā)電是有些電磁輻射的，這個輻射并不是很多，非常的少。如果太陽能光伏發(fā)電設(shè)備合格，所產(chǎn)生的輻射不會對人體造成危害，且這一點輻射，也不會對其他設(shè)備造成影響和干擾。

光伏發(fā)電是通過半導(dǎo)體的特性將光能直接轉(zhuǎn)換為直流電，再通過逆變器將直流電轉(zhuǎn)換為我們可以使用的交流電。光伏系統(tǒng)由光伏組件、支架、直流電纜、逆變器、交流電纜、配電柜、變壓器等組成，支架不帶電，自然不會產(chǎn)生電磁干擾。

光伏組件和直流電纜中含有直流電流，方向不變。它們只能產(chǎn)生電場，而不能產(chǎn)生磁場。雖然輸出變壓器是交流電，但是頻率很低，只有50Hz，產(chǎn)生的磁場也很低。逆變器是將直流電轉(zhuǎn)換成交流電的裝置。它包含電力電子轉(zhuǎn)換，頻率一般為5-20KHz，因此會產(chǎn)生交變電場，因此也會產(chǎn)生電磁輻射。但國家對光伏逆變器的電磁兼容性有著嚴格的標準。與家用電器相比，光伏逆變器的電磁輻射與筆記本電腦差不多，低于電磁爐、電吹風(fēng)、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.
